152. Mouth cancer is a danger for people who rarely brush their teeth. In order to achieve early detection of

describing how to perform weekly self-examinations of the mouth for lumps.

Which of the following, if true, is the best criticism of the pamphlet as a method of achieving the public health
officials’ goal?
(A) Many dental diseases produce symptoms that cannot be detected in a weekly self-examination.
(B) Once mouth cancer has been detected, the effectiveness of treatment can vary from person to person.
(C) The pamphlet was sent to all town residents, including those individuals who brush their teeth regularly.
(D) Mouth cancer is much more common in adults than in children.
(E) People who rarely brush their teeth are unlikely to perform a weekly examination of their mouth.
answer:e
what i wanna ask is that why the answer a is wrong?just as a has said, because many dental diseases produce symptoms that cannot be detected in a weekly self-examination, then we can think that method is not usrful.
please give me a direction, thank u.
people who don't often brush their teeth is more likely to contract mouth caner.
In order to help these people early detect mouth cancer (which is the intention of the government), the government sends pamphlets to teach them how to find lumps in mouth by self-examination (which is the action conducted by the government to achieve its intention).
The effectiveness of government's sending pamphlets presumes that the government's intention must be achieved by its action aiming at that intention.
