Choose the verb that completes the standard evaluative collocation:

The newly released meteorological measurements cast serious ________ on the accuracy of previous oceanic warming projections.

Answer and explanation

Correct answer: C. doubt

Answer: doubt. Why not the others: 'cast suspicion on' implies moral guilt or criminality rather than scientific inaccuracy; 'cast disbelief' and 'cast uncertainty' are unidiomatic collocations.
  1. Step 1: Identify the fixed verb-noun collocation with 'cast': the phrase 'cast doubt on' (or 'cast doubt upon') is the standard formal idiom meaning to make something seem uncertain or questionable.
  2. Step 2: The required noun is 'doubt'.
