答案

Is this museum (where) they stayed yesterday?（where引导表语从句）
Is this the museum ( which/that/不填) they visited yesterday?（which/that引导定语从句,修饰先行词the museum,在从句中作宾语时可省略）
Is this museum (the one) you visited yesterday?（the one作定语从句的先行词）
Was it the museum (where) you saw many treasures?（where引导定语从句,在从句中作状语）
Was it in the museum (where) you dropped in that you saw many treasures?（where引导定语从句,在从句中作状语；drop in 后接宾语时后须跟介词on或at）
It was in the museum (that) you saw many treasures.（本句为强调句型）
