19: Sonya: The government of Copeland is raising the cigarette tax. Copeland’s cigarette prices will still be reasonably low, so cigarette consumption will probably not be affected much. Consequently, government revenue from the tax will increase.

Raoul: True, smoking is unlikely to decrease, because Copeland’s cigarette prices will still not be high. They will, however, no longer be the lowest in the region, so we might begin to see substantial illegal sales of smuggled cigarettes in Copeland.

Raoul responds to Sonya’s argument by doing which of the following?

A: Questioning the support for Sonya’s conclusion by distinguishing carefully between No change and no decrease

B: calling Sonya’s conclusion into question by pointing to a possible effect of a certain change.

C: Arguing that Sonya’s conclusion would be better supported if Sonya could cite a precedent for what she predicts will happen.

D: showing that a cause that Sonya claims will be producing a certain effect is not the only cause that could produce that effect

E: pointing out that a certain initiative is not bold enough to have the predicts it will have

16: In recent years, networks of fiber-optic cable have been replacing electrical wire for transmitting telecommunications signals. Signals running through fiber-optic cables deteriorate, and so the signals must be run through a piece of equipment called a regenerator before being transmitted father. Light-Line is the leading manufacturer of signal regenerators. Therefore, Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.

Which of the following, if true, casts the most doubt on the prediction about light-ling’s prospects?

A: Telecommunications signals sent along electrical wires can travel much farther than signals transmitted through fiber-optic before needing to be regenerated.

B: Expanding its production of regenerators will require Light-line to spend proportionately more on labor and materials.

C: The volume of signals that a fiber-optic cable can carry is several thousand times greater than the volume that can be carried by an electrical wire of similar size.

D: There are technologies that enable telecommunications signals to be transmitted without either wire or fiber-optic cable.

E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.

28-28: Which of the following most logically completes the argument?

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.

A: histidine is found in all parts of the plant – roots, stem, leaves, and flowers

B: the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids

C: others of the closely related group of plants are also found to produce histidine in large quantities

D: cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic

E: the concentration of histidine in the growing herb declines as the plant approaches maturity

我的答案：a e c

选d,有一个逻辑错误:题目说那个herb能产生一种东东,让毒素失效.可是他没说那个东东释放到了外面土壤里啊,很可能它就只停留在植物体内发挥作用啊,很多生长素就是这样的,所以也不会对土壤产生影响.

c我觉得是很好的加强啊,一种herb有了histidine,就能帮助它生存,那么其他也能生存的植物也都有那个东东,直接加强结论啊.
