Dr. Summer: But an expected level of heart disease is 5 percent, or in other words, 1 out of every 20 people. So at any given time if a person knows approximately 50

people, 1 or more will very likely suffer from heart disease.1st question: Dr. Summer’s argument is structured to lead to which of the following conclusion?

A) The fact that 90 percent of the people know someone who suffers from heart disease is not an indication that heart disease is abnormally high.
B) The current level of heart disease is not moderate.
C) If at least 5 percent of the population suffered from heart disease, the result of questioning a representative group of people cannot be the percentage the interviewer cites.
D) It is unlikely that the people whose statements the interviewer cites are giving accurate reports.
E) If a person with heart disease is given as a certain percent, the actual percentage of those with heart disease is even higher.

Musicologists concerned with the “London Pianoforte school,” the group of composers, pedagogues, pianists, publishers, and builders who contributed to the development of the piano in London at the turn of the nineteenth century, have long encountered a formidable obstacle in the general unavailability of music of this “school” in modern scholarly editions. Indeed, much of this repertory has more or less vanished from our historical consciousness. Granted, the sonatas and Gradus ad Parnassum of Muzio Clementi and the nocturnes of John Field have remained familiar enough (though more often than not in editions lacking scholarly rigor), but the work of other leading representatives, like Johann Baptist Cramer and Jan Ladislav Dussek, has eluded serious attempts at revival.
Nicholas Temperley’s ambitious new anthology decisively overcomes this deficiency. What underscores the intrinsic value of Temperley’s editions is that the anthology reproduces nearly all of the original music in facsimile. Making available this cross section of English musical life—some 800 works by 49 composers—should encourage new critical perspectives about how piano music evolved in England, an issue of considerable relevance to our understanding of how piano music developed on the European continent, and of how, finally, the instrument was transformed from the fortepiano to what we know today as the piano.

To be sure, the London Pianoforte school itself calls for review. “School” may well be too strong a word for what was arguably a group unified not so much by stylistic principles or aesthetic creed as by the geographical circumstance that they worked at various times in London and produced pianos and piano music for English pianos and English markets. Indeed, Temperley concedes that their “variety may be so great as to cast doubt on the notion of a ‘school.’”

The notion of a school was first propounded by Alexander Ringer, who argued that laws of artistic survival forced the young, progressive Beethoven to turn outside Austria for creative models, and that he found inspiration in a group of pianists connected with Clementi in London. Ringer’s proposed London Pianoforte school did suggest a circumscribed and fairly unified group—for want of a better term, a school—of musicians whose influence was felt primarily in the decades just before and after 1800. After all, Beethoven did respond to the advances of the Broadwood piano—its reinforced frame, extended compass, triple stringing, and pedals, for example—and it is reasonable to suppose that London pianists who composed music for such an instrument during the critical phase of its development exercised no small degree of influence on Continental musicians. Nevertheless, perhaps the most sensible approach to this issue is to define the school by the period (c. 1766-1873) during which it flourished, as Temperley has done in the anthology.

1) Which one of the following most accurately states the author’s main point?
(A) Temperley has recently called into question the designation of a group of composers, pedagogues, pianists, publishers, and builders as the London Pianoforte school.
(B) Temperley’s anthology of the music of the London Pianoforte school contributes significantly to an understanding of an influential period in the history of music.
(C) The music of the London Pianoforte school has been revived by the publication of Temperley’s new anthology.
(D) Primary sources for musical manuscripts provide the most reliable basis for musicological research.
(E) The development of the modern piano in England influenced composers and other musicians throughout Europe.

2) It can be inferred that which one of the following is true of the piano music of the London Pianoforte school?
(A) The nocturnes of John Field typify the London Pianoforte school style.
(B) The Gradus ad Parnassum of Muzio Clementi is the best-known work of these composers.
(C) No original scores for this music are extant.
(D) Prior to Temperley’s edition, no attempts to issue new editions of this music had been made.
(E) In modern times much of the music of this school has been little known even to musicians.

