Key Points

Rainwater Harvesting Methods

Kulhs

These are water harvesting methods used in the hilly areas of the Western Himalayas.
These systems are trenches that were dug to help divert water from rivers to be used for agriculture and into the villages for domestic use.
They are used to transport melted water from glaciers to villages due to the effect of gravity.
Under this system, water from the streams is diverted into man-made channels that carry this water to various villages.
They serve as a source of canal irrigation for agricultural crops.
Being a hilly area, it was not possible to build tube wells and borewells in Himachal Pradesh. That's why ';kulhs' came into existence.

Khadin and Jhodas

This method is used in thearid areas of Rajasthanfor water conservation.
In arid areas, agricultural fields are converted into rain-fed storage structures.
It is an indigenous construction designed to harvest surface runoff water for agriculture.
Its main feature is a very long (100-300 m) earthen embankment built across the lower hill slopes lying below gravelly uplands.
The khadin system is based on the principle of harvesting rainwater on farmland and subsequent use of this water-saturated land for crop production.

Madakas, Ahar, Pynes, Surangas

Ancient rainwater harvesting methods followed in India include Madakas, Ahar, Pynes, Surangas. Hence option 4 is correct.
They were practised majorlyin rural areas.

Additional Information

Tankas are big concrete containers which are made for rainwater harvesting.
In this method, hilltops are cut in a way that they act like a big tank to store the water
The Bamboo Drip Irrigation systemis used in Meghalaya.
It is a 200-year-old system of using bamboo pipes to transport.
Bamboos are connected to the source of flowing water to the fields
About 18-20 litres of water enters the bamboo pipe system, gets transported over hundreds of metres, and finally reduces to 20-80 drops per minute at the site of the plant.

Primary sector is the largest employer in India. It employes about 64% of the Indian population.
This sector produces only a quarter of GDP because in it, the first step of goods production takes place. It is the supplier of raw material to the secondary sector. And the value of the good increases on each subsequent step and primary sector provides the first step. So, it's share is quite less in GDP.

Which of the following is not correct about ecosystem?

" }, "answerExplanation": { "@type": "Comment", "text": "

The correct answer isIt is a closed system.
Key Points

Ecosystem:
- Ecosystem, a natural resource system, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
- An ecosystem is an open system that can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Hence,statement 3 is incorrect.
- Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem.
- The fundamental source of energy in almost all ecosystems is radiant energy from the Sun.
- The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.e., they can use the energy of sunlight to convert carbon dioxide and water into simple, energy-rich carbohydrates.
- The autotrophs use the energy stored within the simple carbohydrates to produce the more complex organic compounds, such as proteins, lipids, and starches, that maintain the organisms’ life processes.
- The autotrophic segment of the ecosystem is commonly referred to as the producer level.

Additional Information

The organic matter generated by autotrophs directly or indirectly sustains heterotrophic organisms.
Heterotrophs are the consumers of the ecosystem; they cannot make their own food.
They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs.
All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.
Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level, composed of those organisms that make their own food; the primary consumer level, composed of those organisms that feed on producers; the secondary consumer level, composed of those organisms that feed on primary consumers; and so on.
The movement of organic matter and energy from the producer level through various consumer levels makes up a food chain.
For example, a typical food chain in a grassland might be grass (producer) → mouse (primary consumer) → snake (secondary consumer) → hawk (tertiary consumer).
Actually, in many cases the food chains of the ecosystem overlap and interconnect, forming what ecologists call a food web.
The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.
A food chain in which the primary consumer feeds on living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway.
Both pathways are important in accounting for the energy budget of the ecosystem.

Nigeria leads the global fight against meningitis, introducing the groundbreaking Men5CV vaccine, endorsed by WHO, targeting five strains in one shot. This surpasses previous vaccines, vital as bacterial meningitis, prevalent in Africa, poses serious health risks. Africa’s “meningitis belt,” including Nigeria, faces escalating cases, with a 50% rise reported last year by WHO. Nigeria’s pioneering move sets a precedent for broader adoption worldwide, marking a significant stride in public health.

" }, "answerExplanation": { "@type": "Comment", "text": "

The Correct Option is C: 1 and 3
Characteristics of the Neolithic Culture
The Neolithic culture, also known as the New Stone Age, was a significant period in human history characterized by several key features that distinguish it from earlier Paleolithic cultures. The chief characteristic features of the Neolithic culture are:
1. Practice of Agriculture:

The most significant development during the Neolithic period was the shift from a hunter-gatherer lifestyle to settled farming communities.
People began to cultivate crops such as wheat, barley, rice, and maize, which led to the establishment of permanent settlements.
Agriculture provided a stable food supply and allowed for surplus production, leading to population growth.

