The loss of the account was a great shock to him, as he was not accustom to failure.

Where is the mistake?
A. loss of the account
B. great shock to
C. not accustom
D. to failure

“Accustom” is actually a verb. Here it appears in the passive voice, so it should be “was accustomed” rather than “was accustom”. The correct answer is C.


「Accustom(慣らす)」は、実は動詞です。ここでは受け身になっているので「was accustom」ではなくて「was accustomed」が正しいです。正解はCです。
