Because of strong overall stylistic similarities, prehistoric cave paintings in El Castillo, Spain and others in Altamira, Spain, were thought to date from the same period. Recent pigment analyses, however, established the Altamira paintings as by far the older and as about the same age as a third group of paintings done in a different overall style. Nevertheless, this case does not prove that stylistic similarities cannot be a reliable indicator of closeness in age, since ____________.
16. Which of the following most logically completes the passage?
A. experts who knew the results of the pigment analyses reexamined these paintings and found no previously unnoticed stylistic similarities between the Altamira paintings and the paintings in the third group
B. there are certain stylistic features that the Altamira paintings share with all known paintings of their period and do not share with the El Castillo paintings
C. before dating by pigment analysis was widely practiced, stylistic similarities were the only means of determining whether two prehistoric cave paintings dated from the same period
D. determining the age of a prehistoric cave painting simply by reference to the age of the pigments used in that painting substitutes technology for artistic judgment
E. there are experts who maintain that the results of the recent pigment analyses leave the striking stylistic similarities between the El Castillo paintings and the Altamira paintings unexplained
A hoard of coins recently unearthed at an ancient Carthagian site bear an image of a face in profile with what appears to be a large mole on the cheek. Pointing out that an artist would be unlikely to include such a specific detail in a generalized portrayal of a face, some archaeologists have concluded that these coins portray an actual individual rather than an idealized type. However, this conclusion is unwarranted, since ______.
14. Which of the following most logically completes the argument?
A. archaeologists cannot determine the actual identity of the individual portrayed just from the likeness that appears on the coins
B. it cannot be established with certainty that Carthagian artists were on the whole less skillful at portraying human face than artists of other cultures
C. none of the other designs of Carthagian coins that have been discovered features a face with a mole on it
D. in ancient times it was quite common for the money circulated in a city or country to include coins that originated in other jurisdictions.
E. the relatively soft metal used for Carthagian coin molds sometimes resulted in the production of series of coins with unintended bumps
