这道题为什么不用题干里提到的做法来做？

NO.PZ201602060100002003 问题如下 3. Baseon Abay’s criterithe business segment best suitefor vestiture is: A.mecequipment. B.power aninstrial. C.automation equipment. B is correct.The Power anInstrisegment hthe lowest EBIT margins but uses about 31 percent of the capitemploye Further, Power anInstrial’s proportion of the capitexpentures hincreasefrom 32 percent to 36 percent over the three years. Its capitintensity only looketo get worse, the segment’s percentage of totcapitexpentures whigher thits percentage of totcapitin eaof the three years. If Abis consiring vesting segments th not earn sufficient returns on capitemploye this segment is most suitable.解析考点是capitallocation cision。首先计算部门的capEX%/Asset%，Power部门2007和2009年的capEX%/Asset%分别是1.07和1.13，说明公司对Power部门在加速投资，capEX%从2007年的32%增加到了2009年的36%，也就是Power部门的capitexpentures占了公司总capitexpentures的约1/3，但是Power部门的EBITmargin是三个部门最低的，因此如果公司要选择一个部门降低投资，Power部门是最合适的。 只看Segment EBIT margins，直接干掉那个最低的，不考虑capEX%/Asset%，是不是也可以？capEX%/Asset% 1，说明在加速投资，capEX%/Asset% 1，说明没有加速。其实不用考虑这么多，题目只问 vestiture，就考察收益率就行，对吧？
