Select the correct relative pronoun in a prepositional phrase:
'The symposium, during ______ several keynote speakers addressed climate displacement, concluded on Friday.'
Answer and explanation
Correct answer: D. which
- Step 1: In non-defining relative clauses, relative pronouns following prepositions ('during...') referring to an event or inanimate noun must be 'which'.
- Step 2: 'The symposium, during which...' is grammatically standard.
Answer
which.
Why not the others: 'where' cannot be preceded by the preposition 'during'; 'that' can never be governed by a preposition in relative clauses; 'whom' refers only to people.
