Which sentence contains an error in the reported wh-question contrast between statement order and inversion?
The botanist asked why the seedlings were drooping near the window.
The guard asked where did the portrait disappear during the closure.✓Bonne réponse
The editor asked how the quotation had entered the final proof.
The coach asked when the replacement bus would reach the stadium.
Explication
The gallery sentence is erroneous because did the portrait disappear preserves direct-question inversion after where. A reported wh-clause instead places the subject before the verb and omits do-support.
