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.
