标题: [求助]请教GWD_1几道题~~~

GWD1-Q17:

The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic（自然音阶的） musical scale was developed and used thousands of years before it was adopted by Western musicians.

Which of the following, if true, most strongly supports the hypothesis?

Bone flutes were probably the only musical instrument made by Neanderthals.
No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.
The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.
Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.

为什么为什么选E嘞，文章中哪有cave-bear leg呢？新概念，排除

GWD1-Q39:

Which of the following most logically completes the passage below?

Heavy rains during Centralia’s corn planting season prevented some farmers there from planting corn. It is now the planting season for soybeans, another of Centralia’s principal crops, and those fields originally intended for corn are dry enough for planting. Nonetheless, even though soybean prices are unusually high at present, the farmers will leave most of these fields empty rather than plant them with soybeans, since ‗‗‗‗‗‗.

the extensive rains have led to an increase in the price of corn
some Centralian farmers anticipate serious financial losses due to the extremely wet spring planting season
chemicals that were used to prepare the fields for corn planting would stunt the growth of soybeans
the majority of Centralia’s corn farmers were able to plant corn as they had intended, despite the wet planting season
many Centralian farmers grow both corn and soybeans

B为何不对呢？

GWD1-Q40:

Until now, only injectable vaccines（疫苗） against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal（鼻的） spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.

Which of the following is an assumption on which the argument depends?

Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
The injectable vaccine is affordable for all adults.
Adults do not contract influenza primarily from children who have influenza.
The nasal spray vaccine is not effective when administered to adults.

为何选D?

第一题，科学家发现了一个笛子，但是只有7音阶中3到6的部分，但科学家仍然得出7音阶存在了很久。唯一可以support的就是E。说明制造笛子的那个材料是足够造到7个音阶的。

第二题，文中并没有说下雨对S不好，只说下雨对Corn不好。所以由于下雨引起的损失应该是corn，可是现在讨论的是为什么不种S。

第三题，如果小孩会把病传染给大人的话，那就需要给小孩接种疫苗。和文中的结论相悖
