Which of the following most logically completes the argument?

When people engage in activities that help others,their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because.

A.in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do.

B.the number of young adults who do regular volunteer work is on the increase

C.the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild.

D.it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life.

Some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives.

However, that statistic would be what we would expect even if volunteering does not boost longevity, because

最后一句话的意思是：除了做志愿者工作，还有其他原因导致人们长寿。

A选项：在调查的社区里，女人比男人更倾向去做志愿者工作，女人比男人长寿。因为题干最后一句话已经说了不是做志愿者导致长寿，所以A选项的隐含意思还有其他原因一样造成人长寿。

Excavations of the Roman city of Sepphoris
have uncovered numerous detailed mosaics depicting several readily identifiable animal species:a hare, a partridge, and various Mediterranean fish.Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.
Which of the following is an assumption on which the argument depends?

A.The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.

B.There is no single region to which all the species depicted in the Sepphoris mosaics are native.

C.No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.

D.All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

E.There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

答案是A。最后一句“结果也是像我们期望的那样，即使志愿者不会使人长寿”。这里的结果是指“做志愿者导致长寿”。所以可以看成“做志愿者导致长寿这个结果也是像我们期望的那样，即使志愿者不会使人长寿”因为“做志愿者女比男多，and女本来就比男长寿
