OG-10-55

55. 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?

(A) Some furniture is made to be placed in museums, where it will not be used by anyone.

(B) Some cabinetmakers are more concerned than others with the practical utility of the products they produce.

(C) Cabinetmakers should be more concerned with the practical utility of their products than they currently are.

(D) An object is not an art object if its maker pays attention to the object’s practical utility.

               (E) Artists are not concerned with the monetary value of their products.

题目倒不是很难，答案是D。

但是不是很明白OG的解释。

Reasoning: What assumption is made in the argument? The argument makes a general statement about all cabinetmakers and all their furniture. The assumption must also be a general statement because it is not logical to reason from a particular statement about some furniture or some cabinetmakers to a general statement about all cabinetmaking. What excludes pieces of furniture from being considered works of art? The argument states only that their usefulness must be taken into account during their creation. Therefore, the operative assumption must be that an object created with its practical use in mind cannot be a work of art.

 红线部分是不是说文中结论是针对全体的，假设条件也必须是针对全体的？之所以这么解释是不是为了排除A和B？这个题有必要考虑这么多吗？还是OG说这个还别有他意？

请大家给我点意见。

谢谢指教。

大家有没有看过别的题目用到这个技巧的？
