Difficulty: MediumPrepositions and Prepositional Phrases

Which preposition correctly completes the sentence below?

Answer:The continuous discharge of untreated industrial waste into the river proved detrimental 【to】 the survival of aquatic life in the region.

Answer

The preposition 'to' correctly completes the sentence because the adjective 'detrimental' takes the dependent preposition 'to'.
The adjective 'detrimental' strictly requires the dependent preposition 'to' when indicating the object or entity that suffers harm.

Step-by-Step Solution

1
Identify the key adjective governing the preposition in the sentence.
The word 'detrimental' is an adjective that requires a specific dependent preposition when connecting to its complement ('the survival of aquatic life').
In standard English grammar, specific adjectives govern fixed prepositional complements.
2
Determine the correct dependent preposition for 'detrimental'.
The adjective 'detrimental' correctly collocates with 'to' (detrimental to).
Substitutions such as 'for', 'with', or 'against' are grammatically incorrect collocations in formal English.
