1. Archaeologists have found wheeled ceramic toys made by the Toltec, twelfth-century inhabitants of what is now Veracruz. Although there is no archaeological evidence that the Toltec used wheels for anything but toys, some anthropologists hypothesize that wheeled utility vehicles were used to carry materials needed for the monumental structures the Toltec produced.

Which of the following,if true,would most help the anthropologists explain the lack of evidence noted above?

A.The Toltec sometimes incorparated into their toys representations of utensils or other devices that served some practical purpose.

B. Any wheeled utility vehicles used by the Toltec could have been made entirely of wood, and unlike ceramic, wood decays rapidly in the humid climate of Veracruz.

C. Carvings in monument walls suggest that the Toltec's wheeled ceramic toys sometimes had ritual useds in addition to being used by both children and adults as decorations and playthings.

D. Wheeled utility vehicles were used during the twelfth century in many areas of the world, but during this time wheeled toys were not very common in areas outside Veracruz.

E. Some of the wheeled ceramic toys were found near the remains of monumental structures.

2. Adevertisement:

The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee Inc. So it only stands to reason that if you buy a can of Kreemo's  coffee, you're buying the best blended cofffee available today.

The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that

A. the equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers.

B. not all of Kreemo's  competitors use Colombian coffee beans in the blends of coffee they sell

C. Kreemo sells more coffee than does any other company.

D. Kreemo's coffee is the most expensive blended coffee available today

E. the best unblended coffee is better than the best blended coffee.

3. The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days——the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape's salespeople claim that Newtape adheres twice as long as the currently used tape does.

Which of the following statements, if true, would most seriously call into question the claim made by Newtape's salespeople?

A. Most surgical wounds take about ten days to heal.

B. Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.

C. The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten years.

D. Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned.

E. Newtape's  adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape's adhesion to such coated skin.
