1. Yes

2. Right.

3. It has not been mentioned in any official guideline that the correct answer must retain the meaning of the original sentence. If there is only one grammatically correct choice, it must be selected even when it deviates in meaning from the original. However if there are two grammatically correct sentences, select the one that agrees with the intended meaning of the original sentence.

The phrase " X is accounted for" is used to mean that it is known where X is or what happened to X. e.g., After the earthquake, 10 of the inhabitants could not be accounted for. This usage is inappropriate here.


The phrase "held accountable for" means "held responsible for". This meaning is correct in this context.
