There are many structural and thematic similarities between Piers Plowman by Langland (1330-1400) and House of Fame by Chaucer (1342-1400), two Middle English poems relating dream visions. Some critics have argued that because a number of the shared elements are uncommon in Middle English poetry, and because Langland’s poem probably predates Chaucer’s by a few years, Chaucer was most likely influenced by Piers Plowman when writing House of Fame.
5. Which of the following, if true, most seriously weakens the critics’ argument?
A. Piers Plowman is one of Langland’s major works, whereas House of Fame is a minor work of Chaucer’s.
B. House of Fame survives in only three manuscript copies, substantially fewer than the number of manuscript copies that exist of Piers Plowman.
C. Because Piers Plowman became a well-known work in its day, it is likely that the similarities between it and House of Fame were detected by many of the people who read House of Fame soon after Chaucer wrote it.
D. Many of the themes and structures of Piers Plowman are also found in Latin, Italian, French works with which Chaucer could well have been familiar.
E. There is no evidence that Chaucer and Langland ever met or that they corresponded with each other about literary topics.
答案：D

Sportfishers introduced the Zander, a type of perch, to Britain’s rivers and canals in the 1970s. Because zander eat large numbers of smaller fish, they have had a devastating effect on native fish populations. To protect the native fish, a government program removed a significant proportion of the zander from Britain’s waterways last year. Surprisingly, this year the loss of native fish to zander has been greater than before.
4. Which of the following, if true, would most help to explain the greater effect of zander on the native fish population?
A. The climate in Britain is very similar to the climate in regions to which zander are native.
B. Most of the zander removed were fully grown, and fully grown zander eat large numbers of smaller zander.
C. Every year a large number of zander are caught by sportfisher in Britain’s waterway.
D. Previous government program designed to remove nonnative species from Britain’s waterways have failed.
E. Zander are just one of several nonnative fish that prey on the other fish found in Britain’s waterway.
答案：B

New methods developed in genetic research have led taxonomists to revise their views on the evolutionary relationships between many species. Traditionally the relatedness of species has been ascertained by a close comparison of their anatomy. The new methods infer the closeness of any two species’ relationship to each other directly from similarities between the species’ genetic codes.
3. Which of the following conclusions is best supported by the information?
A. The apparent degree of relatedness of some species, as determined by anatomical criteria, is not borne out by their degree of genetic similarity.
B. When they know the differences between two species’ genetic codes, taxonomists can infer what the observable anatomical differences between those species must be.
C. The degree to which individuals of the same species are anatomically similar is determined more by their genetic codes than by such environmental factors as food supply.
D. The traditional anatomical methods by which taxonomists investigated the relatedness of species are incapable of any further refinement.
E. Without the use of genetic methods, taxonomists would never be able to obtain any accurate information about species’ degrees of relatedness to one another.

Stylistic evidence and laboratory evidence strongly support the claim that the magnificent painting Garden of Eden is a work of the Flemish master van Eyck. Nevertheless, the painting must have been the work of someone else, as anyone with a little historical and zoological knowledge can tell merely by looking at the painting. The animals in the painting are all vivid representations of actual animals, including armadillos. Yet armadillos are native only to Americas, and van Eyck died decades before Europeans reached the Americas.
