Choose the correct form of the verb. I wish the temperature _______, it's too cold now. We'll have to light a big fire not to get cold.

The correct answer is "didn't drop". Here's why: This sentence uses the "I wish" structure to express a regret or a desire for something to be different in the present. When using "I wish" to talk about the present, we typically use the past simple tense. In this case, the speaker is wishing that the temperature were not so cold *now*. Therefore, we need the past simple form of "drop" in the negative, which is "didn't drop". So the completed sentence is: I wish the temperature didn't drop, it's too cold now. We'll have to light a big fire not to get cold.
