When planning a research paper, secondary questions are

"Secondary sources were created by someone who did not experience first-hand or participate in the events or conditions you're researching. For a historical research project, secondary sources are generally scholarly books and articles. A secondary source interprets and analyzes primary sources."

When planning a research paper, secondary questions are questions that compliment the main question and objective, and help guide the research.

Explanation:

Secondary questions derive from the main research question, they are usually more specific and concrete, therefore they serve as a guide in the research, especially in the methodological phase.

the correct answer is a "it describes nora and mrs. linde's relationship". opcions b and d are not related to the content of the passage in any way. option c could be appropiate but it does not fully capture the effect of the dialogue, while option a is quite appropiate, since the dialogue not only exemplifies the relationship between the characters, but it also captures the effect in the excerpt. we get to know that mrs linde bosses around and already knows nora.
