　　Having a larger assortment to choose from increases consumers’ expectations about matching their preferences. The heightened expectations seem logical, since assortments containing more or more varied items should increase the degree to which preferences can be matched. In practice, however, as assortment size increases, the degree to which consumers realize better preference matches often rises relatively little. Larger assortments may not actually offer more variety, the market may simply not supply an envisioned offering, or in the absence of sophisticated search tools, consumers may miss a better preference match even if it is available. Therefore, larger assortments can increase the likelihood that expectations will not be met, leaving consumers less satisfied with options chosen from larger rather than smaller assortments.
　　1. In the highlighted portion of the passage, the author assumes that?
　　A. consumers’ attitude toward the assortment of choices they are presented with depends almost exclusively on the size of the range?.
　　B. consumers who have clear preferences make their choices more quickly than those whose preferences are relatively vague?.
　　C. consumers’ anticipation of meeting specific expectations directly affects their satisfaction with a selected option?.
　　D. consumers presented with an assortment of choices often adjust the preferences they had beforehand.
　　E. consumers presented with a larger assortment of choices often make their decisions too quickly.

　　前提假设题
　　解析：此题的提问方式，很像句子作用题，但是请注意，此题并没有问该高亮句是什么作用，而是问在高亮句中，the author assumes that。即，要想使得高亮句成立，需要补充一个什么假设。这正是逻辑单题中假设题的考法。阅读后一句话之后，要从半句推出高亮句，很大的逻辑漏洞在于，expectations和satisfaction是否有关系未知。从高亮句的表达，能够看出，作者是默认二者之间是有关联的，所以才能从前半句推导出高亮句。补足该漏洞，本题选C。A选项错，原文说larger assortments can increase the likelihood，表述的是一种可能性，而A选项直接说depends almost exclusively on the size of the range，与原文矛盾。B E选项错，本题的逻辑和是否quickly无关。D选项错，与the preferences they had beforehand无关。
