`check_claim`Check one dated sentence against the record before stating it. Leaders, Billboard No. 1 singles and Nobel Prizes get a structured check that can return 'supported' or 'contradicted' with the source. Other claims are matched against the dated entries and the answer says where the record dates sentences holding the claim's key words (matched_same_year, matched_other_years, ...), with the entries as evidence.
