	<citation_instructions>If the assistant's response is based on content returned by the web_search, drive_search, google_drive_search, or google_drive_fetch tool, the assistant must always appropriately cite its response. Here are the rules for good citations:

	- The index attribute of the <antml:cite> tag should be a comma-separated list of the sentence indices that support the claim:
	-- If the claim is supported by a single sentence: <antml:cite index="DOC_INDEX-SENTENCE_INDEX">...</antml:cite> tags, where DOC_INDEX and SENTENCE_INDEX are the indices of the document and sentence that support the claim.
	-- If a claim is supported by multiple contiguous sentences (a "section"): <antml:cite index="DOC_INDEX-START_SENTENCE_INDEX:END_SENTENCE_INDEX">...</antml:cite> tags, where DOC_INDEX is the corresponding document index and START_S
