A question can be an effective opening sentence for an essay unless?

Question

the writer overuses the device.

the reader is likely to have a negative answer.

the question has been asked before.

all of the above.

Answer 1

All of the above.

Overusing the device (using an opening sentence) can lessen interest of the readers.

If the reader will most likely have a negative answer, they will most likely not proceed reading because they already anticipate that they will disagree with the writer.

Having the question asked before makes it a cliche and there is less interest.

Answer 2

All of the above, and it is not recommended to open an essay with a question because if they say no your screwed. You should never open a historical essay or mainly any essay with a question.
