一道bf难题

大家好, 我实在找不到下题的连接, 所以re-post 一下, 希望大家讨论:

More and more computer programs that provide solutions to mathematical problems in engineering are being produced, and it is thus increasingly unnecessary for practicing engineers to have a thorough understanding of fundamental mathematical principles. Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles, so that space in the engineering curriculum will be available for other important subjects.

The two portions in boldface play which of the following roles?  

(A) The first is the second-premise that the argument includes; the second is the conclusion that could be drawn from this passage.
(B) The first is the fact that is necessary for this argument; the second is the conclusion that must be drawn from this passage.
(C) The first is the part of premise that the argument includes; the second is the inference that could be drawn from this passage.
(D) The first is the part of evidence that supports this argument; the second is the inference that could be drawn from this passage.
(E) The first is the first conclusion in this argument; the second is the second conclusion in this argument.

我觉得C, 但是A 看看也对.  愿高手指点.

还不是高手，切磋一把

结论是，“ less emphasis should be placed on mathematical principles”

“consequently”表明前面的bf是premise,“so that”表明后面的bf是引申

A说first是第二premise,这个从何说起呢？
