Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Consider the following statements regarding the Air Quality Life Index (AQLI):

1.   It is developed by the World Health Organization (WHO).

2.   AQLI quantifies the impact of PM2.5 pollution on human life expectancy.

3.   The 2025 edition of AQLI is based on global data from the year 2023.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 and 3 only

C: 1 and 3 only

D: 1, 2 and 3

Show

Answer: B

Explanation:

Statement 1 is incorrect:
The Air Quality Life Index (AQLI) is not developed by the World Health Organization. It is developed by the Energy Policy Institute at the University of Chicago (EPIC).

Statement 2 is correct:
AQLI measures the impact of PM2.5 air pollution on life expectancy, showing how much longer people could live if air quality met WHO standards.

Statement 3 is correct:
The 2025 edition of AQLI is based on data from the year 2023, reflecting a two-year data lag commonly used in global reports.

Q2:

With reference to the Air Quality Life Index (AQLI) 2025, consider the following statements:

1.   Air pollution is identified as the most severe health threat in India, reducing the average life expectancy by over 5 years.

2.   According to the report, all of India’s population lives in areas exceeding the WHO’s PM2.5 guideline.

3.   Delhi-NCR shows the highest potential life expectancy loss due to air pollution in India.

4.   PM2.5 pollution is now the second-largest external risk to global life expectancy, after smoking.

Which of the statements given above are correct?

A: 1 and 3 only

B: 2 and 4 only

C: 2 and 3 only

D: 1, 2 and 3 only

Show

Answer: C

Explanation:

Statement 1: Incorrect

The report states that air pollution reduces average life expectancy by 3.5 years, not over 5 years.

Statement 2: Correct

The report clearly states that 100% of India’s population lives in areas exceeding the WHO PM2.5 guideline of 5 µg/m³.

Statement 3: Correct

Delhi-NCR is at the top of the list with residents potentially losing 8.2 years of life due to PM2.5 pollution, the highest in the country.

Statement 4: Incorrect

According to AQLI 2025, PM2.5 pollution is now the biggest external risk to human life expectancy, surpassing smoking, malnutrition, and infectious diseases.

Q3:

With reference to CEREBO, recently launched in India, consider the following statements:

1.   It is an invasive diagnostic tool for detecting Traumatic Brain Injuries (TBIs).

2.   The device uses near-infrared spectroscopy and machine learning to detect intracranial bleeding and cerebral edema.

3.   It does not requires advanced radiological infrastructure and trained radiologists for operation.

4.   CEREBO is designed for use even in rural and emergency settings.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 and 4 only

C: 1 ,3 and 4 only

D: 2, 3 and 4 only

Show

Answer: D

Explanation:

Statement 1: Incorrect

CEREBO is a non-invasive diagnostic device. It does not require penetration of the body or any invasive procedure.

Statement 2: Correct

The device operates using near-infrared spectroscopy powered by machine learning algorithms to detect intracranial bleeding and cerebral edema.

Statement 3: correct

A major advantage of CEREBO is that it does not require advanced infrastructure or trained radiologists. In fact, it can be operated by paramedics or even unskilled users after 30 minutes of training.

Statement 4: Correct

The device is designed specifically for rural, emergency, ambulance, and disaster settings.

Q4:

With reference to Vikram 3201, consider the following statements:

1.   Vikram 3201 is India’s first fully indigenous 32-bit microprocessor.

2.   It is designed primarily for commercial applications such as smartphones and laptops.

3.   The processor has been developed jointly by ISRO and the Semiconductor Laboratory (SCL), Chandigarh.

Which of the statements given above are correct?

A: 1 and 3 only

B: 1, 2 and 3

C: 3 only

D: 2 only

Show

Answer: A

Explanation:

Statement 1: Correct

Vikram 3201 is indeed India’s first fully indigenous 32-bit microprocessor, specifically space-grade.

Statement 2: Incorrect

Unlike commercial processors used in consumer devices like smartphones or laptops, Vikram 3201 is designed for launch vehicles and spacecraft systems, i.e., space missions — not consumer electronics.

Statement 3: Correct

It has been jointly developed by ISRO and the Semiconductor Laboratory (SCL), Chandigarh, a key facility under the Department of Space.

Q5:

With reference to semiconductors and the India Semiconductor Mission (ISM), consider the following statements:

1.   Semiconductors are materials that can behave as both conductors and insulators.

2.   The India Semiconductor Mission (ISM) was launched in 2021 with the aim of establishing a self-reliant semiconductor and display manufacturing ecosystem in India.

3.   The Design-Linked Incentive (DLI) scheme under ISM focuses on promoting large-scale chip manufacturing facilities in India.

4.   Semiconductors are crucial not only for consumer electronics but also for sectors like defense, space, and healthcare.

Which of the statements given above are correct?

A: 1, 2 and 4 only

B: 1, 3 and 4 only

C: 2, 3 and 4 only

D: 1, 2, 3 and 4

Show

Answer: A

Explanation:

Statement 1: Correct

Semiconductors have the unique property of behaving as both conductors and insulators, enabling precise control of electrical signals — this is why they are vital to electronic circuits.

Statement 2: Correct

The India Semiconductor Mission (ISM) was launched in December 2021 with a budget of ₹76,000 crore to create a self-reliant semiconductor and display ecosystem.

Statement 3: Incorrect

The Design-Linked Incentive (DLI) scheme under ISM does not promote large-scale manufacturing directly.

It is specifically aimed at supporting chip design, including ICs, SoCs, and other components — especially by startups and domestic companies.

Statement 4: Correct

Semiconductors are essential not just for smartphones and computers but also for defense systems, space technology, medical equipment, and more — forming the backbone of digital and automated systems.
