Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Consider the following statements about types of processing units:

CPUs are general-purpose processors designed for sequential execution of tasks.

GPUs are application-specific processors limited to graphical rendering.

TPUs are optimized for neural network operations, making them ideal for AI model training.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: B

Explanation:

Statement 1: Correct. CPUs are general-purpose and work sequentially.

Statement 2: Incorrect. GPUs were originally for graphics but now support broader parallel processing, including machine learning.

Statement 3: Correct. TPUs are optimized for tensor operations, key to AI training.

Q2:

Leptobrachium aryatium, recently discovered in India, is

A: a species of freshwater fish found in the Brahmaputra River

B: a new butterfly species found in Arunachal Pradesh

C: a species of frog discovered in a forest near Guwahati

D: a new medicinal plant endemic to the Eastern Himalayas

Show

Answer: C

Explanation:

Leptobrachium aryatium is a newly discovered frog species found in Assam's Garbhanga Reserve Forest. Identified in 2025 by Purkayastha and team, it belongs to the Megophryidae family and is named after Arya Vidyapeeth College, Guwahati.

Known for its cryptic coloration, this species features a broad head, prominent eyes, and distinctive black markings aiding in camouflage. It inhabits moist, leaf-littered forest floors and is endemic to this biodiversity-rich region. Though not yet evaluated by the IUCN, it may face habitat-related threats. Its discovery highlights the ecological significance of Northeast India and the urgent need for habitat conservation efforts.

Q3:

Consider the following statements about Olive Ridley turtles:

They are known for mass nesting behavior called “arribada.”

Their sex determination is influenced by environmental factors like temperature and moisture.

They exclusively nest on India’s east coast during the breeding season.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: B

Explanation:

Statements 1 and 2 are correct. Olive Ridley turtles exhibit “arribada,” where thousands of turtles come ashore to nest in synchrony. Also, like other reptiles, temperature and moisture at nesting sites influence the sex of hatchlings (warmer temperatures typically produce more females).
However, Statement 3 is incorrect. While most nesting sites are on the east coast, such as Gahirmatha (Odisha), recent discoveries like turtle "03233" show nesting on the west coast (Maharashtra) too, indicating these turtles do not nest exclusively on the east coast.

Q4:

Consider the following statements:

Statement I: Qubits can exist in multiple states at the same time due to superposition.
Statement II: This enables quantum computers to solve optimization problems faster than classical computers.

Which of the following is correct?

A: Both Statement-I and Statement-II are correct, and Statement-II is the correct explanation of Statement-I

B: Both Statement-I and Statement-II are correct, but Statement-II is not the correct explanation of Statement-I

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

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

Show

Answer: A

Explanation:

Qubits exhibit superposition, allowing them to exist in multiple states simultaneously, unlike classical bits (0 or 1). This unique behavior, combined with entanglement, enables quantum computers to evaluate many possibilities at once, making them extremely efficient at solving complex optimization problems and large-scale simulations, particularly in fields like material science, logistics, and quantum chemistry.

Q5:

Consider the following statements regarding the Civil Registration System (CRS) in India:

The CRS is maintained by the Ministry of Health and Family Welfare.

From October 1, 2023, digital birth and death registration through CRS is the only official mode of certification.

The CRS database will be integrated with the National Population Register (NPR).

Digital birth certificates issued via CRS are now mandatory for school admissions, passport applications, and property registration.

How many of the above statements are correct?

A: Only one

B: Only two

C: Only three

D: All four

Show

Answer: C

Explanation:

Statement 1 is incorrect. CRS is maintained by the Office of the Registrar General of India (RGI) under the Ministry of Home Affairs, not Health Ministry.

Statements 2, 3, and 4 are correct. From October 1, 2023, digital-only registration is mandated, and CRS data will contribute to the NPR, forming a single source of demographic records for governance purposes.
