Anthropologist: The culture responsible for the inscriptions at the site must have used fire to fashion iron implements. Of the Xa, Ye, and Zi, the three cultures known to have inhabited the area surrounding this site, the Xa could obtain iron but could not use fire to fashion implements and the Ye had no access to iron. Therefore the Zi is the only culture known to be from the surrounding area that could have made these inscriptions.
The reasoning in which one of the following arguments is most closely parallels the reasoning used in the argument above?
a.) Whoever commited the burglary wore size nine shoes. Of the three suspsects in custody, Jensen Kapp and Lomax, neither Jensen nor Lomax could have worn size nine shoes. Of the three suspects in custody, therefore, nobody but Kapp could be the burglar.
b.) The person who designed the Ultra180 must have been a very patient person. Of three well-known designers, Morris, Nieves, and Ott, who worked for Ultra's manufacturer when the ultra 180 was designed, Morris and Ott were both impatient people. Therefore, Nieves is the only person who could have designed the Ultra 180.
Which one is right and WHY IS THE WRONG ANSWER WRONG? I seriously couldn't distinguish between those two.
