A professor explains why bird migration patterns have shifted in recent decades. She presents two contributing factors — changing temperature patterns affecting food availability, and habitat loss along traditional migration routes — and notes that researchers are still studying which factor has a larger overall effect.
Question: How does the professor organize her explanation? Answer: By presenting two distinct contributing factors in sequence, then noting the ongoing uncertainty about their relative importance — recognizing this two-factor structure is what makes the individual details easier to keep straight.
Question: What can be inferred about the current state of research on this topic? Answer: It's still ongoing and not fully settled — the professor's statement that researchers are "still studying which factor has a larger effect" implies the question isn't yet resolved, without saying so in those exact words.
