Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Which of the following statements regarding the Surrogacy (Regulation) Act, 2021 are correct?

It allows both commercial and altruistic surrogacy under regulated conditions.

It permits surrogacy access to never-married single women aged 25 years and above.

Only altruistic surrogacy is permitted under the Act.

All surrogacy clinics must be registered under the Act.

How many of the above statements are correct?

A: Only one

B: Only two

C: Only three

D: All four

Show

Answer: B

Explanation:

Statements 3 and 4 are correct. The Surrogacy (Regulation) Act, 2021 permits only altruistic surrogacy, explicitly banning commercial surrogacy to prevent exploitation. It also mandates mandatory registration of all clinics providing surrogacy services.
Statement 1 is wrong because commercial surrogacy is banned.
Statement 2 is incorrect because the Act permits surrogacy access only to widows or divorcees aged between 35 and 45 years—not never-married single women.
Thus, only two statements are correct.

Q2:

Which of the following statements about the newly developed HPV test kits are correct?

They are indigenously developed by Indian companies.

They use a chip-based RT-PCR method for detection.

They are designed exclusively for hospital-based testing, not point-of-care use.

They are affordable compared to conventional cervical cancer screening methods.

How many of the above statements are correct?

A: Only two

B: Only one

C: All four

D: Only three

Show

Answer: D

Explanation:

Statements 1, 2, and 4 are correct. The HPV test kits are indigenously developed by Molbio Diagnostics and Mylab Discovery, use chip-based RT-PCR technology, and are designed to be affordable, particularly for resource-constrained settings.
However, statement 3 is incorrect: these kits are specifically designed for point-of-care testing, enabling decentralized and faster cervical cancer screening outside major hospitals.
Thus, three statements are correct.

Q3:

Consider the following statements:

Statement I: Heavy metal pollution can cause respiratory disorders through inhalation.
Statement II: Particulate-bound heavy metals released into the atmosphere can travel long distances before deposition.

Which one of the following is correct?

A: Both Statement-I and II are correct and II explains I

B: Statement-I is correct but Statement-II is incorrect

C: Statement-I is incorrect but Statement-II is correct

D: Both Statement-I and II are incorrect

Show

Answer: A

Explanation:

Both statements are correct.
Heavy metals released from industrial units, smelters, and waste incineration bind to airborne particulates. These particulate-bound metals can travel long distances, entering the respiratory system of humans and animals upon inhalation, causing respiratory and systemic health issues.
Thus, II explains I: long-range atmospheric transport of heavy metals leads to inhalation exposure.

Q4:

Consider the following statements about Hypersonic Weapons and Technologies:

Hypersonic missiles can travel at speeds exceeding Mach 5.

Hypersonic Glide Vehicles (HGVs) require scramjet engines for propulsion.

Scramjet-powered missiles maintain constant atmospheric flight without leaving the atmosphere.

Hypersonic missiles are easier to track than ballistic missiles.

How many of the above are correct?

A: Only two

B: Only three

C: All four

D: Only one

Show

Answer: A

Explanation:

Statements 1 and 3 are correct.

Hypersonic missiles travel above Mach 5.

Scramjet-powered vehicles (hypersonic cruise missiles) stay within the atmosphere, using atmospheric oxygen for combustion.
Statement 2 is incorrect: HGVs are launched using traditional rockets and then glide at hypersonic speeds—they don't use scramjets.
Statement 4 is incorrect: hypersonic missiles are harder to detect and track because they fly at lower altitudes and maneuver unpredictably compared to predictable ballistic paths.

Q5:

The discovery of Labeo uru and Labeo chekida in the Western Ghats is significant for which of the following reasons?

A: They are the first species of freshwater fish found in India.

B: They are endemic to their respective river systems, emphasizing the biodiversity of the Western Ghats.

C: They are the first fish species to be discovered by the Centre for Peninsular Aquatic Genetic Resources.

D: Their discovery resolved the issue of overfishing in the region.

Show

Answer: B

Explanation:

The discovery of Labeo uru and Labeo chekida highlights the unique biodiversity of the Western Ghats, as both species are endemic to specific river systems (Chandragiri and Chalakudy rivers, respectively). This underscores the ecological richness and the presence of species that are confined to particular regions, underlining the Western Ghats as a biodiversity hotspot.
