Typical must be true question
P1: If the needle on an industrial sewing machine becomes badly worn, the article being sewn can be ruined.
P2: People who operate the sewing machines monitor the needles and replace those that begin to wear out.
P3: Industrial sewing operations are becoming increasingly automated, and it would be inefficient for a factory to hire people for the only purpose of monitoring needles.
C: a sophisticated new acoustic device that detects wear in sewing machine needles is expected to become standard equipment in the automated apparel factories of the future.
Core of the argument :
People in traditional apparel industry would replace the needle vs Automated apparel industry, since it won't be efficient to hire the people to monitor the the needle, so an new acoustic devices to detect wear needle would be standard equipment.
OK, so if we need " monitor " for the wear needle, it must be true that the without monitoring, we neither can not " predict " nor " detect " it.
A. It is not necessary to be either less frequently or more frequently, as long as a worn out case happened, we really need monitor it and detect it.
B. So ? It is not necessary to be true. We are talking about a intangible trend must be happened due to the characteristics.
C. even if traditional factories " do " use it, it would not really relevant whether the device could be the standpoint or not.
D. Exactly as what we predicted. Its unpredictable, and that's why we need to monitor it.
E. of the scope. |
