Which one of the following is most strongly supported by the information above?
(A) In automated apparel factories, items will be ruined by faulty needles less frequently than happens in traditional apparel factories.
(B) In the automated apparel factories of the future, each employee will perform only one type of task.
(C) Traditional apparel factories do not use any automated equipment.
(D) The needles of industrial sewing machines wear out at unpredictable rates.
(E) As sewing machine needles become worn, the noise they make becomes increasingly loud.

Hi Mike, Although I got the correct answer, i couldn't get why option E is incorrect. Waiting for reply. Regards, Fame
We want to know which of the five answer is "
most strongly supported by" the passage. In other words, what's the most justified conclusion we can draw?
We know they are bring in "
a sophisticated new acoustic device", which suggests the change in the needles will be detected via some sort of sound. But, do we know that it's a
loud sound? Or, does the worn out needle change its sound in some other way, such as a higher pitch frequency or something like that. In a way, the fact that the need a "
sophisticated" device suggests that the change in sound might be something unapparent to the ordinary ear. We certainly do not have evidence that the needles get "
increasingly loud" as they wear out. That's why
(E) cannot be correct.
Does that make sense?

Hi Mike
Can you help to explain why B is incorrect. I'm not really satisfied with all the explanation above.
B)
"
Industrial sewing operations are becoming increasingly automated, however, and it would be inefficient for a factory to hire people for the
sole purpose of monitoring needles."
==> Paraphrasing:
In the automated apparel factories of the future, each employee will perform
only one type of task.
Hence, I think B is correct
D)The needles of industrial sewing machines wear out at
unpredictable rates.
The premises just stated that "the people who operate the sewing machines monitor the needles and replace those that begin to wear out" without mentioning about the unexpected rate. It is possible that at the expected rate , we still need worker to monitor and replace the needles??
Thanks
