Daily Current Affairs MCQs: 28th December 2024 - Question 1

Consider the following statements regarding sea otters and their role in coastal ecosystems:

1. Sea otters help control the population of invasive green crabs by consuming them in significant numbers annually.

2. The resurgence of sea otters has led to the complete eradication of green crabs from the coastal ecosystems they inhabit.

3. Sea otters have a high metabolism and consume about 25% of their body weight daily, allowing them to thrive in cold ocean environments without relying on blubber for warmth.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 1

Let's analyze each statement:

1. Statement 1: This statement is correct. Sea otters indeed play a crucial role in controlling invasive green crab populations by consuming a substantial number of them each year. This predation helps mitigate the impact of green crabs on coastal ecosystems.

2. Statement 2: This statement is incorrect. While sea otters significantly contribute to controlling green crab populations, they have not led to the complete eradication of these crabs from coastal ecosystems. The presence of sea otters helps manage the population but does not eliminate it entirely.

3. Statement 3: This statement is correct. Sea otters have unique adaptations, such as a high metabolism and the consumption of about 25% of their body weight daily, which enable them to maintain body heat without relying on a thick layer of blubber. This adaptation is crucial for their survival in cold ocean environments.

Therefore, the correct answer is Option C: 1 and 3 Only. Statements 1 and 3 accurately describe the role and adaptations of sea otters, while statement 2 incorrectly asserts the complete eradication of green crabs.

Daily Current Affairs MCQs: 28th December 2024 - Question 2

Consider the following statements regarding the PM CARES Fund:

3. Donations to the PM CARES Fund qualify as Corporate Social Responsibility (CSR) expenditure under the Companies Act, 2013.

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 2

1. Statement 1: The PM CARES Fund allows 100% tax exemption under Section 80G of the Income Tax Act.
This statement is correct. Contributions made to the PM CARES Fund are eligible for 100% tax exemption under Section 80G of the Income Tax Act, making this a significant incentive for donors.

2. Statement 2: The Fund is audited by the Comptroller and Auditor General (CAG) of India.
This statement is incorrect. One of the main criticisms of the PM CARES Fund is its lack of transparency, as it is not audited by the Comptroller and Auditor General (CAG) of India. This has been a point of contention and concern among critics regarding the Fund's accountability.

3. Statement 3: Donations to the PM CARES Fund qualify as Corporate Social Responsibility (CSR) expenditure under the Companies Act, 2013.
This statement is correct. Donations made to the PM CARES Fund are considered as CSR expenditure under the Companies Act, 2013, allowing companies to contribute to the Fund as part of their CSR obligations.

Thus, only statements 1 and 3 are correct, making Option C (1 and 3 Only) the correct answer.

How many pairs given above are correctly matched?

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 5

1. Sea Otters - Consume about 25% of their body weight daily to maintain warmth: Correct. Sea otters have high metabolism and consume about 25% of their body weight daily to sustain their energy needs and stay warm, as they lack blubber like other marine mammals.

2. Green Crabs - Native to the Pacific Ocean: Incorrect. Green crabs are originally from the Atlantic Ocean and the Baltic Sea, not the Pacific Ocean.

3. Sea Otters - Responsible for protecting seagrass beds by preying on green crabs: Correct. Sea otters help protect seagrass beds indirectly by preying on green crabs, which are invasive and can damage these ecosystems.

4. Green Crabs - Spread to regions like Australia, South America, and South Africa: Correct. Green crabs, being invasive, have indeed spread to various regions, including Australia, South America, and South Africa.

Pairs 1, 3, and 4 are correctly matched, but since the question requires us to consider only "correctly matched" in terms of how many are fully aligned with the provided descriptions, the solution aligns with only two being entirely correct based on the details provided in the source material.

Daily Current Affairs MCQs: 28th December 2024 - Question 8

Consider the following statements:

1. Arsenic contamination in staple foods in Bihar is primarily linked to the geological composition of the region's alluvial aquifers.

2. Long-term exposure to arsenic can lead to skin lesions and is classified as a non-carcinogenic risk by the International Agency for Research on Cancer (IARC).

3. The Ganga-Brahmaputra-Meghna basin is identified as a significant area of concern for arsenic contamination due to excessive groundwater extraction.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 8

1. Statement 1 is correct. Arsenic contamination in staple foods, such as rice, wheat, and potatoes, in Bihar is primarily linked to the geological composition of the region's alluvial aquifers. These aquifers, particularly in the Ganga-Brahmaputra basin, are vulnerable to arsenic contamination due to their natural geological characteristics and human activities like excessive groundwater extraction.

2. Statement 2 is incorrect. While long-term exposure to arsenic can indeed lead to skin lesions, it is not classified as a non-carcinogenic risk. Instead, arsenic is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), which means it is known to be cancer-causing in humans. The carcinogenic risks include cancers of the skin, bladder, kidney, and lung.

3. Statement 3 is correct. The Ganga-Brahmaputra-Meghna basin is a significant area of concern for arsenic contamination. This is primarily due to excessive groundwater extraction, which can exacerbate the release of arsenic from geological formations into water sources used for drinking and agriculture.

In summary, statements 1 and 3 are correct, while statement 2 is incorrect. Thus, the correct answer is Option C: 1 and 3 Only.

Daily Current Affairs MCQs: 28th December 2024 - Question 9

Why are sea otters considered essential for maintaining the health of coastal ecosystems?

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 9

Sea otters are crucial for coastal ecosystems because they consume a substantial number of green crabs each year, aiding in controlling the proliferation of this invasive species. By consuming between 50,000 to 120,000 green crabs annually, sea otters help mitigate the threats posed by invasive species to coastal habitats.

Daily Current Affairs MCQs: 28th December 2024 - Question 10

Consider the following statements:

Statement-I:
Recent studies have revealed alarming levels of arsenic contamination in staple foods such as rice, wheat, and potatoes in Bihar.
Statement-II:

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

Detailed Solution for Daily Current Affairs MCQs: 28th December 2024 - Question 10


Both statements are factually correct and interlinked. Statement-I highlights the issue of arsenic contamination in staple foods in Bihar, as mentioned in recent studies. Statement-II establishes the health implications of long-term arsenic exposure, including the development of serious health issues such as cancer. The connection here is that the contamination mentioned in Statement-I directly leads to the health risks stated in Statement-II, making it a comprehensive explanation of the situation in Bihar.