3) The author mentions the sonatas of Muzio Clementi and the nocturnes of John Field as examples of which one of the following?
(A) works by composers of the London Pianoforte school that have been preserved in rigorous scholarly editions
(B) works that are no longer remembered by most people
(C) works acclaimed by the leaders of the London Pianoforte school
(D) works by composers of the London Pianoforte school that are relatively well known
(E) works by composers of the London Pianoforte school that have been revived by Temperley in his anthology

4) Which one of the following, if true, would most clearly undermine a portion of Ringer’s argument as the argument is described in the passage?
(A) Musicians in Austria composed innovative music for the Broadwood piano as soon as the instrument became available.
(B) Clementi and his followers produced most of their compositions between 1790 and 1810.
(C) The influence of Continental musicians is apparent in some of the works of Beethoven.
(D) The pianist-composers of the London Pianoforte school shared many of the same stylistic principles.
(E) Most composers of the London Pianoforte school were born on the Continent and were drawn to London by the work of Clementi and his followers.

5) It can be inferred that the author uses the word “advances” (line 49) to refer to
(A) enticements offered musicians by instrument manufacturers
(B) improvements in the structure of a particular instrument
(C) innovations in the forms of music produced for a particular instrument
(D) stylistic elaborations made possible by changes in a particular instrument
(E) changes in musicians’ opinions about a particular instrument

6) It can be inferred from the passage as a whole that the author’s purpose in the third paragraph is primarily to
(A) cast doubt on the usefulness of Temperley’s study of the London Pianoforte school
(B) introduce a discussion of the coherency of the London Pianoforte school
(C) summarize Ringer’s argument about the London Pianoforte school
(D) emphasize the complex nature of the musicological elements shared by members of the London Pianoforte school
(E) identify the unique contributions made to music by the London Pianoforte school

7) The author of the passage is primarily concerned with
(A) explaining the influence of the development of the pianoforte on the music of Beethoven
(B) describing Temperley’s view of the contrast between the development of piano music in England and the development of piano music elsewhere in Europe
(C) presenting Temperley’s evaluation of the impact of changes in piano construction on styles and forms of music composed in the era of the London Pianoforte school
(D) considering an alternative theory to that proposed by Ringer concerning the London Pianoforte school
(E) discussing the contribution of Temperley’s anthology to what is known of the history of the London Pianoforte school

It can be inferred that Temperley’s anthology treats the London Pianoforte school as
(A) a group of pianist-composers who shared certain stylistic principles and artistic creeds
(B) a group of people who contributed to the development of piano music between 1766 and 1873
(C) a group of composers who influenced the music of Beethoven in the decades just before and just after 1800
(D) a series of compositions for the pianoforte published in the decades just before and just after 1800
(E) a series of compositions that had a significant influence on the music of the Continent in the eighteenth and nineteenth centuries

Woodsmoke contains dangerous toxins that cause changes in human cells. Because woodsmoke presents such a high health risk, legislation is needed to regu- late the use of open-air fires and wood-burning stoves. Which of the following, if true, provides the most support for the argument above?

(A) The amount of dangerous toxins contained in woodsmoke is much less than the amount
contained in an equal volume of automobile exhaust.
(B) Within the jurisdiction covered by the proposed legislation, most heating and cooking is done
with oil or natural gas.
(C) Smoke produced by coal-burning stoves is signif- icantly more toxic than smoke from wood-
burning stoves.
(D) No significant beneficial effect on air quality would result if open-air fires were banned within the jurisdiction covered by the proposed legislation.
(E) In valleys where wood is used as the primary heating fuel, the concentration of smoke results
in poor air quali

Although aspirin has been proven to eliminate moderate fever associated with some illnesses, many doctors no longer routinely recommend its use for this purpose. A moderate fever stimulates the activity of the body’s disease-fighting white blood cells and also inhibits the growth of many strains of disease-causing bacteria.

If the statements above are true, which of the following conclusions is most strongly supported by them?

