Question 1423

The Kyoto Protocol is associated with :

AEnvironment

BNuclear Power

CTrade

Dnone of these

Show answer

A. EnvironmentThe Kyoto Protocol is an international agreement related to the environment, specifically aimed at reducing greenhouse gas emissions that contribute to global warming and climate change. It was adopted in Kyoto, Japan, in 1997 and came into force in 2005. The protocol set binding targets for developed countries to limit or reduce their carbon dioxide (CO₂) and other greenhouse gas emissions. Other options (for context) Nuclear Power: Not the focus of the Kyoto Protocol; this relates to energy generation and atomic energy regulation. Trade: Covered under agreements like GATT and WTO, not the Kyoto Protocol. None of these: Incorrect — the Kyoto Protocol deals specifically with environmental protection.

Question 1415

Green leafy vegetable are rich source of :

ACitric acid

BMalic acid

CFolic acid

Dnone of these

Show answer

C. Folic acidGreen leafy vegetables are a rich source of Folic Acid (Vitamin B₉). Folic acid is essential for the formation of red blood cells, DNA synthesis, and proper cell growth. It is particularly important for pregnant women, as it helps prevent neural tube defects in the developing fetus. Vegetables like spinach, kale, lettuce, and fenugreek leaves are excellent sources of folic acid. Other options (for context) Citric acid: Found mainly in citrus fruits like oranges and lemons. Malic acid: Commonly present in apples and other fruits, not in leafy greens. None of these: Incorrect — folic acid is the correct nutrient associated with green leafy vegetables.

Question 1412

Yellow revolution is related to:

Acereals

Boilseeds

Cmilk

Dnone of these

Show answer

B. oilseedsThe Yellow Revolution in India refers to the significant increase in the production of oilseeds. It was initiated to make India self-sufficient in edible oils such as mustard, sunflower, groundnut, and soybean oils. The revolution gained momentum under the Technology Mission on Oilseeds (TMO) launched in the 1980s. The key figure associated with the Yellow Revolution is Sam Pitroda. Other options (for context) Cereals: Their production growth is linked with the Green Revolution. Milk: Related to the White Revolution led by Dr. Verghese Kurien. None of these: Incorrect — the Yellow Revolution specifically concerns oilseeds.

Question 1410

Anaemia is caused due to deficiency of:

AIodine

BIron

CVitamin

Dnone of these

Show answer

B. IronAnaemia is caused due to a deficiency of iron in the body. Iron is an essential component of hemoglobin, the protein in red blood cells that carries oxygen. When the body lacks sufficient iron, it produces fewer and smaller red blood cells, leading to symptoms such as fatigue, weakness, dizziness, and pale skin. This condition is known as Iron-Deficiency Anaemia. Other options (for context) Iodine: Its deficiency causes goitre, not anaemia. Vitamin: Certain vitamins like B₁₂ and folic acid deficiency can cause anaemia, but the most common cause is lack of iron. None of these: Incorrect — iron deficiency is the main cause of anaemia.

Question 1409

Who invented insulin?

AJonas E. Salk

BAlexander Fleming

CF. Banting

DRoentgen

Show answer

C. F. BantingInsulin was discovered by Frederick Banting and Charles Best in 1921 at the University of Toronto. Banting and his team successfully isolated insulin from the pancreas, which became a breakthrough in the treatment of diabetes mellitus. For this discovery, Frederick Banting and J.J.R. Macleod were awarded the Nobel Prize in Physiology or Medicine in 1923. Other options (for context) Jonas E. Salk: Discovered the first successful polio vaccine. Alexander Fleming: Discovered penicillin, the first antibiotic. Roentgen: Discovered X-rays in 1895.

Question 1366

Silviculture is the management of :

ARivers

BLakes

CHills

DForests

Show answer

D. ForestsSilviculture is the branch of forestry concerned with the management, cultivation, and care of forests. It involves the practice of controlling the establishment, growth, composition, and quality of forest stands to meet diverse needs such as timber production, wildlife habitat, and environmental conservation. The term comes from Latin — silva meaning forest, and cultura meaning cultivation. Other options (for context) Rivers: Managed under hydrology or water resource management, not silviculture. Lakes: Managed under limnology or aquatic resource management. Hills: May be part of forest areas, but silviculture specifically refers to forest management.

Question 1365

Tajmahal is threatened mostly due to :

ASulphur dioxide

BCarbon dioxide

CCarbon monooxide

DWater Vapour

Show answer

A. Sulphur dioxideThe Taj Mahal is threatened primarily due to sulphur dioxide (SO₂) pollution. When sulphur dioxide released from nearby industries and vehicles mixes with moisture in the air, it forms sulphuric acid, leading to acid rain. This acid rain reacts with the white marble of the Taj Mahal, causing it to turn yellow and deteriorate — a phenomenon known as “Marble Cancer.” Other options (for context) Carbon dioxide: Contributes to global warming but does not directly damage marble. Carbon monoxide: Harmful to health but has minimal effect on marble structures. Water vapour: Naturally present in the atmosphere and not harmful to monuments.

Question 1364

Sound causes hazardous noise pollution at decibels:

AAbove 50

BAbove 80

CAbove 100

DAbove 130

Show answer

B. Above 80Sound becomes hazardous and causes noise pollution when its intensity exceeds 80 decibels (dB). Prolonged exposure to such high noise levels can lead to hearing loss, stress, sleep disturbances, and other health problems. Common sources include heavy traffic, loudspeakers, machinery, and construction activities. Sounds above 120 dB can cause immediate ear damage or pain. Other options (for context) Above 50 dB: Considered moderate — typical of normal conversation or office noise. Above 100 dB: Very loud and potentially painful, but 80 dB is the threshold for long-term hazard. Above 130 dB: Extremely loud, causes immediate physical pain and ear damage.

Question 1359

India first atomic device was exploded in 1974 at:

ABikaner

BBarmed

CPokhran

DJaisalmer

Show answer

C. PokhranIndia’s first successful atomic device was tested at Pokhran in the Thar Desert of Rajasthan on 18th May 1974. The operation was code-named "Smiling Buddha" and was conducted by the Bhabha Atomic Research Centre (BARC) under the leadership of scientists like Dr. Raja Ramanna. This event marked India’s entry into the group of nuclear-capable nations. Other options (for context) Bikaner: A city in Rajasthan, but no nuclear tests were conducted there. Barmer: Located near the Pakistan border, not the site of India’s nuclear test. Jaisalmer: Close to Pokhran geographically, but not the test location.

Question 1357

Big Bang theory explains:

AOrigin of Universe

BOrigin of Sun

CLaws of Chemistry

DLaws of History

Show answer

A. Origin of UniverseThe Big Bang Theory explains the origin of the Universe. According to this theory, the universe began about 13.8 billion years ago from an extremely hot and dense state that expanded rapidly in all directions. This expansion continues even today, leading to the formation of galaxies, stars, planets, and other cosmic structures. The discovery of the cosmic microwave background radiation provides strong evidence supporting the Big Bang Theory. Other options (for context) Origin of Sun: Explained by the Nebular Hypothesis, not the Big Bang Theory. Laws of Chemistry: Studied under physical and inorganic chemistry, unrelated to cosmology. Laws of History: Concern human civilizations, not the universe’s formation.
