发两道逻辑难题

1. The Ptolemies, a Greek dynasty that ruled Egypt, brought to Alexandria statues made centuries earlier for the native Egyptian monarchs at the former capital, Heliopolis. Two colossal statues of male rulers found in Alexandria’s harbor among Ptolemaic ruins are in a style very similar to that of the ancient Heliopolis statues, but they have facial features that are characteristically Greek. Therefore, the two colossal statues were probably made during Ptolemaic times, specifically under Ptolemy II, since ...

. ΧWhich of the following most logically completes the argument?
A. their colossal size is matched by many of the statues of male rulers found in Heliopolis but by very few other statues found in Alexandria
B. most of the statues taken from Heliopolis were brought to Alexandria under Ptolemy II
C. they were found among the ruins of a majestic lighthouse built by Ptolemy II as part of his extensive reconstruction of Alexandria’s harbor
D. a colossal statue of a female figure found next to the two statues also has characteristically Greek facial features
.--E. during Ptolemaic times, many Greek artists and scholars lived and worked in Alexandria


2. Ten years ago off Garnea Island, large numbers of sea turtles were being trapped and drowned in commercial shrimping nets, and the sea-turtle population was rapidly declining. A law was passed requiring shrimping nets to have special flaps that enable trapped turtles to escape. Initially, compliance was strictly monitored, and sea-turtle deaths fell dramatically. In recent years, however, boats are monitored less frequently, and sea-turtle deaths have significantly increased. Clearly, therefore, compliance has decreased.

Which of the following, if true, most strengthens the argument?
A. The local shrimping industry, which ten years ago employed fewer than 5,000 people, now employs over 15,000 people and is one of the largest industries in the region.
-In the months in which shrimping is banned to enable shrimp to grow, sea-turtle deaths have changed little in the last six years.
-Officials responsible for overseeing compliance with the law contend that over 70 percent of shrimpers have the required flaps in their nets.
-Because of the number of small boats involved in shrimping, thorough monitoring is both difficult and expensive.
-Marine biologists credit the law with almost tripling the size of the local sea-turtle population within six years of passage.
