Question 1540

Which of the following is an Inert Gas?

AHydrogen

BNitrogen

COxygen

DArgon

Show answer

D. ArgonArgon (Ar) is an inert gas, also known as a noble gas. It belongs to Group 18 of the periodic table, whose elements are characterized by complete outer electron shells, making them chemically unreactive. Argon constitutes about 0.93% of the Earth's atmosphere and is widely used in electric bulbs, welding, and in creating inert environments for chemical reactions. Other options (for context) Hydrogen: Highly reactive and combustible gas. Nitrogen: Relatively less reactive but not inert; forms compounds like ammonia. Oxygen: Highly reactive gas essential for combustion and respiration.

Question 1539

Which of the following micro-organism causes diseases like polio and chicken pox?

ABacteria

BProtozoa

CAlgae

DVirus

Show answer

D. VirusDiseases like Polio and Chicken Pox are caused by viruses. The Polio virus attacks the nervous system and can lead to paralysis, while the Varicella-zoster virus causes Chicken Pox, characterized by itchy blisters and fever. Viruses are acellular infectious agents that can reproduce only inside the living cells of a host organism. Other options (for context) Bacteria: Cause diseases like tuberculosis, cholera, and typhoid, not polio or chicken pox. Protozoa: Cause diseases such as malaria and amoebiasis. Algae: Generally non-pathogenic; they do not cause human diseases like polio or chicken pox.

Question 1538

Who was the founder of Banaras Hindu University?

ASukumar Dutt

BMadan Mohan Malvia

CDr. Rajendra Prasad

DMotilal Nehru

Show answer

B. Madan Mohan MalviaExplanation not yet available.

Question 1537

Anti-defection law is given in which schedule of Indian constitution?

ASecond Schedule

BTenth Schedule

CThird Schedule

DFourth Schedule

Show answer

B. Tenth ScheduleExplanation not yet available.

Question 1536

Which instrument is used for measuring humidity of atmosphere?

ABarometer

BAnemometer

CThermometer

DHygrometer

Show answer

D. HygrometerA Hygrometer is an instrument used to measure the humidity (moisture content) in the atmosphere. It helps determine the percentage of water vapor present in the air, which is essential for weather forecasting, climate studies, and maintaining controlled environments in industries or laboratories. Some common types include the dry and wet bulb hygrometer and the digital hygrometer. Other options (for context) Barometer: Used to measure atmospheric pressure. Anemometer: Used to measure wind speed. Thermometer: Used to measure temperature.

Question 1535

The driest location on Earth is in which country?

AKenya

BChile

CCongo

DLibya

Show answer

B. ChileThe Atacama Desert

Question 1534

When iron rusts, its weight __________

Adecreases

Bincreases

Cremains the same

Dfirst increases and then decreases

Show answer

B. increasesWhen iron rusts, its weight increases. This is because rusting is a chemical reaction between iron, oxygen, and moisture from the air, forming hydrated iron(III) oxide (Fe₂O₃·xH₂O). During this process, oxygen atoms from the air combine with the iron, adding extra mass to the metal surface in the form of rust. However, while the weight increases, the structural strength of the iron decreases due to corrosion. Other options (for context) Decreases: Incorrect — mass increases due to the addition of oxygen. Remains the same: Incorrect — oxygen from air chemically adds to iron, increasing total mass. First increases and then decreases: Not applicable — in normal rusting, weight continues to increase until the surface flakes off.

Question 1533

In whose consultation does the President convene and prorogue all sessions of Parliament?

AThe Speaker

BThe Prime Minister

CThe Prime Minister and the leader of the opposition in Lok Sabha

DThe Council of Ministers

Show answer

B. The Prime MinisterExplanation not yet available.

Question 1532

What is commonly known as white plague?

ATyphoid

BMalaria

CTuberculosis

DPlague

Show answer

C. TuberculosisTuberculosis (TB) is commonly known as the "White Plague". It earned this name because it causes extreme paleness and weight loss in affected individuals. Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis, primarily affecting the lungs but can also spread to other parts of the body. It spreads through airborne droplets when an infected person coughs or sneezes. Other options (for context) Typhoid: Caused by Salmonella typhi, affects the intestine and causes high fever. Malaria: Caused by Plasmodium parasite transmitted through mosquito bites. Plague: Caused by Yersinia pestis, historically known as the “Black Death,” not the white plague.

Question 1531

General Dyer, who was responsible for Jallianwalan Bagh massacre, was shot dead by?

AHasrat Mohini

BVir Savarkar

CUdham Singh

DJatin Das
