Answer: your question is incomplete, as you have not provided the group of answer choice, please let me assume this to be your complete question;
Cynthia is conducting a survey on the prevalence and patterns of substance abuse in her city. Which of the following problems is she likely to encounter while using this method of data collection?
a. The assumption that a person's behavior is consistent and stable.
b. The inability to sample a large number of people.
c. The assumption that surveys have to be conducted only in person.
d. Some participants may not tell the truth and instead give socially acceptable answers.
ANSWER : Option d. Some participants may not tell the truth, and instead give socially acceptable answer.
Explanation: Because substance abuse is not socially accepted, people don't always want to be identified as one who abuse any substance. This is why many people hide to abuse this, and many don't want their loved ones to know their abuse any substance.
Cynthia will not get an accurate result, because many people will deny of not abusing any substance, and many will not want to be open up on which substance their abuse the most. This study is meant to be an observational study, and not a survey study, if we wish to reduce the error in the result.
