1. Those buildings were destroyed by the fire last night.

Explanation: The verb "destroyed" is in the past tense, indicating that the action of destroying the buildings happened in the past. The phrase "by the fire last night" further confirms that the destruction occurred recently.

2. This modern watch is made in China.

Explanation: The verb "is made" is in the present tense passive voice, indicating that the action of making the watch is ongoing or repeated in the present, and it is done by someone or something else. The phrase "in China" specifies the location where the watch is made.

3. Sometimes fires can be caused by lightning.

Explanation: The correct variant is "lightning." Lightning is a natural occurrence that produces sparks of electricity, which can ignite fires. The other options (thunders, flood, magic, necessity) do not typically cause fires.

4. Tommy was at home, he was doing his homework from 3 till 5 o’clock.

Explanation: The correct variant is "was doing." This variant indicates that Tommy was engaged in an ongoing action of doing his homework during the specified time frame (from 3 to 5 o'clock). The use of the past continuous tense here shows that the action was happening continuously in the past.

5. Do you know that hurricanes usually start in warm waters?

Explanation: The correct variant is "warm waters." Warm waters provide the necessary heat and moisture for a hurricane to form and strengthen. The other options (big cities, calm places, cold waters, deserts) do not typically serve as the starting point or favorable conditions for hurricanes.
