Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally. The Egyptians, however, did not discover leavened bread until about 3000 B.C. That discovery roughly coincided with the introduction of a wheat variety that was preferable to previous varieties because its edible kernel could be removed from the husk without first toasting the grain.

Which of the following, if true, provides the strongest evidence that the two developments were causally related?

正确答案: C

39. GWD26-Q39
Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally. The Egyptians, however, did not discover leavened bread until about 3000 B. C. That discovery roughly coincided with the introduction of a wheat variety that was preferable to previous varieties because its edible kernel could be removed from the husk without first toasting the grain.

Which of the following, if true, provides the strongest evidence that the two developments were causally related?
A.    Even after the ancient Egyptians discovered leavened bread and the techniques
for reliably producing it were well known, unleavened bread continued to be
widely consumed.
B.    Only when the Egyptians stopped the practice grain were their stone-
lined grain-toasting pits available for baking bread.
C.    Heating a wheat kernel destroys its gluten, a protein that must be present in order
for yeast to leaven bread dough.
D.    The new variety of wheat, which had a more delicate flavor because it was not
toasted, was reserved for the consumption of high officials when it first began
to be grown.
E.    Because the husk of the new variety of wheat was more easily removed, flour
Made from it required less effort to produce.

我虽然看不懂题目,但是我用我自己的方法能推出C为选项
我觉得文章作者期望的结果是想把wheat和leaven bread扯上关系,然后看看选项,只有C符合

我觉得吧...文章说了两件事;1.leaven bread的发现 2.introduction of wheat variety;文章要加强的点是:1和2casually related,即两件事情有关系,ABCDE选项,只有c能说明两件事情是有关系的;heating会destroy gluten,而没有gluten就没有leaven,introduction of wheat variety可以不用heat,所以gluten也不会是被destroy了,因此leaven就可以被发现了;   不知道对不对哦·····希望能有所帮助····
