1. Q1medium

   Which is the largest gland in the human body?

   • ALiver
   • BPancreas
   • CThyroid
   • DPituitary
   Show answer & solution

   Correct answer: (A) Liver

   The liver weighs about 1.5 kg in an adult. It secretes bile, stores glycogen and removes toxins. The thyroid is the largest endocrine gland, and the pituitary is called the 'master gland', but neither is the largest gland overall. So the answer is the liver.

2. Q2medium

   Which of the following diseases is caused by a virus?

   • ATyphoid
   • BMalaria
   • CTuberculosis
   • DMeasles
   Show answer & solution

   Correct answer: (D) Measles

   Measles is caused by the measles virus and can be prevented with the MMR/MR vaccine. Typhoid (Salmonella typhi) and tuberculosis (Mycobacterium tuberculosis) are caused by bacteria. Malaria is caused by the protozoan Plasmodium and spread by female Anopheles mosquitoes. So the viral disease is measles.

3. Q3medium

   In August 2023, the Vikram lander of India's Chandrayaan-3 mission made a soft landing near which region of the Moon?

   • ANorth polar region
   • BSea of Tranquillity near the equator
   • CSouth polar region
   • DCentre of the far side
   Show answer & solution

   Correct answer: (C) South polar region

   On 23 August 2023, the Vikram lander touched down near the lunar south pole. India became the first country to soft-land in that region, and the fourth to soft-land on the Moon at all. The landing point was named Shiv Shakti Point, and 23 August is now observed as National Space Day. Apollo 11 landed in the Sea of Tranquillity. So the answer is the south polar region.

4. Q4hard

   Which element is a non-metal that exists as a liquid at room temperature?

   • AMercury
   • BBromine
   • CIodine
   • DGallium
   Show answer & solution

   Correct answer: (B) Bromine

   Bromine, a reddish-brown halogen, is the only non-metal that is liquid at room temperature. Mercury is also liquid, but it is a metal. Iodine is a solid that sublimes, and gallium is a metal that melts at about 30 °C. So the answer is bromine.

5. Q5hard

   The SI unit of radioactivity is the:

   • ABecquerel
   • BCurie
   • CGray
   • DSievert
   Show answer & solution

   Correct answer: (A) Becquerel

   1 becquerel (Bq) means one nuclear decay per second. The curie is an older, non-SI unit (1 Ci = 3.7 × 10¹⁰ Bq). The gray measures absorbed radiation dose, and the sievert measures its biological effect (equivalent dose). So the SI unit of radioactivity is the becquerel.
