D. Neither 1 nor 2
Statement 1 is incorrect: Sounding rockets are one or two stage solid propellant rockets used for probing the upper atmospheric regions and for space research.
Statement 2 is incorrect: Small Satellite Launcher (SSLV) uses three solid fuel-based stages not two solid fuel bases and a liquid fuel-based velocity trimming module (VTM).

Q3. Consider the following statements regarding Lactose Intolerance:
1. It is the inability of a person to digest lactose.
2. It is caused by a deficiency of the intestinal enzyme lactase.
3. Beyond the age of five, lactose in milk, cannot be naturally broken down in the stomach. Which of the above statement/s is/are correct?
A. 2 and 3 only
B. 1 and 3 only
C. 3 only
D. 1,2 and 3
Statement 1 is correct: Milk has been a part of the human diet for thousands of years. But a lot of people end up feeling uneasy, bloated or excessively gassy after consuming milk. If one experiences such symptoms, they are most likely to be lactose intolerant. It is simply the body’s inability to absorb milk lactose or a milk allergy.
Lactose intolerance is the inability of a person to digest lactose, the principal sugar in milk, that gives rise to gastrointestinal symptoms.
Statement 2 is correct: Lactose intolerance is caused by a deficiency of the intestinal enzyme lactase that acts on lactose to convert it into glucose and galactose which are then absorbed from the intestine. Primary symptoms of lactose intolerance are diarrhoea, flatulence (passing gas), and abdominal pain. Abdominal bloating, abdominal distension and nausea may also occur. Lactose intolerance is treated with dietary changes,
Statement 3 is correct: Studies on the global prevalence of this mutation suggest that 65% of humanity is lactose-intolerant, meaning they lack the gene to break down lactose into adulthood. Beyond the age of five, lactose, a sugar present in milk, cannot be naturally broken down in the stomach and this remains in the gut causing flatulence, acidity, and diarrhoea
Q4. Presence of which of the following in e-waste makes it hazardous for environment?
D. Bisphenol A
The presence of elements like lead, mercury, arsenic, cadmium, hexavalent chromium, and flame retardants beyond the threshold quantities make e-waste hazardous in nature.
Q5. Consider the following statements:
1. Alpha radiation occurs when the nuclides of high atomic mass have a higher neutron to proton ratio than stable nuclide.
2. Alpha radiation is negatively charged, and gamma radiation is neutral.
Which of the statement/s given above is / are correct?
A. 1 only
B. 2 only
C. Both 1 and 2
D. Neither 1 nor 2
Statement 1 is incorrect: Alpha Radiation: The emission of a He nucleus. Alpha radiation is common when the nuclides of high atomic mass have a lower neutron to proton ratio than stable nuclide and ejects an alpha particle.
Statement 2 is incorrect: Alpha particle is positively charged and gamma particle is neutral.
Beta particles have a mass which is half of one thousandth of the mass of a proton and carry either a single negative (electron) or positive (positron) charge.
Q6. Sanchi Stupa is depicted on which of the following Indian currency note?
A. 100 rupees
B. 200 rupees

Q7. R0(read as R-Naught) sometimes seen in news is about which of the following?
B. Contagiousness of a pathogen
C. Recycle Reuse & Reduce plastics
Reproduction Number (Ro) (pronounced R naught) is used to describe the intensity of an infectious disease outbreak.
» Ro is the number of cases, on average, an infected person will cause during their infectious period. The larger this number, more contagious is the disease.
» It can be viewed as the product of three numbers (i) the number of days an infected person remains infective (i.e., can infect others), (ii) the number of susceptible persons available to infect and (iii) the chance that a susceptible person gets infected

Statement 2 is correct: Being a RNA virus HIV mutates easily. HIV has already been recorded as one of the most rapidly mutating viruses. According to a report in Nature, the virus genes vary from one person to another who has tested positive for it. At times, it differs within one individual.
