PrepTest 103

Incorrect. This answer describes a Circular Reasoning flaw. The conclusion here, though, takes information about physiological maturity and an obligation of society to give people privileges and brings it together, so it's not simply a restatement of the premises.

Incorrect. This answer can be tempting because the premises are about "most seventeen-year-olds." However, the conclusion is also about "these citizens"—the majority of 17-year-olds who are physiologically mature—and so it doesn't generalize.

Incorrect.

Incorrect. This answer is also a very tempting trap answer! The argument does rely on science to establish something about the physiological maturation process. However, science isn't an inappropriate authority to speak to when people generally complete that process. The problem with the argument is that this claim isn't related to the conclusion, not that the authority raising that claim is the wrong one to do so.

Incorrect. The conclusion is about granting privileges to 17-year-olds who have finished the physiological maturation process. That doesn't preclude granting those privileges to 16-year-olds who have undergone it, so this answer is out of scope.
