Decipher the Human Genetic Code?

Which one of the following most accurately expresses the conclusion of the ethicist's argument?

Ethicist: Robert Gillette as argued that because a thorough knowledge of genetics would enable us to cure the over 3,000 inherited disorders that affect humanity, deciphering the human genetic code will certainly benefit humanity despite its enormous cost. Gillette's argument is not persuasive, however, because he fails to consider that such knowledge might ultimately harm human beings more than it would benefit them.

Answer: Gillette's argument is unconvincing because it ignores certain possible consequences of genetic research.
