Select the correct preposition combination: 'The researchers were commended ______ their dedication ______ sustainable arid-land agriculture.'
Answer and explanation
Correct answer: B. for; to
- Step 1: Recognize standard academic collocations with adjectives and verbs:
- Step 2: The verb 'commend' takes the preposition 'for' (commended for something).
- Step 3: The noun 'dedication' takes the preposition 'to' (dedication to a cause or discipline).
- Step 4: Therefore, 'commended for their dedication to' is the correct idiomatic phrase.
Answer
for; to.
Why not the others: 'on; with' is ungrammatical with 'commended' and 'dedication'; 'about; in' uses non-standard prepositions; 'with; for' reverses typical prepositional roles.
