Question

when conducting a poll, researchers must account for a number of variables that can affect the results. for example, many people may choose not to respond, meaning that the results might only represent a small fraction of the intended sample of participants. also, some participants may provide the response that they believe is most socially acceptable, instead of giving their true opinion. lastly, the specific language used in survey questions can influence responses: even slight changes in wording can produce substantially different results. taken together, these factors suggest that ______
which choice most logically completes the text?
choose 1 answer:
a polls may offer estimations, rather than perfect representations, of public opinion.
b it should be mandatory for people to respond to polls to ensure that the results are representative of peoples true opinions.
c polls are unreliable sources of information, as they often misrepresent public opinion.
d more often than not, survey respondents provide responses that do not reflect their true opinions.

Explanation:

• Option A: The text lists factors like non - response, socially acceptable responses, and language influence. These factors mean polls can't perfectly represent public opinion but can offer estimates.
• Option B: The text doesn't suggest making responses mandatory. It just lists existing issues.
• Option C: Saying polls are "unreliable sources" is too extreme. The text shows there are limitations but not that they are completely unreliable.
• Option D: While some participants may not give true opinions, this is only one of the factors mentioned. The overall conclusion should be about the polls' representation (estimation vs. perfect representation) rather than just focusing on this one aspect.

Answer:

A. polls may offer estimations, rather than perfect representations, of public opinion.
