At any rate, he hit upon a way of making a living, with no competitors.
A、No matter how hard he worked, he failed to make a living.
B、No matter what other people said, he succeeded in making a living.
C、Whatever the case might be,he happened to find a way of supporting himself.
D、Whatever the result might be .he insisted on his own way of supporting himself.
【正确答案】：C
【题目解析】：at any rate是指“（强调事情的真实性）无论如何，不管怎样”,与whatever同义。hit upon是指“突然有个好主意，突然想到一个妙点子"。因此，此句句意可理解为：不管情况怎样.他还是碰巧找到了一条谋生的好路子。选项A认为“他没有找到谋生之路”，与题意相反，因此不选。题干只是说他找到了谋生的办法，并没有说“他能很好地谋生”，也没有说“他坚持自己的谋生之路”，因此选项B、D不正确。答案为C。
