Indian Army Group C Mock Test - 7 - Indian Army Group C MCQ

The pattern followed is, 

Logic: For all the other option sum of place value is 14 except “DJA”

Hence, “DJA” is the correct answer.

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p² – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p² – 4)

⇒ x – 1/x = √(25² – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

Solar energy - Greenhouse effect - Incorrect

• The term ‘Greenhouse effect’ has been derived from a phenomenon that occurs in a greenhouse.
• A greenhouse looks like a small glasshouse and is used for growing plants, especially during winter.
• In a greenhouse, the glass panel lets the light in but does not allow heat to escape.
• Therefore, the greenhouse warms up, very much like inside a car that has been parked in the sun for a few hours. 
• The greenhouse effect is a naturally occurring phenomenon that is responsible for heating of Earth’s surface and atmosphere.
• Solar energy is trapped by the earth atmosphere and radiates slowly so as to cover our earth with a warm blanket.
• This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.
• Without the greenhouse effect, the average temperature at the surface of Earth would have been a chilly –18°C rather than the present average of 15°C.
• Carbon dioxide, methane and water vapour are the major greenhouse gases that absorb the infrared radiation from the Earth and re-emit it.
• It is not caused due to solar energy but due to greenhouse gasses.

Thus, the solar energy-greenhouse effect is not the correct pair.

Additional Information

Fossil fuel-burning - Release of CO₂ - Correct

• Carbon dioxide (CO₂) is released into the atmosphere by respiration, the burning of fossil fuels for energy.
• In recent years, their quantities have increased significantly due to the burning of fossil fuels.
• The increased amount of CO₂ in the air is mainly responsible for global warming.

Nuclear power - Radioactive wastes - Correct

• Initially, nuclear energy was hailed as a non-polluting way of generating electricity.
• Later on, it was realised that the use of nuclear energy has very serious inherent problems i.e. the generation of radioactive waste.
• Safe disposal of radioactive wastes is important in nuclear power energy factories.
• Improper disposal of nuclear waste can cause serious physical and biological deformities in living organisms when directly exposed to them. 

Biomass burning - Release of CO₂  - Correct

• Biomass burning means the burning of living or dead vegetation.
• It happens during land cleaning in the agriculture process when crops are out of the field.
• In this process, a high amount of CO₂ is released into the environment.

NABARD was established in 1982 to support the rural sector's development, following recommendations by the Shivaraman Committee.

The correct answer is 120 dB.

• The loud noises that continue for a prolonged period can cause High blood pressure, Eardrum damage, and Nervous breakdown.
• Noise is unwanted and undesirable sound or noise, an irritant, and a source of stress.
• The sound level meter is used for measuring the intensity of sound.
• The transport sector contributes the maximum noise.
• The roadway noise can be reduced by the use of noise barriers, limitation of vehicle speed, and alteration of roadway surface texture.
• Sound is measured in decibels.
• Noise pollution is considered to be caused by sounds louder than 120 decibels.
• The decibel scale is used for measuring the loudness of sound or noise.
• According to the research, noise pollution is the highest in a low-income neighbourhood.
• The level of sound during normal conversation is 60 dbA.
• The allowed noise level by World Health Organisation (WHO) in residential areas is 50 decibels.
• Noise pollution affects marine animal's behaviour.
• The main source of noise pollution is Heavy machinery and Transportation equipment.

When the soil has pH value greater than 11, it is termed as practically infertile.

Causes of high soil pH:

• Sources of alkalinity.
• Role of cations (Na and Ca)
• Influence of soluble salt levels
• Influence of carbon dioxide and carbonates.

Important Points 

1. If the pH in the case of saline soil is around 8.5, very good structure
2. And in the case of saline-sodic soil, it is from 8.5 to 10, good structure.
3. And in the case of sodic soil, it is generally greater than 10, structureless.

Note:

Why high pH soils are infertile:

The high pH caused due to the presence of sodium carbonate which is highly soluble.

This high pH causes fulvic and humic acid of organic matter to get dissolve and when the water evaporates, it gives the surface a black color.

This sodic soil creates physical disintegration and due to high sodium and low salt concentration, slaking, swelling and dispersion occurs which caused coagulation of soil particles as Vander Vaal forces dominate due to deficiency of hydrated ions. 

Complete dispersion causes soil crusting and as a result of this germination problem due to clogs that restrict soil and air movement and makes soil infertile.

NITI Aayog was indeed set up to replace the Planning Commission with a focus on cooperative federalism.

The correct option is B.
Between the years 1870 and 1880, Indian people had become politically conscious and by the year 1885, there was a platform ready for establishment of a political organization on a national basis. The credit for giving a definite structure to the all India organization goes to a retired British officer A.O. Hume. He was a liberal minded person. Hume had been feeling a need for a political organization which would bridge the gap between the rulers and the people being ruled. Hume wanted the people to adopt the path of valid politics instead of violence and aggression. With the efforts of Mr. Hume, "Indian National Union" was formed.
Hume obtained the permission from Lord Dafrin to convene a meeting of "Indian national Union" between 25th December and 313st December in Pune. The objective of the meeting was to acquaint the work force with one another, which was working for the national development and define a political agenda for the development.
Although the place of convention was decided to be Pune, the venue was changed to Mumbai in the last minute. The convention was held at Mumbai on 28th December 1885 in Gokuldas Tejpal Sanskrit College. At the suggestion of Sir Hume the meeting was named "Indian national Congress" and thus, Indian National Congress was born. There were 72 representatives in this convention of the Indian National Congress. Vyomesh Chandra Benarjee was the president of the first convention of Indian National Congress.
The Objectives of establishment of Indian National Congress- Historians believe that, with the direction from British Government Huma and his colleagues had founded Indian National Congress as a protective shield for British Government. Hume did not want the people of India to adopt violent and aggressive measures to register their discontent and anger against British Rule. Hume wanted to encourage people to take a legitimate path of protest like-appeals, memorandum, delegations to influence the British Government, in order to fulfil the demands.
The leaders of Congress accepted the leadership of A.O. Hume in the foundation of Indian National Congress because they were not in the position of having an open conflict with the British Government in the existing circumstances. This was more sensible to cooperate with Hume, in order to have a common platform wherein they could discuss the problems of the country.

Segregation of Waste: Waste Can be segregated as

• Bio-Degradable Waste: 
  • Waste that can be decomposed by microorganisms. 
  • It includes organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves, wood, and paper.​
• Non-Bio Degradable Waste:
  • ​Waste that cannot be decomposed by microorganisms.
  • It includes plastic, rubber, glass, electronic waste, etc. 

Explanation:

Non-Biodegradables can be disposed of by following the 3Rs: 

• Reduce: If the old objects (bags, water bottles, clothes) are in good condition, it's better to keep using them rather than buying new things. 
• Reuse: Jam or pickle jars or plastic bottles can be used again to store small objects like buttons. 
• Recycle: Paper, glass, some plastics, and metals can be recycled. 

Wood is biodegradable, it can be made into compost but cannot be recycled.
