In this task, a passage will be given and the goal is to generate a question about temporal relations based on that passage. A temporal relation describes the relation between two things with respect to time e.g., something happens/starts/terminates/... immediately/shortly/usually/... before/after/during/... something else.
Your question should include an event, or ask about an event, and should not be a yes/no question.

Passage: In October he said Israel "must be wiped off the map", and last week said Israel was a "tumour" that should be moved to Germany or Austria -- comments that were also condemned by the United Nations Security Council.

What event has already finished?
