Attempted by 105 students.
Show answer & explanation
Correct answer: A
Answer: "revolves" — correct.
Explanation: "revolves around" is a standard collocation meaning "is centered on" or "focuses on." It correctly conveys that the business model is built around the idea of trust.
Why "revolves" is correct: it naturally pairs with "around" to indicate centrality (e.g., "X revolves around Y" = X is centered on Y).
Why "plays" is incorrect: "plays" does not collocate with "around" to mean "is centered on." You could use "plays a role in" but that changes the structure and nuance.
Why "sinks" is incorrect: "sinks" implies falling or submerging and does not express being centered on something.
Why "bursts" is incorrect: "bursts" suggests exploding or breaking and is not used to mean "is centered on."
Alternative correct phrasings: "is centered on", "is built around", "focuses on".
