Answer 2

Passive Voice to Active Voice:

1. "He was made to solve the problem immediately" to passive voice:

The active voice of this sentence would be: "Someone made him solve the problem immediately."

Explanation: In the original sentence, the subject "he" is receiving the action of being made to solve the problem. To convert it to active voice, we need to identify the doer of the action and make it the subject of the sentence. In this case, "someone" is the doer of the action, so we can rewrite the sentence with "someone" as the subject.

2. "My friend's mother didn't let him buy a collection of beautiful stones" to passive voice:

The active voice of this sentence would be: "He was not allowed to buy a collection of beautiful stones by my friend's mother."

Explanation: In the original sentence, the subject "my friend's mother" is preventing the action of him buying a collection of beautiful stones. To convert it to passive voice, we need to make the subject of the original sentence the object of the passive sentence and use the appropriate form of the verb "to be" (in this case, "was not allowed").

3. "The doctor made the nurse test the patient's blood pressure again" to passive voice:

The active voice of this sentence would be: "The nurse was made to test the patient's blood pressure again by the doctor."

Explanation: In the original sentence, the subject "the doctor" is causing the action of the nurse testing the patient's blood pressure. To convert it to passive voice, we need to make the subject of the original sentence the object of the passive sentence and use the appropriate form of the verb "to be" (in this case, "was made").

Active Voice to Passive Voice:

1. "Most of European governments were made to stop nuclear tests" to active voice:

The passive voice of this sentence would be: "Someone made most of the European governments stop nuclear tests."

Explanation: In the original sentence, the subject "most of the European governments" is being forced to stop nuclear tests by someone. To convert it to active voice, we need to identify the doer of the action and make it the subject of the sentence. In this case, "someone" is the doer of the action, so we can rewrite the sentence with "someone" as the subject.
