In recent years, many cabinetmakers have been winning acclaim as artists. But since furniture must be useful, cabinetmakers must exercise their craft with an eye to the practical utility of their product. For this reason, cabinetmaking is not art.
Which of the following is an assumption that supports drawing the conclusion above from the reason given for that conclusion?
Some furniture is made to be placed in museums, where it will not be used by anyone.
Some cabinetmakers are more concerned than others with the practical utility of the products they produce.
Cabinetmakers should be more concerned with the practical utility of their products than they currently are.
An object is not an art object if its maker pays attention to the object's practical utility.
Artists are not concerned with the monetary value of their products.
前提：近几年越来越多的家具木工被人们称赞为艺术家。但是由于家具必须是有用的，所以家具木工在施展手艺的时候必须留意自己的产品的实用性。
结论：出于这个原因，家具木工不是艺术家。
逻辑链：因为木工要留意实用性，所以他们不是艺术家。
为什么留意实用性就不是艺术家了呢？中间少了一环，而D项“如果一个东西的制作者在制作过程中考虑了实用性，那么这个东西就不是艺术品”填补了空缺。正因为他们制作出来的东西不是艺术品了，所以他们就不能被称为艺术家。
