Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Consider the following features of DSLIG (Dual-Sided Superhydrophobic Laser-Induced Graphene):

1.     It combines solar and electric heating for consistent desalination.

2.     It prevents salt deposition due to its superhydrophilic nature.

3.     It is made from PVDF and PES-based layers.

4.     It is effective in desalinating seawater, brackish water, and industrial wastewater.

How many of the above statements are correct?

A: Only one

B: Only two

C: Only three

D: All four

Show

Answer: C

Explanation:

Statements 1, 3, and 4 are correct. DSLIG’s dual heating mechanism (solar + Joule heating) ensures stable temperatures regardless of sunlight conditions. It is made of PVDF (for hydrophobicity) and PES (for mechanical strength). It has been successfully tested in lab settings for various water types.
However, statement 2 is incorrect. DSLIG is superhydrophobic, not superhydrophilic, which helps repel salt and prevent crystal accumulation on the evaporator surface—thereby maintaining long-term desalination efficiency.

Q2:

Consider the following statements regarding Type 5 Diabetes:

It primarily affects overweight adults in urban areas of developed countries.

It is caused by prolonged undernutrition affecting insulin production.

It has autoimmune markers similar to Type 1 diabetes.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: A

Explanation:

Only statement 2 is correct. Type 5 diabetes arises from prolonged undernutrition, especially in childhood, affecting pancreatic development and insulin secretion. Statement 1 is incorrect as it affects undernourished adolescents in LMICs, not overweight adults in developed nations. Statement 3 is also incorrect; unlike Type 1 diabetes, Type 5 does not show autoimmune markers.

Q3:

Consider the following statements regarding the International Big Cat Alliance (IBCA):

IBCA is a legally recognized intergovernmental organization with its headquarters in India.

India has committed ₹150 crore towards IBCA’s operations till 2028–29.

IBCA focuses exclusively on conservation of Old World big cats such as tiger, lion, and snow leopard.

The Alliance aims to promote transboundary conservation and international collaboration.

How many of the above statements are correct?

A: Only two

B: Only three

C: All four

D: Only one

Show

Answer: B

Explanation:

Statements 1, 2, and 4 are correct. The IBCA became a treaty-based intergovernmental alliance in 2025, with India as its host and headquarters. The country has committed ₹150 crore from 2023–24 to 2028–29 to support its operations. The alliance promotes transboundary conservation, scientific collaboration, and capacity building. However, statement 3 is incorrect. IBCA includes both Old World and New World big cats, such as jaguar and puma, along with tiger, lion, snow leopard, etc.

Q4:

Consider the following statements:

Statement I: India recorded a record-high total export value in FY 2024–25, driven largely by a surge in goods exports.
Statement II: Electronics and coffee exports were among the fastest-growing segments, contributing to this export performance.

Which of the following is correct?

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

B: Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I

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

D: Statement-I is correct, but Statement-II is incorrect

Show

Answer: C

Explanation:

India's total exports hit a record $820.93 billion, but goods exports were flat (only marginally rising to $437.42 billion). The main driver was services exports, which grew by 12.45%. So, Statement-I is incorrect.
However, Statement-II is correct. Electronics exports surged 32%, largely due to iPhone assembly in India, and coffee exports jumped 40%, aided by global shortages from Brazil’s drought.

Q5:

According to the India Justice Report 2025, which state has successfully met caste-based reservations in both the police and district judiciary?

A: Kerala

B: Karnataka

C: Andhra Pradesh

D: Tamil Nadu

Show

Answer: B

Explanation:

Karnataka stands out as the only large or mid-sized state in the report to have met the SC, ST, and OBC reservation quotas in both the police and the district judiciary sectors, reflecting its commitment to inclusive representation in justice delivery.
