With reference to the World Food Programme (WFP), consider the following statements:

1. It is a United Nations agency that works to fight hunger around the world.

2. It has been operating in India since 1963.

3. It was awarded the Nobel Peace Prize in 2020 for its work.

How many of the statements given above are correct?

A: Only one

B: Only Two

C: All three

D: None

Answer: C

Explanation:

Recently, the World Food Programme (WFP) has launched an emergency operation to provide food assistance for up to one million people affected by the recent escalation between Israel and Hezbollah in Lebanon. The World Food Programme is a United Nations agency that works to fight hunger and promote food security around the world. Hence, statement 1 is correct.


The World Food Programme has been operating in India since 1963 with the mission to ensure access to enough nutritious food for everyone. Hence, statement 2 is correct.


The World Food Programme was awarded the Nobel Peace Prize in 2020 for its work to provide food assistance in conflict areas and to prevent the use of food as a weapon of war. Hence, statement 3 is correct.


Q2:

Consider the following statements about the Crew-9 Mission:

1. It is a joint NASA-Roscosmos spaceflight mission to the International Space Station (ISS).

2. Sunita Williams and Barry Wilmore are expected to return to Earth in 2025 aboard the SpaceX Dragon spacecraft.

Which of the statements given above is/are correct?

A: 1 only

B: 2 only

C: Both 1 and 2

D: Neither 1 nor 2

Answer: B

Explanation:

Recently, NASA and SpaceX launched the Crew-9 mission to the International Space Station (ISS). The Crew-9 mission is a joint NASA-SpaceX spaceflight mission. Hence, statement 1 is incorrect.


This mission aims to bring astronauts to the International Space Station (ISS) for a five-month science mission and return Indian-origin astronaut Sunita Williams and NASA astronaut Barry Wilmore in 2025. The mission was launched from Cape Canaveral Space Force Station in Florida. Hence, statement 2 is correct.


Q3:

Consider the following statements about Pollen:

1. It delivers male gametes to the stigma of seed-producing plants.

2. Pollen grains are considered a sporophyte involved in the fertilization process.

3. Pollen grains are protected by a natural polymer called sporopollenin.

4. Pollen from anemophilous plants can cause allergic reactions, such as hay fever.

How many of the above statements are correct?

A: Only one

B: Only Two

C: Only Three

D: All four

Answer: C

Explanation:

Recently, a study suggested that giant woolly mammoths may have gone extinct due to pollen allergies. Pollen is a vital reproductive substance used by many plants for reproduction, delivering male gametes to the stigma of seed-producing plants. Hence, statement 1 is correct.


It is considered a gametophyte, a multicellular organism involved in the fertilization process. Each pollen grain consists of reproductive cells (which form sperm) and non-reproductive cells (which produce the pollen tube). Hence, statement 2 is incorrect.


Pollen grains appear as a powder when aggregated and are protected by a natural polymer called sporopollenin, which shields them during transport and environmental conditions. Hence, statement 3 is correct.


Pollen from anemophilous plants (e.g., birch, hickory) can cause allergic reactions, with grass pollen leading to hay fever. The study of pollen is known as palynology. Hence, statement 4 is correct.


Q4:

Recently, the Indian Cultural Association, in collaboration with Swami Vivekananda Cultural Centre, celebrated Onam in which of the following countries?

A: Nepal

B: Bangladesh

C: Sri Lanka

D: Maldives

Answer: C

Explanation:

Recently, the Indian Cultural Association, in collaboration with Swami Vivekananda Cultural Centre, continued Onam celebrations in Colombo, Sri Lanka. Sri Lanka is an island country located in the Indian Ocean, south of India, separated by the Palk Strait and Gulf of Mannar. The official capital is Sri Jayawardenepura Kotte, while Colombo is the commercial capital and largest city. Hence, option (c) is correct.


Q5:

Consider the following statements:

Statement-I:

Stem cells have the ability to self-renew, meaning they can divide indefinitely to replenish other cells.

Statement-II:

Stem cells can only develop into one specific type of cell, such as muscle cells.

 

Which of the following is correct in respect of the above statements?

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 and Statement-II is not the correct explanation for Statement-I

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

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

Answer: C

Explanation:

Recently, the first successful treatment using chemically induced pluripotent stem cells was conducted. Stem cells are unique cells that have the remarkable ability to develop into various specialized cell types in the body. They play a crucial role in the processes of growth, development, and tissue repair. Stem cells can divide and replicate indefinitely, helping to replenish other cells within the body. They have the ability to be induced or transformed into specialized cells, such as muscle cells, brain cells, or other specific cell types needed for the body's functioning. Here, statements I and II both are correct but statement II is not the correct explanation for statement I. Hence, option (c) is correct.