(A) Aspirin, an effective painkiller, alleviates the pain ?and discomfort of many illnesses.

(B) Aspirin can prolong a patient’s illness by eliminat?ing moderate fever helpful in fighting some

?diseases.

(C) Aspirin inhibits the growth of white blood cells, ?which are necessary for fighting some illnesses.

(D) The more white blood cells a patient’s body ?produces, the less severe the patient’s illness ?will be.

(E) The focus of modern medicine is on inhibiting the ?growth of disease-causing bacteria within the ?body.

The recent upheaval in the office-equipment retail business, in which many small firms have gone out of business, has been attributed to the advent of office equipment “superstores” whose high sales volume keeps their prices low. This analysis is flawed, however, since even today the superstores control a very small share of the retail market.

Which of the following, if true, would most weaken the argument that the analysis is flawed?

(A) Most of the larger customers for office equipment purchase under contract directly from manufacturers and thus do not participate in the retail market.

(B) The superstores’ heavy advertising of their low prices has forced prices down throughout the   retail market for office supplies.

(C) Some of the superstores that only recently opened have themselves gone out of business.

(D) Most of the office equipment superstores are owned by large retailing chains that also own     stores selling other types of goods.

(E) The growing importance of computers in most offices has changed the kind of office equipment retailers must stock.

Hardin argued that grazing land held in common (that is, open to any user) would always be used less carefully than private grazing land. Each rancher would be tempted to overuse common land because the benefits would accrue to the individual, while the costs of reduced land quality that results from overuse would be spread among all users. But a study comparing 217 million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition.

Which of the following, if true and known by the ranchers, would best help explain the results of the study?

A) With private grazing land, both the costs and the benefits of overuse fall to the individual user.

B) An individual who overuses common grazing land might be able to achieve higher returns than other users can, with the result that he or she would obtain a competitive advantage.

C) The cost in reduced land quality that is attributable to any individual user is less easily measured with common land than it is with private land.

D) If one user of common land overuses it even slightly, the other users are likely to do so even more, with the consequence that the costs to each user outweigh the benefits.

E) There are more acres of grazing held privately than there are held in common.

It takes 4 weeks for 5 professional window washers working regular full-time hours to properly clean every window of the Empire State Building. The building’s owner demands that all the windows must always be clean. Yet even if the 5 washers work consistently throughout their regular work week, they will not be able to finish cleaning all the windows before some windows will again need cleaning.

It can be correctly inferred on the basis of the statements above that which of the following must be true?

A) If an Empire State Building window is to be kept clean, it must be cleaned by a professional window cleaner.

B) The owner’s demand for proper cleaning of all the windows will never be fulfilled.

C) If a team of 5 window washers cleans all the Empire State Building’s windows in less than 4 weeks, some of the windows will not be properly cleaned.

D) In order to ensure that all of the Empire State Building’s windows are clean, the owner must have his window washers work overtime.

E) Some Empire State Building windows must be cleaned more frequently than once every four weeks if they are to be kept clean.

The candy manufacturer’s claim that employee “theft” costs the company thousands of dollars every year in potential sales is greatly overstated. Most of the candy eaten on the job and not paid for is eaten one piece at a time, by workers who would not be willing to buy an entire box of it anyway.

Which of the following, if true, most weakens the argument above?

A) The workers eat only defective candies that could not be sold.

B) Candy eaten by employees represents lost potential sales to non-employees.

C) A few workers account for most of the candy that is eaten but not paid for

D) Most of the candies eaten by employees are consumed during the holiday season, when production outputs are at their highest.

E) The amount of candy eaten by employees is only a small fraction of the candy sold by the company

In response to mounting pubic concern, an airplane manufacturer implemented a program
with the well-publicized goal of reducing by half the total yearly amount of hazardous
waste generated by its passenger-jet division. When the program began in 1994, the
division’s hazardous waste output was 90 pounds per production worker; last year it was
40 pounds per production worker. Clearly, therefore, charges that the manufacturer’s
program has not met its goal are false.
