Answer 2

1. My friend was sure that Ferdinand Magellan had discovered Australia. Explanation: We use the past perfect ("had discovered") to indicate an action that was completed before another past action ("was sure").

2. Our history teacher explained to us that the Revolutionary War in America took place in the 18th century. Explanation: Here, we use the simple past ("took place") to state a past event without any specific time relationship to other events.

3. Betty knew that she had done everything she could to win the competition. Explanation: The past perfect ("had done") is used to show that the action (doing everything she could) was completed before another past action ("knew").

4. We asked Professor Smith when he had come to Moscow and how many places of interest he had already seen. Explanation: Both "had come" and "had seen" are in the past perfect tense to show actions completed before another past action ("asked").

5. Little John believed that Canada was in the South of the American Continent. Explanation: In this case, "was" is used in the past tense to state a general belief in the past, without any specific time reference to another event.

6. We all wanted to know where in New York the Statue of Liberty was situated. Explanation: "Was situated" is used in the past tense to describe the location of the Statue of Liberty at a specific point in the past.

7. The children asked what cities in the USA we had seen. Explanation: "Had seen" is used in the past perfect tense because the action of seeing the cities occurred before the asking by the children.

8. Father told me that I had made a mistake in my school test. Explanation: "Had made" is in the past perfect tense because the mistake occurred before the telling by the father.

9. We all knew that Germany had declared war on several European countries in 1941. Explanation: The past perfect ("had declared") is used to indicate that the declaration of war happened before the knowing by "we all."

10. He said he had always supported me. Explanation: The past perfect ("had supported") is used to indicate an ongoing action (supporting) that happened before the speaking in the past.

11. Not all the pupils knew that the US President was the Commander in Chief of the country's armed forces. Explanation: In this case, "was" is used in the past tense to state a general fact in the past, without any specific time reference to another event.
