they (prepare,prepared ) their things before going to a vacation
Answer (1)
The sentence: They (prepare or prepared) their things before going to a vacation.The correct grammar here is prepared because it is the past tense of the word "prepare". Since the sentence says that they prepared their things before going to a vacation, before is the key word here. It is past tense. So the past tense of prepare is prepared. Hence, prepared is the right answer.
