Coral reefs provide critical habitat for thousands of marine species, yet they face unprecedented threats from rising ocean temperatures. Marine biologist Dr. James Chen has documented how even modest temperature increases can trigger coral bleaching events. His research demonstrates that when water temperatures remain elevated for extended periods, corals expel the symbiotic algae living in their tissues, causing the corals to turn white and become vulnerable to disease. Chen emphasizes that while some corals can recover if conditions improve quickly, prolonged stress often proves fatal.

How to score it
- Predict your own word from the sentence's cue before you read the choices — then match.
- Find the cue: same sentence (easy), the next sentence (medium), or a contrast word like “but/however” that flips the meaning (hard).
- Demand precision, not vibes — the SAT wants the exactly-right sense, not a word that's merely close.
Common traps
- Opposite-direction word — right topic, wrong direction.
- A word that's true in general but ignores the sentence's specific cue.
- A familiar synonym that doesn't fit this sentence's sense.
