It is widely assumed that people need to engage in intellectual activities such as solving crossword puzzles or mathematics problems in order to maintain mental sharpness as they age. In fact, however, simply talking to other people—that is, participating in social interaction, which engages many mental and perceptual skills—suffices. Evidence to this effect comes from a study showing that the more social contact people report, the better their mental skills.

Which of the following, if true, most seriously weakens the force of the evidence cited?

Increased use of incineration is sometimes advocated as a safe way to dispose of chemical waste. But opponents of incineration point to the 40 incidents involving unexpected releases of dangerous chemical agents that were reported just last year at two existing incinerators commissioned to destroy a quantity of chemical waste material. Since designs for proposed new incinerators include no additional means of preventing such releases, leaks will only become more prevalent if use of incineration increases.

Which of the following, if true, most seriously weakens the argument?
驳斥题。感觉A选项无关。误选D。 对于CR驳斥的题目，为什么有些正确的选项读出的是无关的感觉呢？是没有读懂句子还是其他原因？ 望老师指点一下，谢谢~

Pharmacists recently conducted a study with respect to the reasons their customers purchased eye drops to soothe eye dryness.

Senator Janice White is quietly lobbying to become chairman of one of the Senate’s most prestigious committees. However, that post currently belongs to Senator Dan Smith. If Senator Smith already has twenty senators committed to his continued chairmanship of the committee, then Senator White will consider another committee. If Senator Smith does not have that much support lined up yet, then Senator White will study Senator Smith’s past committee voting record for inconsistent and unpopular votes. If Senator White finds that Smith’s voting record is out of favor with today’s voter and publicizes it, then her chances of capturing the chairmanship would be increased, and she would publicly announce her interest in the chairmanship. If Senator Smith’s committee voting record is in keeping with current public sentiment and contains no inconsistencies, then Senator White will focus her attention on another committee chairmanship.
Based upon the information provided in the passage, which one of the following statements must be false?

So, the new coaching position will be eliminated.
The conclusion stated in the passage above is properly drawn if which one of the following assumptions is made?

For a recent play performance, the ticket prices were $25 per adult and $15 per child.  A total of 500 tickets were sold for the performance.  How many of the tickets sold were for adults?
(1)     Revenue from ticket sales for this performance totaled $10,500.
(2)     The average (arithmetic mean) price per ticket sold was $21.
老师，上次讲了两道DS，一道是邮票的，涉及到实际问题，且某一单价为0.15，数值特殊，第一个条件只能得出唯一解，所以选A。第二道也是门票问题，根据条件1不能得出唯一解，所以选C。这个题条件1和2的性质是一样的，其中任一条件与题干都可以列出两个方程，即X+Y=500和25X+15Y=10500，我想问老师根据这两个式子就可以确定出唯一解吗？感觉被这种类型的题搞蒙了 一、Joanna bought only $0.15 stamps and $0.29 stamps. How many $0.15 stamps did she buy? (1) She bought $4.40 worth of stamps. (2) She bought an equal number of $0.15 stamps and $0.29 stamps. 二、For a certain play performance, adults' tickets were sold for $12 each and children's tickets were sold for $8 each. How many children's tickets were sold for the performance? (1) The total revenue from the sale of adults' and children's tickets for the performance was $5,040. (2) The number of adults' tickets sold for the performance was 1/3 the total number of adults' and children's tickets sold for the performance.
