The number of calories in a gram of refined cane sugar is the same as in an equal amount of fructose,the natural sugar found in fruits and vegetables. Therefore, a piece of candy made with a given amount of refined cane sugar is no higher in calories than a piece of fruit that contains an equal amount of fructose The reasoning in the argument is flawed because the argument (A) fails to consider the possibility that fruit might contain noncaloric nutrients that candy does not contain 4.

The cumbersome spears that were the principal weapons used by certain tribes in the early Bronze Age precluded widespread casualties during intertribal conflicts. But the comparatively high number of warrior tombs found in recent excavations of the same tribes' late Bronze Age settlements indicates that in the late Bronze Age, wars between these tribes were frequent, and the casualty rate was high. Hence some archaeologists claim that by the late Bronze Age, these tribes had developed new methods of warfare designed to inflict many casualties. Which one of the following, if true most supports the archaeologists' claim? (A) A royal tomb dating to the early Bronze Age contained pottery depicting battle scenes in which warriors use spears. 8. Based on data collected from policyholders, life insurance companies have developed tables that list standard weight ranges for various heights.

Therefore, if people whose weight falls outside their given range modified their weight to fall within that range, their overall life expectancies would improve. Which one of the following is an assumption on which the argument relies? (A) Some people would be unwilling to modify their weights solely to increase the general population's overall life expectancies. |
