  4. It cannot be used as an additive in petrol.

How many statements are correct?

Answer: B

Explanation:

·         Statement (3): Ethanol is highly soluble in water in all proportions, making it miscible with water. This makes statement 3 correct.


·         Statement (4): Ethanol can be used as an additive in petrol, and it can be mixed with petrol in any concentration, even up to pure ethanol (E100). Thus, statement 4 is incorrect.

Q5:

Assertion (A): Glacial Lake Outburst Floods (GLOFs) occur when a glacial lake suddenly releases water due to the failure of its natural dam.

Reason (R): GLOFs are short-lived but highly destructive events, with floods that last from hours to days, causing severe damage due to large downstream river discharges.

Options:

A: Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct explanation for Assertion (A).

B: Both Assertion (A) and Reason (R) are correct, but Reason (R) is not the correct explanation for Assertion (A).

C: Assertion (A) is correct, but Reason (R) is incorrect.

D: Assertion (A) is incorrect, but Reason (R) is correct.

Answer: B

Explanation:


·         Assertion (A): GLOFs indeed occur when a glacial lake, which has built up water behind a natural dam (often made of ice or debris), suddenly releases this water due to dam failure, resulting in catastrophic flooding downstream. This is a correct statement.


·         Reason (R): GLOFs are short-lived but highly destructive events, typically lasting only from hours to days. The release of water from the glacial lake causes large downstream river discharges, which can lead to severe damage to infrastructure, properties, and ecosystems. This statement is also correct, however Reason (R) is not the correct explanation for Assertion (A).
