The correct option is E As a result, everyone loses in the long run.
The passage explains the kind of differences that exist between the components in the supply chain, (ie. production to distribution to consumer). The nature of the differences results in a system lacking commitment on the part of the components, and lacking transparency. The para is best closed with the option that points to the logical result of such a situation – that is provided in choice E 'everyone loses in the long run'. Choice A is inappropriate since, in 'deal-making', the customer would have his own satisfaction in mind. Choice B brings in circumstances that would follow in continuation. Choice C brings in a thought contrary to the tone of the paragraph Choice D is not relevant to the content of the paragraph. Hence choice (E) is the answer.
