閱讀TPO14:Children and Advertising - 英檢

各位板友好

想請問一題

原文: Certainly, rational appeals in advertising aimed at children
are limited, as most advertisements use emotional and indirect
appeals to psychological states or associations.

8. Which of the sentences below best expresses the essential
information in the highlighted sentence in the passage?

(A) Rational appeals in advertising are certainly limited by
children's emotional immaturity and the indirect nature
of their associations.

(B) Indirect appeals to children's psychological states or
associations can limit the effectiveness of rational
appeals in advertising.

(C) Rational appeals play a much smaller role in advertisements
for children than emotional appeals and psychological associations do.

(D) Rational appeals in advertising aimed at children should
certainly be limited until the children are emotionally and
psychologically ready.

答案是(C)

看了答案之後還是覺得怪怪的
我對原文的理解是
因為rational appeals 有限制，所以才要用emotional appeals。
所以我感覺不出來有比較的意思(還是我搞錯意思了@@)
而且其實我不懂原文第二句的 as 是什麼意思?

可以麻煩板上的高手幫忙解答一下嗎?
感恩~!!
