A brief reading of the sentences tells us that the paragraph is about Chinese business schools and how they stand in comparison to their western counterparts. 2 mentions that thought they have a similar outlook, Chinese business schools have a different curriculum and are also different in what they have to offer. 1, 4, and 5 further talk about the peculiarity of the Chinese schools. 3, however, runs tangent to the discussion. It shifts the focus from Chinese schools and describes western schools. Hence, 3 is out of the context here.
