Argument Construction
Situation Irradiation kills bacteria but it also lowers the amount of nutrients—including vitamin
B1—in foods. Proponents try to dismiss this concern by arguing that cooking destroys
B1 as well. Th at point is said to be misleading.
Reasoning Which option most logically completes the argument? For the proponents’ claim to be
misleading it needs to be suggesting something about irradiation that is false. By stating
that irradiation destroys no more B1 than cooking does, the proponent seems to be
suggesting that any food that is going to be cooked might as well be irradiated because it
will end up with the same amount of B1 either way. But if the eff ects of radiation and
cooking combine to destroy more B1 than cooking or irradiation alone would, then the
proponents’ claim suggests something that is false.
A Th is might make the assurances of the proponents less credible but it does not make their claim
misleading.
B Nothing about the proponents’ claim suggests that the only eff ect irradiation has is to kill
bacteria.
C Th e fact that cooking and irradiation have diff erent purposes does not indicate that the
proponents’ claim suggests something that is false.
D If anything, this strengthens the proponents’ point by minimizing the relative damage caused by
irradiation.
E Correct. Th is option most logically completes the argument.
Th e correct answer is E.

E,说当同时采用两者时，损失的VB1是两者分别损失的量之和。在破坏VB1这一点上，两者是在同一时点上进行的，对于这个合二为一的整体动作而言，二者比较没有意义，因为两个个体的比较是要比出谁好谁坏，但比较的结果对于整体效果而言，是没有任何意义的，因为无论是一好一坏，还是二者一样，整体都是二者的和。在这一点上，比较没有了意义，所以就是misleading
