Answer: Option 4 — 1, 2 and 3

All three statements are correct regarding the writs issued by Courts in India. Statement 1 correctly describes that Mandamus does not lie against private organisations unless they are entrusted with a public duty. Statement 2 is correct as written because Government ownership alone does not make a company subject to Mandamus without the element of public duty. Statement 3 accurately states that any public-minded person can petition for Quo Warranto to challenge illegal usurpation of public office.

✅ Statement 1 – Correct: Mandamus is issued to compel performance of public duties and does not lie against private organisations unless they are entrusted with a public duty.

✅ Statement 2 – Correct: Mandamus will not lie against a company merely because it is a Government Company; the company must be discharging a public duty for Mandamus to be applicable.

✅ Statement 3 – Correct: Quo Warranto can be sought by any public-minded person to inquire into the legality of a person's claim to a public office, unlike other writs which require an aggrieved party.

📝 Short Notes: Writs under Articles 32 and 226

• Article 32: Right to Constitutional Remedies - Supreme Court can issue writs for enforcement of Fundamental Rights (cannot be suspended except under Article 359 during Emergency)
• Article 226: High Courts have wider power to issue writs for any purpose, not just Fundamental Rights violations
• Mandamus Key Point: Cannot be issued against President or Governor (Article 361 immunity), against private individuals (unless public duty involved), or to enforce a contract

Answer: Option 4 — Neither 1 nor 2

Both statements are incorrect regarding the radiative effects of high and low clouds. High clouds are thin and primarily trap outgoing infrared radiation, causing warming rather than cooling. Low clouds are thick and primarily reflect incoming solar radiation, causing cooling rather than warming.

❌ Statement 1 – Incorrect: High clouds (like cirrus) are thin and allow solar radiation to pass through but trap outgoing infrared radiation from Earth's surface, thereby warming the surface rather than cooling it.

❌ Statement 2 – Incorrect: Low clouds (like stratus and cumulus) are thick and excellent reflectors of solar radiation, reflecting sunlight back to space, thereby causing a cooling effect rather than a warming effect.

📝 Short Notes: Cloud Types and Their Radiative Effects

• Albedo Effect: Low clouds have high albedo (30-60%), reflecting significant solar radiation, while high clouds have low albedo (10-30%).
• Greenhouse Effect: High clouds trap infrared radiation more effectively due to their cold tops and thin structure, enhancing the greenhouse effect.
• Climate Impact: Overall, low clouds have a net cooling effect on climate (~-30 W/m²), while high clouds have a net warming effect (~+10 W/m²).
• Cloud Feedback: Changes in cloud cover and types are among the largest uncertainties in climate change predictions.

Answer: Option 2 — Second half of the month of June

The longest day of the year in the northern hemisphere is known as the summer solstice, which typically occurs on June 20th or 21st, falling in the second half of June. On this day, the sun is directly overhead at the Tropic of Cancer (23.5°N latitude), resulting in maximum daylight hours in the northern hemisphere. The exact date may vary slightly from year to year due to the calendar system and Earth's orbital mechanics.

📝 Short Notes: Solstices and Equinoxes

• During solstices, the sun is directly overhead at either the Tropic of Cancer (June) or Tropic of Capricorn (December)
• During equinoxes, the sun is directly overhead at the Equator, resulting in equal day and night globally
• The tilt of Earth's axis (23.5°) is responsible for seasonal variations and solstices
• The term 'solstice' comes from Latin 'sol' (sun) and 'sistere' (to stand still), as the sun appears to pause at its northernmost or southernmost position
