Insect infestation is a danger for households in which certain standards of cleanliness are not maintained. So that householders are able to detect such infestations before they become serious enough to pose a danger, the county sanitation board has mailed a newsletter to all residents of the county, listing those signs that indicate the beginnings of an insect infestation and encouraging householders to check for such signs.

Which of the following, if true, is the best criticism of the newsletter as a means of achieving the sanitation department's goals?

Many insect infestations have certain characteristics that cannot be detected by the investigation of a householder.

Once an insect infestation is known to exist, the steps taken to eliminate such an infestation vary according to the species of insect and the locale of the infestation.

The newsletter was sent to all residents of the county, including those who maintain the standards of cleanliness that preclude the possibility of insect infestation.

Insect infestation is more common in single-family homes than it is in apartments.

People who do not maintain minimal standards of cleanliness are unlikely to inspect their homes for the signs of early insect infestation.

Please explain me how A is wrong.
Since there are many infestations cannot be detected by layman and thus there is negligible effect of the newsletter.

I got down to C and E, and E won.

Answering the question of why not A, in this question we want to weak the fact that sending a letter to every house hold (neat and unneat) will make the difference preventing the danger posed by infestations.

In my opinion the problem with A is that it is out of scope. We want to address directly to the fact that the letter wont make any difference. Be suspect on "Many" in a question as it opens the possibility that "not Many", or "some" (not all) infestations have the discrived characteristics. Such possibility creates the ideal scenario for out of scope, as many possibilities arise if some insect infestations do not have the undetectable characteristic mentioned in A, and thus are prone to be detected after the reading of the letter.

I hope you find some value in my comment.

Many insect infestations have certain characteristics that cannot be detected by the investigation of a householder. It strengthen that newsletter will do more and mroe effects on cleaning insect. As said, few household knows the location and signs of the onset of the insect. So, if newsletter used, household has bigger chance to find the insect.
