Passage: "For decades, coral reefs were studied mainly for their biodiversity. Newer research, however, treats them as economic infrastructure — natural breakwaters that shield coastlines and sustain fisheries worth billions." What is the main point?

1. What skill does the approved sample question test?
act
The structure is old-view/new-view, pivoting on "however." The main point is the shift itself: reefs are now studied as economic infrastructure, not just for biodiversity. A correct main-idea answer captures that change in framing rather than restating only the old view (biodiversity) or only one example (breakwaters). ACT reading rewards the choice that captures the passage's overall claim, not a single detail.
2. What mistake should you watch for in Command of evidence?
Choosing an answer that sounds right but is unsupported
StudyVector stores common mistake patterns so the next attempt can repair the specific error rather than restart the whole course.
3. What should happen after a missed point?
Review the explanation, name the mistake, then answer a similar question while the correction is fresh.
The page feeds the same loop as practice: attempt, feedback, repair, and return.
