Solution (a)

Explanation:

• Demographic Winter refers to the significant decline in birth rates in certain regions or countries, leading to an aging population and a decline in overall population. This phenomenon is a concern in many developed countries where birth rates have fallen below the replacement level of 2.1 children per woman. It can result in long-term economic challenges due to a shrinking workforce and increased strain on social services for the elderly. (Option (a) is correct)
• Overpopulation occurs when a region’s population exceeds its capacity to provide for basic needs such as food, housing, and healthcare. (Option (b) is incorrect)
• Population Aging or an Aging Society is where the number of elderly people increases relative to the younger population, creating challenges for healthcare and pensions. (Option (c) is incorrect)
• Rapid urbanization occurs when large numbers of people move from rural to urban areas, often in search of better opportunities, which can lead to depopulation in rural areas. (Option (d) is incorrect)

Solution (d)

Explanation:

• Paris Agreement focuses on limiting global warming to well below 2°C by reducing greenhouse gas emissions, particularly CO2. While related to global environmental issues, this is not the focus of the Montreal Protocol or Kigali Amendment.
• The Convention on Biological Diversity (CBD) aims to conserve ecosystems and protect species diversity. It is not linked to the Montreal Protocol or the Kigali Amendment, which specifically target ozone-depleting substances and HFCs.
• Initiatives like REDD+ (Reducing Emissions from Deforestation and Forest Degradation), which aim to reduce deforestation and promote afforestation to combat climate change.
• The Montreal Protocol is a global agreement to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs). The Kigali Amendment, adopted in 2016, is an extension of the Montreal Protocol aimed at phasing down hydrofluorocarbons (HFCs), which are potent greenhouse gases but do not deplete the ozone layer. This has dual benefits: protecting the ozone layer and reducing global warming potential. (Option (d) is correct)

Solution (b)

Explanation:

• The primary function of a telescope is not to make objects appear larger (magnification), but to collect more light from distant objects, allowing us to see fainter and more distant objects that are not visible to the naked eye. Magnification is a secondary function. (Statement 1 is incorrect)
• The light-gathering power of a telescope is a critical factor in determining its effectiveness. Telescopes with larger apertures can collect more light, which helps astronomers see fainter objects. This is why professional telescopes have very large mirrors or lenses to maximize their ability to collect light. (Statement 2 is correct)
• The apparent magnitude is a measure of an object’s brightness as seen from Earth. It works on a reverse scale: the lower the magnitude number, the brighter the object. For example, a star with an apparent magnitude of 1 is brighter than a star with a magnitude of 5. (Statement 3 is correct)

Solution (a)

Explanation:

• Metformin is one of the most widely used drugs for treating type 2 diabetes. It helps control blood sugar levels by improving the body’s sensitivity to insulin and decreasing glucose production in the liver. It is often the first-line medication for managing type 2 diabetes. (Statement 1 is correct)
• Pioglitazone is another drug used in the treatment of type 2 diabetes. It works by increasing the body’s sensitivity to insulin, allowing the body to use insulin more effectively. It belongs to a class of drugs called thiazolidinediones (TZDs). (Statement 2 is correct)
• Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID), commonly used to reduce pain, fever, and inflammation. It is not used for the treatment of diabetes. While it has medical uses, it does not play a role in managing blood sugar levels in diabetic patients. (Statement 3 is incorrect)
