Excavations on the now uninhabited isle of Kelton reveal a scene typical of towns decimated by volcanic ash.  Archaeologists have hypothesized that the destruction was due to volcanic activity known to have occurred in the vicinity of the island in 160 B. C.

Which of the following, if true, most strongly supports the archarologist’ hypothesis?

A. No coins minted after 160 B.C. were found in Kelton , but coincs minted before that year were found in abundance.

B. Pieces of gold and pearl jewelery that are often found in graves dating from years preceding and following 160 B.C. were also found in several graves on the island.

C.  Most modern histories of the region mention that  several major volcanoe erruptions occurred near the island in 160 B.C.

D.  Several small jugs carved in styles poplular in the region in the certury between 200 B.C. and 100 B.C. were found in Kelton.

E.  Drawings of the styles that was definitely used in the region after 160 B.C. were found in Kelton.

2.

With the proliferation of private companies that specialize in genetic research, it was feared that they would impose silence on the results of in-house research.  This constraint, in turn, would slow the progress of genetic engineering to alleviate patient suffering.

Which of the following, if true, most seriously weakens the prediction of scientific secrecy above?

A.  Genetic research funded by industry has reached some conclusions that are of major scientific importance.

B.  When the results of scientific research are kept secret, independent researcher are unable to build on those results.

C. To enhance the companies’ standing in the community, the genetic companies encourage employees to publish their results, especially results that are important.

D.  Since the research priorities of companies that specialize in genetic research are not the same as those of academic institutions, the financial support of research by such companies distorts the research agenda

E.  Companies that specialize in genetic research devote some of their research resources to problems that are of fundamental scientific importance and that are not expected to produce immediate practical applications.