2. The Technology of Smelting Metal Ore:

While the Neolithic culture is primarily associated with the use of stone tools, some advancements in metalworking began to emerge during this period.
The technology of smelting metal ore, particularly copper, started to develop, paving the way for the later Bronze Age.
The ability to extract and work with metals revolutionized tool production, leading to more efficient and durable tools and weapons.

3. Domestication of Animals:

Another significant characteristic of the Neolithic culture was the domestication of animals.
Early humans began to tame and breed animals for various purposes, such as food, labor, and companionship.
Commonly domesticated animals during this period included cattle, sheep, goats, pigs, and dogs.
Domestication of animals provided a stable source of food, materials (such as wool and leather), and assistance in agricultural activities.

Therefore, the correct answer is C: 1 and 3 only, as the Neolithic culture is primarily characterized by the practice of agriculture and the domestication of animals. The technology of smelting metal ore, although emerging during this period, is more closely associated with later periods such as the Bronze Age.

The logic follows here is:

In a figure:

Middle number =(Top number× bottom number) - (left number× right number)

In fig 1:

Middle number = (9× 10) - (7× 8)

= 90 - 56

= 34

In fig 2:

Middle number = (12× 8) - (8× 7)

= 96 - 56

Similarly,

In fig 3:

Middle number =(11× 7) - (4× 9)

? = 77 - 36

? = 41

The Logic followed here is:

The third number = The First number× (second number÷ 2)

In Row 1:-10, 4, 20

The third number = 10× (4÷ 2)

= 10× 2 = 20

In Row 2:- 15, 8, 60

The third number = 15× (8÷ 2)

= 15× 4= 60

Similarly,

In Row 3:- 25, 8, ?

The third number = 25× (8÷ 2)

? = 25× 4= 100

Hence, the correct answer is'100'.

Given:

Length of rectangle = 3/5 of radius of circle

Radius of circle = Side of square with area 6400m2

Breadth of rectangle = 15 m

Formulas used:

Area of square = (Side)²

Perimeter of rectangle = 2(Length + Breadth)

Calculation:

Area of square = 6400m2

⇒ Side²= 6400

⇒ Side =√6400 = 80 m

Radius of cirlce = Side of square = 80 m

⇒ Length of rectangle = 3/5× 80 = 48 m

∴ Perimeter of the rectangle = 2(48 + 15) m

⇒ 126 m

The logic follows here is:

Given code = (Positional value÷ 2)3

Positional value of"V" = 22

22÷ 2 = 11

(11)3= 1331

Positional value of"P" = 16

16÷ 2 = 8

(8)3= 512

Similarly,

Positional value of"J" = 10

10 ÷ 2 = 5

(5)3= 125

Hence, the correct answer is"125".

P, Q, R, S, T, V, W, and Z are sitting around a circle facing at the centre not necessarily in this same order.

i)T is second to the right ofR whois third to the right of P.

Mistake Points

Whois used for thesecond personin a connecting statement.

For example:

T is second to the right of R who is third to the right of P.

Here,whois used for Rand not for T.

ii)S is second to the left of P and fourth to the right of Q.

iii)V whois not an immediate neighbour of P. (This means V cannot sit immediate left or right of P).

iv)Z is third to the right ofV

Thus we can see R is second to the right of W

From the final arrangement, we get V sits second to the right of S.
Hence, Option B is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

4’s multiples are:
12, 16, 20, 24, …
a = 12 and d = 4
2 is the remainder for 250 / 4.

A motor car does a journey in 17.5 hours, covering the first half at 30 km/h and the second half at 40 km/h. Find the distance of the journey.

" }, "answerExplanation": { "@type": "Comment", "text": "

If the car does half the journey @ 30 kmph and the other half at 40 kmph it’s average speed can be
estimated using weighted averages.
Since, the distance traveled in each part of the journey is equal, the ratio of time for which the car
would travel would be inverse to the ratio of speeds. Since, the speed ratio is 3:4, the time ratio
for the two halves of the journey would be 4:3. The average speed of the car would be:
(30 × 4 + 40 × 3)/7 = 240/7 kmph.
It is further known that the car traveled for 17.5 hours (which is also equal to 35/2 hours).
Thus, total distance = average speed × total time = (240 × 35)/(2 × 7) = 120 × 5 = 600 km

Given:

Odd numbers from 1 to 100.

Formula used:

The sum of n of odd number = n²

Where, n = Number of terms

Number of terms = (First terms + Last terms)/2

Average = The sum of all number/(Total number)

Calculation:

The odd numbers between 1 to 100,

1 + 3 + 5 + ..........+ 99

Number of terms = (First terms + Last terms)/2

⇒ n = (1 + 99)/2

⇒ n = 50

According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A(through these points by the shortest distance), he has to follow a path point A→ B→ F→ E.

Thus travelling from point A, he will pass the firstpoint B.

Hence, the correct answer is "Point B".

From Statement 1:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

Here, we can’t find the code for ‘Time’.

