Do you understand the sentence as whole? Do you understand every option? If we take the sentence: J’adore le cyclisme, donc je ne vais jamais au collège... Let's decompose it: What is: J'adore, Le cyclisme, jamais and collège? Right so J'adore is I love, Le cyclisme = biking , jamais = never and collège = school ? And a)by car b)during summer) c)on tuesdays You don't go during summer because it's holiday time right not because you like cycling, it makes no sense doesn't it? You go to school on tuesdays don't you? So it's answer and it makes sense because you don't drive to school because you like biking.
