Frank's dream was to have his own shop ________ to produce the workings of his own hands.

A.that

B.in which

C.by which

D.how

答案及解析： B

解析：

此题意为“弗兰克的梦想是拥有一家展现他自己的经营模式的商店”。显然，_{____}to produce the working of his own hands是定语从句，说明shop的具体情况。而to produce the workings of his own hands是发生在这个shop中的，因此应该用in which，也就相当于in the shop，故选B。
