Current Affairs Quiz 20 February 2026

Q1. With reference to Tensor Cores and Tensor Processing Units (TPUs), consider the following statements:

1. Tensor Cores are specialised hardware units designed to accelerate matrix multiplications.
2. TPUs were developed to optimise neural network computations at hyperscale.
3. Both are examples of general-purpose sequential processors.

Which of the above statements are correct?
A) 1 and 2 only
B) 2 and 3 only
C) 1 and 3 only
D) 1, 2 and 3

Q1. (A)

Explanation:

• Statement 1 – Correct: Tensor Cores (introduced in NVIDIA GPUs like Volta architecture onward) are specialised units that accelerate matrix and tensor operations (e.g., FP16, BF16 multiplications), which are core to deep learning training and inference.
• Statement 2 – Correct: Tensor Processing Units (TPUs), developed by Google, are custom ASICs optimised for neural network workloads at hyperscale (Google Cloud, data centres).
• Statement 3 – Incorrect: Both Tensor Cores and TPUs are specialised parallel accelerators, not general-purpose sequential processors. Sequential complex instruction execution is the domain of CPUs.

Q2. With reference to recent AI Impact Summits, consider the following statements:

1. The AI Impact Summit 2027 is scheduled to be hosted in Geneva.
2. The AI Impact Summit 2028 is proposed to be hosted by the United Arab Emirates.
3. The AI Impact Summit 2027 will be hosted under the aegis of the World Trade Organization (WTO).

How many of the above statements are correct?
A) Only one
B) Only two
C) All three
D) None

Q2. (B)

Explanation:

• Statement 1 – Correct: The 2027 AI Impact Summit is to be hosted in Geneva, Switzerland.
• Statement 2 – Correct: The UAE is proposed host for the 2028 AI Summit, reflecting diffusion of AI norm-setting beyond traditional Western centres.
• Statement 3 – Incorrect: Although Geneva hosts WTO and other UN bodies, the AI Impact Summit is not formally under the WTO framework. It is a broader AI governance platform.

Q3. Which of the following pollutants are commonly released during crop residue burning?

1. PM2.5
2. Nitrogen Oxides (NOx)
3. Carbon Monoxide (CO)
4. Black Carbon

Select the correct answer:
A) 1 and 2 only
B) 1, 2 and 3 only
C) 1, 3 and 4 only
D) 1, 2, 3 and 4

Q3. (D)

Explanation:
All listed pollutants are released during stubble burning:

• PM2.5: Fine particulate matter directly affects respiratory health.
• NOx: Contributes to ozone formation and secondary particulate formation.
• CO: Produced due to incomplete combustion.
• Black Carbon: Short-lived climate pollutant with strong warming potential.

Q4. Kamlang Tiger Reserve is located in:

A) Assam
B) Arunachal Pradesh
C) Nagaland
D) Sikkim

Q4. (B)

Explanation:
Kamlang Tiger Reserve (also called Kamlang National Park) is located in Arunachal Pradesh, in the Lohit district.

• Lies in the Eastern Himalayan biodiversity hotspot.
• Important in context of hydropower projects in the Brahmaputra basin.
• Assam → Kaziranga, Manas
• Arunachal Pradesh → Namdapha, Kamlang
• Nagaland → Intanki
• Sikkim → Khangchendzonga

Q5. India’s import dependence for fertilizers is highest for which of the following?

A) Urea
B) DAP
C) Potash
D) SSP

Q5. (C)

Explanation:

• Potash – Nearly 100% import dependent (highest).
• DAP – Around 90% import dependent.
• Urea – Around 75% import dependent.
• SSP – Mostly domestically produced.
