Question

Quizplus · Accepted Answer

Phone books only list landline phone numbers, so they do not include wireless numbers. Additionally, phone books may not be updated frequently enough to capture households that move from one area to another, leading to an insufficient sampling frame. There is also a possibility that there may be non-coverage areas that are not listed in the phone book. Therefore, all of the choices (A-D) are correct.
