The author believes there is a liquid water ocean beneath Pluto's surface.

• A. Cannot tell
• B. True
• C. Not stated
• D. False

Answer: (B)

The key idea here is distinguishing what the author actually believes from what is merely suggested or possible. If the text directly states that the author believes there is a liquid water ocean beneath Pluto’s surface, then the statement matches the author’s stance and is true. That explicit belief means you’re judging the author’s position, not interpreting tentative evidence or likelihood. If the author only says the ocean is possible or is supported by some data, you’d be looking at not stated or cannot tell instead. Since the given answer is true, the passage must contain language that clearly conveys the author’s belief in a subsurface liquid water ocean on Pluto.
