Answer:
A. an in-depth study of what moviegoers liked and disliked about a new theater
Explanation:
Focused interviews, also known as semi structured interviews, are a research tool used to get qualitative in-depth information from a small sample of respondents. The main advantage of this tool is that when applied by a trained interviewer, it allows the researcher to gather in-depth explanations and points of view from the respondents. The goal with these is not to make generalizations to a wider population, but to understand the respondent's points of view on a particular subject. Since it requires more time and resources to set a focused interview than to give out surveys, samples can't be too large, making this tools ineffective for statewide or nationwide studies. Instead, asking moviegoers about what they like and didn't like from the theater is ideal for these kind of studies, as the samples can be small and you will not only find what they liked or disliked but also why.
