我同意本文讲的不是disagreement,所以E不对。但是C "providing an explanation for unexpected findings"就对吗?通篇讲的是超过一个解释和意见。
我觉得A是最准确的,“describing a resource and indicating various methods used to study it”,首先文中讲了 IT 是一个 resource, 其次接下来各方意见 - some economists, Proponents of IT, some observers and Resource-based theory 次第登场,只是研究方法不同。
