Questions 16-17 Henry: Some scientists explain the dance of honeybees as the means by which honeybees communicate the location of whatever food source they have just visited to other members of the hive. But honeybees do not need so complicated a mechanism to communicate that information. Forager honeybees returning to their hive simply leave a scent trail from the food source they have just visited. There must therefore be some other explanation for the honeybees’ dance.     Winifred: not necessarily. Most animals have several ways of accomplishing critical tasks. Bees of some species can navigate using either the position of the Sun or the memory of landmarks. Similarly, for honeybees, scent trails are a supplementary not an exclusive means of communicating.

16. The point at issue between Henry and Winifred is whether (A) theories of animal behavior can be established on the basis of evidence about only one species of animal (B) there is more than one valid explanation for the dance of honeybees. (C) Honeybees communicate the location of food sources through their dance. (D) The honeybee is the only species of bee that is capable of communicating navigational information to other hive members(E) The honeybee’s sense of smell plays a role in its foraging strategies.

我有错了主题提：答案是c 我选了b 。 我无法分清为什么b不对。 我早两者分歧的方法是这样的。我找到前一个人的结论，后者反对的内容。 我们看下一道题答案是c我选了a ，也是错掉了 。但是我不知道我这种方法错在哪里了？？ 请指教，若非如此 我将继续错下去。

16. Motorcoach driver: Professional drivers spend much more time driving, on average, than do other people and hence are more competent drivers that are other, less experienced drivers. Therefore, the speed limit onmajor highways should not be reduced, because that action would have the undesirable effect of forcing some people who are now both law-abiding and competent drivers to break the law. Police officer: All drivers can drive within the legal speed limit if they wish, so it is not true to say that reducing the speed limit would be the cause of such illegal behavior.

The point at issue between the motorcoach driver and police officer is whether (A) it would be desirable to reduce the speed limit on major highway (B) professional drivers will drive within the legal speed limit if that limit is reduced (C) reducing the speed limit on major highways would cause some professional drivers to break the law (D) professional drivers are more competent drivers than are other less experienced drivers (E) all drivers wish to drive within the speed limit

再看一道题 同样是两者矛盾体，又错了。答案是d我选了c 思路如下。我发现我把两个人的结论都找出来了，但是答案是后一个人的结论。 难道这样的题是这样子做法-看后者的结论？？？？

Questions 13-14 Yolanda: Gaining access to computers without authorization and manipulating the data and programs they contain is comparable to joyriding in stolen cars; both involve breaking into private property and treating it recklessly. Joyriding, however, is the more dangerous crime because it physically endangers people, whereas only intellectual property is harmed in the case of computer crimes. Arjun: I disagree! For example, unauthorized use of medical records systems in hospitals could damage data systems on which human lives depend, and therefore computer crimes also cause physical harm to people.

13. An issue in dispute between Yolanda and Arjun is (A) whether joyriding physically endangers human lives
(B) whether the unauthorized manipulation of computer data involves damage to private property (C) whether damage to physical property is more criminal than damage to intellectual property (D) whether the unauthorized use of computers is as dangerous to people as is joyriding
(E) whether treating private property recklessly is ever a dangerous crime

再错！答案ｄ　我ａ　。找不到方向了，　啊！

Questions 21-22 Wirth: All efforts to identify a gene responsible for predisposing people to manic-depression have failed. In fact, nearly all researchers now agree that there is no "manic-depression gene." Therefore, if these researchers are right, any claim that some people are genetically predisposed to manic-depression is simply false. Chang: I do not dispute your evidence, but I take issue with your conclusion. Many of the researchers you refer to have found evidence that a set of several genes is involved and that complex interactions among these genes produce a predisposition to manic-depression.

21. The point at issue between Wirth and Chang is whether (A) efforts to identify a gene or set of several genes responsible for predisposing people to manic-depression
have all failed (B) it is likely that researchers will ever be able to find a single gene that predisposes people to manic-depression (C) nearly all researchers now agree that there is no manic-depression gene(D) current research supports the claim that no one is genetically predisposed to manic-depression (E) the efforts made to find a gene that can produce a predisposition to manic-depression were thorough

for 16 and 13, your choice is agreement rather than disagreement.

21 answer D  see these "I do not dispute your evidence, but I take issue with your conclusion"  can you find the conclusion above ?
