答案是题目结论成立的必要条件的assumption;答案是题目成立充分条件的justify the conclusion.

第一种很常见，第二种如下题。

100. A compelling optical illusion called the illusion of velocity and size makes objects appear to be moving more slowly the larger the objects are. Therefore, a motorist's estimate of the time available for crossing a highway with a small car approaching is bound to be lower than that it would be with a large truck approaching.

the conclusin above would be more properly drawn if it were made clear that the:
A truck's speed is assumed to be lower that the car's
B truck's speed is assumed to be the same as the car's
C truck's speed is assumed to be higher than the car's
D.mostoris's estimate of time available is assumed to be more accurate with cars approaching than with trucks approaching

E.motorist's estimate of time available is assumed to be more accurate with trucks approaching than with cars approaching
