Answer

commensurate with
In standard written English, the adjective 'commensurate' idiomatically pairs with the preposition 'with' when indicating that something is proportionate or corresponding in size or degree.

Step-by-Step Solution

1
Identify the target adjective in the underlined phrase.
The adjective is 'commensurate', which requires a specific idiomatic preposition when describing proportional relationships.
Standard written English dictates fixed prepositional pairings for specific adjectives.

The standard idiomatic expression is 'commensurate with', meaning corresponding in size, degree, or extent.
Prepositions such as 'to', 'for', and 'towards' violate standard English usage rules when following 'commensurate'.
