The passengers were angry ______ the airline staff about the delay. A. on B. about C. with D. towards

GATE 2019 · General Aptitude · Prepositions · medium

Answer: C. with

1. Identify the target of the anger: The blank precedes 'the airline staff', who are people. When 'angry' is directed at people, the standard preposition is 'with'.
2. Eliminate other options: 'Angry on' is not a standard collocation. 'Angry about' fits reasons/situations, not people as targets here. 'Angry towards' implies direction of movement rather than an emotional attitude in standard formal English.
3. Confirm answer: 'The passengers were angry with the airline staff about the delay.' — grammatically correct and idiomatic.
