hi mm,i make the same mistake as you,but now i choose a,for we can see the question is what that proponents of resource-based theory would be likely to explain IT’s ...while the answer e changes brought about by IT cannot be detected by macroeconomic measures appear before the author mention to the resource-based theory ,so we can choose the right answer a.
i think a lot of gwd's questions have such tricks,we should read the questions more carefully,not confuse the details
选E得人混淆了Proponents of IT 和 Proponents of Resource-based theory. 文中并没有直接提到Proponents of Resource-based theory. 只提到Proponents of IT。如果没有读懂的人,只靠Proponents去定位,必上当无疑。
After reading A choice carefully, I agree A is incorrect because the literature didn't mention "effective ways to use IT", it just sugested "advantage for firms using IT", as E stated.
