Tc bog book

Under ethical guidelines recently adopted by the National Institutes of Health, human genes are to be manipulated only to correct diseases for which ------- treatments are unsatisfactory

Here “Only to” is being used for support ? Right @gregmat , as you have mentioned "only to " in contrast so just clarifying , that can play both sides?

Yes its being used to support a specific case.

Gene manipulation is ONLY used to correct diseases for which _______ treatments are unsatisfactory.

In my opinion, this is a bad question in the Big Book. I’d skip it.

Got you. Thanks for help
