Q1:

Which of the following statements is correct with reference to dugongs?

A: Dugongs are carnivorous marine mammals.

B: Dugongs are found only in deep sea waters in India.

C: Dugongs play an important role in maintaining the seagrass ecosystem.

D: World Dugong Day is celebrated on 28 June.

Show

Answer: c

Explanation:

• Option A: is incorrect as dugongs are the only herbivorous marine mammals in India, which exclusively eat seagrass, and are not carnivorous.

• Option B: is incorrect as dugongs live in shallow coastal waters, such as the Andaman and Nicobar Islands, Gulf of Mannar, Palk Bay and Gulf of Kutch, and not in deep sea waters.

• Option C: is correct because dugongs, called "sea cows", play an important ecological role in maintaining the seagrass ecosystem by eating seagrass. They regulate the seagrass beds, thereby keeping the ecosystem balanced.

• Option D: is incorrect because World Dugong Day is celebrated on May 28, not June 28.

Hence, option C is the correct answer.

Q2:

Consider the following statements with reference to the first gene-edited sheep developed in India:

1. Gene-editing led to an increase in muscle mass by about 30%, which is not found naturally in common Indian breeds.

2. The gene-editing of this sheep was done using CRISPR-Cas9 technology, which has been awarded the Nobel Prize in Chemistry.

3. Since no foreign gene has been added to it, this sheep is considered transgenic under India's biotechnology policies.

Choose the correct answer from the options given below:

A: Only 1 and 2 are correct

B: Only 2 and 3 are correct

C: Only 1 and 3 are correct

D: All 1, 2 and 3 are correct

Show

Answer: A

Explanation:

• Statement 1 – Correct: Gene-editing has led to ~30% increase in muscle mass in sheep, which is not found in common Indian breeds.

• Statement 2 – Correct: The CRISPR-Cas9 technology used was the first to win the Nobel Prize in Chemistry in 2020.

• Statement 3 – Incorrect: Since no foreign gene has been added, it is not transgenic. India’s biotechnology policies treat transgenic and gene-edited organisms as different.

• Statement 2 is correct: The system covers the tropical region between 30°N to 30°S latitude which includes the entire Indian mainland.

• Statement 3 is incorrect: BFS can provide weather warnings up to Panchayat level.

Q4:

AI Matryoshka’, developed by Google, is related to:

A: A multi-layer AI ecosystem that will empower various applications

B: A quantum computing-based defense system

C: A biological neural network that mimics the human brain

D: An AI platform designed for a space exploration mission

Show

Answer: A

Explanation:

Google’s AI Matryoshka model is also an ecosystem spanning multiple layers around a central AI core, spanning various applications, APIs, developer tools, and user interfaces.

The name AI Matryoshka is derived from the “Matryoshka doll” (Russian nesting doll), where there are many smaller dolls within a larger doll.

Q5:

Recently India has achieved the status of the fourth largest global economy. Which of the following facts is correct in this context?

A: India's nominal GDP is estimated to reach $6 trillion by the year 2025-26.

C: According to the World Bank, a country is considered high-income if its per capita income is more than $14,005.

D: India's per capita income is likely to fall to $1,438 by the year 2025.

Answer: C

Explanation:

• (a) is incorrect: According to the IMF, India's nominal GDP is estimated to be $4.187 trillion in 2025-26, not $6 trillion.

• (b) is incorrect: India has now overtaken Japan and is only behind the US, China and Germany.

• (c) is correct: According to the World Bank definition, countries with a per capita income of more than $14,005 in 2024-25 are considered high-income.

• (d) is incorrect: India's per capita income is expected to increase to $2,880 by 2025, not fall to $1,438.
