我想有有關reported speech既野~

唔可以咁寫嫁....

Reported Speech 既句子結構一定係要 Subject + Verb + Object....同時個tense 一定係present tense 轉為 past tense OR past tense 轉為 past perfect tense....

係呢一題度， did + find = VERB, 所以唔可以係 where did + he + usually find +....應該係: he saked where he usually found potential athletes. After where, Subject should come first than Verb.

Hope can make u understand more about reported speech....

Your answer is wrong.
It should be
He asked where he (she) usually found potential athlets.
