The data shows that above age 42, you have to be incredibly lucky to get pregnant with your own egg, says Norbert Glei-cher, founder of the Center for Human Reproduction in Chicago? (Klein 15).
The mistake in the above documentation is that:
O the name in the parentheses should be Glei-cher, not Klein since Glei-cher is the one who said the quotation
O quotes-within-a quote ("'aaa'") are needed to make it clear what Glei-cher said that Klein quoted and what Klein wrote that the student is quoting
O there should be no use of "you" even in a quotation
O there are no mistakes
