11. If the needle on an industrial sewing machine becomes badly worn, the article being sewn can be ruined. In traditional apparel factories, the people who operate the sewing machines monitor the needles and replace those that begin to wear out. 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. Therefore 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.
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.

有些没有感觉，怎么同RATE有关系？

16. Researchers in South Australia estimate changes in shark populations inhabiting local waters by monitoring what is termed the "catch per unit effort" (CPUE). The CPUE for any species of shark is the number of those sharks that commercial shark-fishing boats catch per hour for each kilometer of gill net set out in the water. Since 1973 the CPUE for a particular species of shark has remained fairly constant. Therefore, the population of that species in the waters around South Australia must be at approximately its 1973 level.
Which one of the following, if true, most seriously weakens the argument?
(A) The waters around South Australia are the only area in the world where that particular species of shark is found
(B) The sharks that are the most profitable to catch are those that tend to remain in the same area of ocean year after year and not migrate far from where they were born.
(C) A significant threat to shark populations, in addition to commercial shark fishing is "incidental mortality" that results from catching sharks in nets intended for other fish.
(D) Most of the quotas designed to protect shark populations limit the tonnage of sharks that can be taken and not the number of individual sharks.
(E) Since 1980 commercial shark-fishing boats have used sophisticated electronic equipment that enables them to locate sharks with greater accuracy.
KEY ： E
结论是因为CPUE没有变，所以SHARK的数量没有变。我怎么觉得C不错，因为C是CPUE没有统计到的情况，而可能降低SHARK的数量。E导致了CPUE变大，否认了文章的前提/条件。

11. Explained before. If the needle is worn out at a predictable rate, you do not need to monitor it. You can simply replace the needle when it is expected to be replaced.

16. C does give a factor other than what is mentioned in the passage. However, C does not tell you if IM changes over time or remains constant. In another word, you have no clue what the IM has been during this period. How can you use C to WEAKEN the conclusion?

E points out the changes in CPUE. For example, they could catch 3 out of 100 sharks in an hour in 1973 while they can catch 30 out of q00 sharks in an hour with a refined technology.

11题我今天也遇到了，你解释的D很有道理。当为什么E不对呢？“new acoustic device ”很容易让人和“noise"联系起来。

我觉得答案D，作为“assumption"更合适，而E似乎更有support的意思。
