The following sentence has two blanks. Choose the most suitable set of prepositions from the given options to fill in the blanks and complete the sentence meaningfully: She was reprimanded _____ being late and warned _____ further delays.
for, against
The sentence has two blanks, each governed by a different verb, so each preposition must match its own verb's fixed collocation.
Blank 1 follows 'reprimanded'. The standard pattern is 'reprimand someone for (a fault)', so 'for being late' correctly states the reason for the rebuke.
Blank 2 follows 'warned'. To caution someone not to do something, English uses 'warn against (doing something)', so 'warned against further delays' fits.
Combining them yields 'reprimanded for being late and warned against further delays', which reads idiomatically.
'at, of' and 'on, for' break the 'reprimand for' collocation, and 'from, despite' pairs a source-preposition and a concession word that neither verb takes here.
Only the pair that gives both 'reprimanded for' and 'warned against' is correct.
Hence the right set of prepositions is for, against.
