ANALYTICAL WRITING ASSESSMENT

Analysis of an Issue

Directions: Using a word processor, compose a response to the

following statement and directive Do not use any spell-checking or grammar-checking functions

“No business should sacrifice the quality of its products or services for the sake of maximizing profits.”

Analysis of an Argument

Directions: Using a word processor, compose an essay for the following argument and

directive Do not use any spell-checking or grammar-checking functions

The following is excerpted from an editorial appearing in a local newspaper:

“In order to prevent a decline of Oak City’s property values and in rents that Oak City property owners can command, the residents of Oak City must speak out against the approval of a new four-year private college in their town After all, in the nearby town of Mapleton the average rent for apartments has decreased by ten percent since its new community college opened last year, while the average value

of Mapleton’s single-family homes has declined by an even greater percentage over the same time period.”

Discuss how well reasoned you find this argument In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion

QUANTITATIVE SECTION

Directions for Problem Solving Questions: (These directions will appear on your

screen before your first Problem Solving question.)

Solve this problem and indicate the best of the answer choices given

Numbers: All numbers used are real numbers.

Figures: A figure accompanying a Problem Solving question is intended to provide

infor-mation useful in solving the problem Figures are drawn as accurately as possible EXCEPT

when it is stated in a specific problem that its figure is not drawn to scale Straight lines

may sometimes appear jagged All figures lie on a plane unless otherwise indicated

Directions for Data Sufficiency Questions: (These directions will appear on your

screen before your first Data Sufficiency question.)

This Data Sufficiency problem consists of a question and two statements, labeled (1) and

(2), in which certain data are given You have to decide whether the data given in the

statements are sufficient for answering the question Using the data given in the

statements plus your knowledge of mathematics and everyday facts (such as the

number of days in July or the meaning of counterclockwise), you must indicate whether:

(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to

answer the question asked;

(B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to

answer the question asked;

(C) BOTH statements (1) and (2) TOGETHER are sufficient to answer the

question asked, but NEITHER statement ALONE is sufficient;

(D) EACH statement ALONE is sufficient to answer the question asked;

(E) Statements (1) and (2) TOGETHER are NOT sufficient to answer the question

asked, and additional data specific to the problem are needed

Numbers: All numbers used are real numbers.

Figures: A figure accompanying a Data Sufficiency problem will conform to the

information given in the question, but will not necessarily conform to the additional

information in statements (1) and (2)

Lines shown as straight can be assumed to be straight and lines that appear jagged can

also be assumed to be straight

You may assume that positions of points, angles, regions, etc., exist in the order shown

and that angle measures are greater than zero

All figures lie in a plane unless otherwise indicated

Note: In Data Sufficiency problems that ask you for the value of a quantity, the data

given in the statements are sufficient only when it is possible to determine exactly one

numerical value for the quantity