From Statement 2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

Here, we can’t find the code for ‘Time’.

From Statement1 and Statement2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

Here, we can’t find the confirm code for ‘Time’.

Hence option D is correct.

The correct answer is 1, 2, 3, 4 and 5

Key Points

Rainwater Harvesting Methods

Kulhs

These are water harvesting methods used in the hilly areas of the Western Himalayas.
These systems are trenches that were dug to help divert water from rivers to be used for agriculture and into the villages for domestic use.
They are used to transport melted water from glaciers to villages due to the effect of gravity.
Under this system, water from the streams is diverted into man-made channels that carry this water to various villages.
They serve as a source of canal irrigation for agricultural crops.
Being a hilly area, it was not possible to build tube wells and borewells in Himachal Pradesh. That's why ';kulhs' came into existence.

Khadin and Jhodas

This method is used in thearid areas of Rajasthanfor water conservation.
In arid areas, agricultural fields are converted into rain-fed storage structures.
It is an indigenous construction designed to harvest surface runoff water for agriculture.
Its main feature is a very long (100-300 m) earthen embankment built across the lower hill slopes lying below gravelly uplands.
The khadin system is based on the principle of harvesting rainwater on farmland and subsequent use of this water-saturated land for crop production.

Madakas, Ahar, Pynes, Surangas

Ancient rainwater harvesting methods followed in India include Madakas, Ahar, Pynes, Surangas. Hence option 4 is correct.
They were practised majorlyin rural areas.

Additional Information

Tankas are big concrete containers which are made for rainwater harvesting.
In this method, hilltops are cut in a way that they act like a big tank to store the water
The Bamboo Drip Irrigation systemis used in Meghalaya.
It is a 200-year-old system of using bamboo pipes to transport.
Bamboos are connected to the source of flowing water to the fields
About 18-20 litres of water enters the bamboo pipe system, gets transported over hundreds of metres, and finally reduces to 20-80 drops per minute at the site of the plant.

Which of the following is not correct about ecosystem?

A.
It comprises both, abiotic and biotic components.
B.
It has its own productivity.
C.
It is a closed system.
D.
It is a natural resource system.

Detailed Solution for Bihar Police SI Mains Paper 2 Mock Test - 3 - Question 21

The correct answer isIt is a closed system.
Key Points

Ecosystem:
- Ecosystem, a natural resource system, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
- An ecosystem is an open system that can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Hence,statement 3 is incorrect.
- Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem.
- The fundamental source of energy in almost all ecosystems is radiant energy from the Sun.
- The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.e., they can use the energy of sunlight to convert carbon dioxide and water into simple, energy-rich carbohydrates.
- The autotrophs use the energy stored within the simple carbohydrates to produce the more complex organic compounds, such as proteins, lipids, and starches, that maintain the organisms’ life processes.
- The autotrophic segment of the ecosystem is commonly referred to as the producer level.

Additional Information

The organic matter generated by autotrophs directly or indirectly sustains heterotrophic organisms.
Heterotrophs are the consumers of the ecosystem; they cannot make their own food.
They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs.
All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.
Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level, composed of those organisms that make their own food; the primary consumer level, composed of those organisms that feed on producers; the secondary consumer level, composed of those organisms that feed on primary consumers; and so on.
The movement of organic matter and energy from the producer level through various consumer levels makes up a food chain.
For example, a typical food chain in a grassland might be grass (producer) → mouse (primary consumer) → snake (secondary consumer) → hawk (tertiary consumer).
Actually, in many cases the food chains of the ecosystem overlap and interconnect, forming what ecologists call a food web.
The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.
A food chain in which the primary consumer feeds on living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway.
Both pathways are important in accounting for the energy budget of the ecosystem.

1 and 2 only
B.
3 only
C.
1 and 3 only
D.

Detailed Solution for Bihar Police SI Mains Paper 2 Mock Test - 3 - Question 26

The most significant development during the Neolithic period was the shift from a hunter-gatherer lifestyle to settled farming communities.
People began to cultivate crops such as wheat, barley, rice, and maize, which led to the establishment of permanent settlements.
Agriculture provided a stable food supply and allowed for surplus production, leading to population growth.

2. The Technology of Smelting Metal Ore:

While the Neolithic culture is primarily associated with the use of stone tools, some advancements in metalworking began to emerge during this period.
The technology of smelting metal ore, particularly copper, started to develop, paving the way for the later Bronze Age.
The ability to extract and work with metals revolutionized tool production, leading to more efficient and durable tools and weapons.

3. Domestication of Animals:

Another significant characteristic of the Neolithic culture was the domestication of animals.
Early humans began to tame and breed animals for various purposes, such as food, labor, and companionship.
Commonly domesticated animals during this period included cattle, sheep, goats, pigs, and dogs.
Domestication of animals provided a stable source of food, materials (such as wool and leather), and assistance in agricultural activities.
