Vicuna-7b-v1.1 can get this right with a slightly tuned prompt: Prompt: The following is a logic question. Answer it based on analysis of the logic only, not based on actual weather: "Any day that it rains, I drive home from work. If today I did not drive home from work, did it rain?" Response: Based on the information provided, it can be concluded that it did not rain today, since the speaker did not drive home from work. This is because the statement "If today I did not drive home from work, it rained" is true only if it rained. Since it is known that the speaker did not drive home from work, it can be inferred that it did not rain.
