In a survey which uses lay interviewers to interview one person about his or her health and the health of household members, the sources of error include:
a. the person with disease has had no symptoms and is not aware of the disease.
b. the respondent provides the information but the interviewer doesn’t record it or records it incorrectly.
c. the interviewer doesn’t ask the questions that he or she is instructed to ask, or asks them incorrectly.
d. the person has had symptoms and has had medical attention but does not know the name of the disease.
e. all of the above

Correct answer is (e) all of the above.

step-by-step explanation:

As for the option (a) and (d), you can't give information you don't have. When you are not aware of the diseases, you can not give information about it.

For option (b), when the interviewer did not record the information or record it incorrect, it can not be used for survey.

For option (c), when correct questions are not asked, you can't required answers for the survey.

Summation of the above will be sources of error for the survey.
