Choose the correct answer. He _______ too much coffee last night and _______.

The correct answer is "drank, couldn't sleep". Here's why: * The first blank requires the past tense of "drink" because the sentence refers to an action that happened "last night." The past tense of "drink" is "drank." * The second blank needs a verb that indicates the result of drinking too much coffee the previous night. "Couldn't sleep" means "was not able to sleep", it is past tense because of the "last night" context. "Can't slept" isn't grammatically correct. Therefore, the complete and correct sentence is: "He drank too much coffee last night and couldn't sleep."
