What (be) they ____(do)?They ________(play)checkers.

SAT语法题 关于时态的
29 【Of ancient origin】(A),the game of checkers 【was played】 (B) in Egypt 【during the time】(C) of the pharaohs and 【is mentioned】 (D) in the writings of Homer and Plato.No error(E)
这题是no error 然后D正确是因为checker是书本里提到的内容.我就想问如果这本书被毁了的话用什么时态...书已经不在了 那么里面的内容用过去式吗?
