Techniques to increase productivity in the performance of discrete

Why not A could you pls explain ?

In my opinion, Option A doesn’t work because it states that the techniques SHOULDN’T be implemented. If you read the passage carefully, it says: “although they achieve their specific goals, they’re not without drawbacks. They ‘often’ instil enough resentment in the workforce eventually to lead to a slowdown in the production process as a whole.” Often doesn’t mean all the time. Moreover, it only talks about the production process slowing down and not bringing it to a halt.

I hope this helps.

KAPLAN OFFICIAL EXPLANATION:

D

Here the author presents the consultants' ideas. Notice the paragraph uses words like often and slowdown. The correct response should not go beyond such terminology. Consultants' conclusion: Techniques to increase productivity of discrete tasks have drawbacks, even though they accomplish their specific goals. Consultants' evidence: They often instill enough resentment to lead to a slowdown in the production process as a whole.

(A) is a too sweeping a generalization, an unwarranted inference about productivity enhancement techniques. Do these techniques never work? (B) is even further out. Nowhere does the information imply that America is less competitive abroad than before. Since no geographic location is mentioned, this data could have originated in Europe. (C) projects into the future, to an extreme result. All we're told is that sometimes these techniques lead to a slowdown in the production process. (D) uses similar language (and tone) to the original paragraph and remains in scope without bringing in additional information. It is an accurate summary of the text. (E) can almost be disqualified after the first few words. Though it picks up on the negative aspects of productivity enhancement, we can infer nothing about production managers since they are never mentioned. In fact, many production managers may be ecstatic about the efforts that did pay off.­
