the reasoning above exhibits a flaw similar to one in which of the following?
a. any member of the solar system must be either a planet or a moon, so if an asteroid is neither a planet nor a moon, it must not be a member of the solar system.
b. anyone who rides a city bus must buy a bus pass, and since demetrios has a bus pass, he must be riding on a city bus.
c. a driver who turns right must signal, so any driver who did not signal must not have turned right.
d. anyone who legally crosses a national boundary must have a passport; thus anyone who does not have a passport cannot legally cross a national boundary.
e. any wage earner residing in the state must pay state taxes, so since blodwen pays state taxes, she must be resident in the state.
