But a look at the strange variations in tuition reveals that the choice about which college to attend doesnt come down merely to dollars and cents.
【分析】本句为复合句，主架为a look reveals。that引导宾语从句，作reveals的宾语。about which college to attend为介词短语作choice的后置定语。which college to attend为宾语从句，作about的宾语。come down to指取决于。
【译文】但是看一下学费的奇怪变化，就可以知道选择去哪所大学不仅仅取决于金钱了。
