"a" or "the"

Hi everyone,
I’ve found this on Delta’s book for TOEFL and I think it’s not correct, Would you please tell me if I am right or wrong about this?

Which fact should be included in a biography of Dorothy Reed Mendenhall?
And I think the correct sentence is:
Which fact should be included in the biography of Dorothy Reed Mendenhall?

Kind regards


Not really. ‘A’ suggests ‘one’. After all there can be more than one biography.


Thanks Alan for the answer.


Allan you mean using "the " is completely incorrect?No way?

Hi Mzahed,

albeit I´m not Alan, I dare mention that the article “the” not necessarily was wrong.

What Alan refered to was that if there isn´t linked to a very special biography of that special person and since there might be several ones the article “a” was right…because it´s indefinite.

Another kettle of fish is, when there are several biographies and the writer refered to a very special one the definite article “the” must be used.

Hope this helped


Thanks Foah
