Select the verb that correctly completes the collocation denoting severe disruption:

Unregulated commercial overfishing threatens to ________ havoc on the fragile coral reef ecosystems of Southeast Asia.

Answer and explanation

Correct answer: D. wreak

Answer: wreak. Why not the others: While 'cause havoc' is increasingly heard in casual speech, 'wreak havoc' is the gold standard formal collocation in academic examinations; 'inflict havoc' and 'generate havoc' are non-standard.
  1. Step 1: Identify the fixed idiom with 'havoc': the traditional, highly standard collocation is 'wreak havoc' (meaning to cause widespread destruction or devastation).
  2. Step 2: The verb 'wreak' exclusively pairs with 'havoc' in this idiomatic context.
