MacArthur and Wilson suggested
MacArthur and Wilson suggested that the biodiversity of an island will vary in direct proportion to a function of
the island’s size (i.e., larger islands can support a greater number of species) and in inverse proportion to a function
of its distance from the mainland (i.e., many remote islands will tend to support fewer species). Reduced
biodiversity in an island context is likely to require significant adaptation on the part of colonizing human
populations. Evans argues that this limitation makes islands ideal laboratories for the study of human adaptations to
the natural environment, whilst Renfrew and Wagstaff, in the introduction to their study of Melos, focus on this
limitation in biodiversity as a “significant characteristic of the island ecosystem.” For human communities,
however, this limitation may potentially be offset by other factors. The reduced biodiversity of an island ecosystem
applies only to terrestrial resources: the resources of the sea will be as rich as on any other coastal area, and may be
equally important to human communities. A small island such as Malta or Melos allows all communities direct
access to the sea, providing an important nutritional “safety net,” as well as an element of dietary diversity, which
may actually give island communities an advantage over their landlocked counterparts. Islands may also have
specific nonbiological resources (such as obsidian on Melos), which may be used in exchange with communities on
other islands and adjacent mainlands.
9. The primary purpose of the passage is to
A. evaluate two contrasting approaches to island biodiversity
B. discuss the relevance of certain data pertaining to island biodiversity
C. call into question a particular understanding of island biodiversity
D. consider various reasons for reduced biodiversity on islands
E. contrast large and small islands in terms of overall biodiversity
For the following question, consider each of the choices separately and select all that apply.
10. According to the author, factors of potential importance to human communities on islands include
A. the accessibility of the sea’s resources
B. a diet superior in some respects to the diet of landlocked communities
C. nonbiological resources that can be exploited
11. The author suggests that in considering the biodiversity of islands, Evans
A. focuses too exclusively on terrestrial resources
B. misunderstands the relationship between an island’s size and its terrestrial resources
C. misinterprets the work of MacArthur and Wilson
D. is wrong to assume that more remote islands support fewer species
E. downplays the ways that human communities adapt to island biodiversity
二
Although the percentage of
Although the percentage of first graders in Almaria who were excellent readers varied little between 1995 and 2010,
the percentage of first graders who had considerable difficulty reading their schoolbooks increased markedly during
that period. This evidence strongly indicates that the average reading ability of first graders decreased between
1995 and 2010.
16. Which of the following, if true, provides the strongest additional support for the argument?
A. The number of hours devoted to reading activities in first-grade classrooms in Almaria did not vary significantly,
on average, between 1995 and 2010.
B. The percentage of first graders in Almaria who had difficulty solving arithmetic problems did not increase as
much between 19950 and 2010 as did the percentage of first graders who had reading difficulties.
C. The number of children in Almaria who were enrolled as first graders decreased steadily between 1995 and
2010.
D. The average difficulty of the schoolbooks used in first-grade classrooms in Almaria decreased between 1995 and
2010.
E. The average number of schoolbooks used in first-grade classrooms in Almaria increased between 1995 and
2010.
Passage76. In 1919 Britain experienced
In 1919 Britain experienced its largest ever reduction in industrial working hours, to 48 per week. In Dowie’s
view the 48-hour week played a central role in Britain’s poor economic performance during the 1920s. Dowie
argued that the reduction, together with rapid wage growth, drove up prices. However, Greasly and Oxley found
that the First World War (1914-1918) constituted a more powerful negative macroeconomic shock to Britain’s
competitiveness. And Scott argues that Dowie’s thesis ignores considerable evidence that hourly productivity
improves when hours are reduced from a high level. Crucially, Dowie’s thesis does not acknowledge that
hours were reduced to around 48 hours a week for industrial workers in most industrialized nations at this time so
far—undermining any potential impact of reduced hours on industrial productivity relative to other nations.
17. Which of the following, if true, provides the strongest support for Scott’s argument?
A. Companies have generally found that part-time employees are less productive than full-time ones.
B. When the total number of hours worked at a company increases owing to the addition of more employees, the
usual result is improved productivity at the company.
C. When the total hours worked by all employees per week in two companies are equivalent, hourly productivity
tends to be equivalent as well.
D. Companies whose employees usually work a high number of hours tend to have greater total costs than do
similar companies whose employees work fewer hours.
E. Companies have found that total output per employee is not necessarily changed by reductions in the number of
hours worked per employee.
18. It can be inferred from the passage that in the view of Greasley and Oxley
A. a reduced workweek was ultimately beneficial to employees
B. the economic effects of the reduction in working hours in 1919 were brief
C. Britain became less economically competitive in the 1920s
D. reduced working hours were the primary cause of the economic changes observed by Dowie
E. the changes in economic performance in Britain in the 1920s were unforeseen
