问一道费费题,大家帮忙看下,谢了!

82. Every photograph, because it involves the light rays that something emits hitting film, must in some obvious sense be true. But because it could always have been made to show things differently than it does, it cannot express the whole truth and, in that sense, is false. Therefore, nothing can ever be definitively proved with a photograph.

Which one of the following is an assumption that would permit the conclusion above to be properly drawn?

A.    Whatever is false in the sense that it cannot express the whole truth cannot furnish definitive proof.
B.    The whole truth cannot be known.
C.    It is not possible to determine the truthfulness of a photograph in any sense.
D.    It is possible to use a photograph as corroborative evidence if there is additional evidence establishing the truth about the scene photographed.
E.    If something is being photographed, then it is possible to prove definitively the truth about it.
答案是A没懂题目意思。。谁能帮忙分析一下

This is a suffient assumption question.  A sufficient

assumption would allow the conclusion to be properly drawn.

The conclusion of the stimulus is: nothing can ever be

definitively proven by a photo or a photo cannot prove anything

definitively.

The premises:
A photo always shows things differently from what they are, so it

cannot express the whole truth, so in that sense, a photo is

false.

The logic chain is:
Photo shows things differently --> Photo cannot express the whole

truth --> Photo is false --> Conclusion: Photo cannot prove

anything definitively.

There are three triggers 1) Photo shows things differently; 2)

Photo cannot express the whole truth; 3) Photo is false; to lead

to the conclusion - Photo cannot prove anything definitively

Answer choice A correctly picked the second trigger for the

conclusion to be drawn.

For sufficient assumptions, the correct answer simply links a

trigger with the conclusion of the argument . . .
