The revised checklist was especially ____ to new employees during training.
看答案
beneficial
was especially ____ to new employees 需要形容詞作主詞補語，beneficial 符合。benefit 作單數可數名詞時需要冠詞，作動詞也不能直接接在 was especially 後；beneficially 是副詞，不能單獨作此補語；benefits 是複數名詞或第三人稱單數動詞形式，均不符合完整句的結構。
同義改寫

此處 beneficial 與 helpful 都表示練習課程對新進接待人員有幫助，未加入特定成效。

mutually beneficial 表示雙方都受益，改為以兩個部門作主詞的 benefited 句型，保留互惠的意思。
