CLEP Answers

College Mathematics

1. The correct answer is (C).

Try using a numerical value; let n = 3

n + 1 = 4
(n + 1)2 = 16
n2 = 9
n2 + 1 = 10

Choice (C) is the only one that results in an odd number.


1. The correct answer is (D). William Butler Yeats was the Irish poet and playwright who co-founded the Irish National Theatre Society, which became Dublin’s famous Abbey Theatre. He is known for the poems ”Leda and the Swan,” ”The Second Coming,” ”The Lake Isle of Innisfree,” and many other works, and was awarded the Nobel Prize in literature in 1923.

2. The correct answer is (C). Kurosawa directed Roshomon in 1950. An examination of the nature of truth, the work awakened Western interest in Japanese cinema.

English Composition

Identifying Sentence Errors

1. The correct answer is (D). The verb in a sentence, clause, or phrase must agree with its’ subject in number. In this sentence, the subject of the sentence is total, which is singular. This means that the verb must be singular as well. The verb in this sentence must be changed to ”is.”

Improving Sentences

1. The correct answer is (B). The other choices are wordy or create illogical sentences. “Was because” is an error because it is a mixed construction that attempts to use an adverb clause (”because the president … money”) as a predicate nominative, which renames the subject.

Revising Work in Progress

1. The correct answer is (B). Choice (B) combines all the information together in the correct grammatical format. Choice (A) is incorrect because it adds extra information that was not present in the original two sentences (the father speaking to the mother’s family). Choice (C) is false because it deletes the information about the father speaking of his roots. Choice (D) is wrong since these two sentences are intended by the writer to juxtapose two separate lifestyles. The use of “and” is incorrect stylistically because it indicates the joining of equal ideas. Choice (E) is wrong because it is too wordy.

Natural Sciences

1. The correct answer is (C). DDT and PCB are lipid-soluble compounds and are therefore found in lipid tissues. As their half-lives are quite long, DDT = 10 years, there is a magnification of these compounds in food chains; e.g., DDT has been found in high concentrations in the fatty tissues of Antarctic penguins.

2. The correct answer is (B). This question can be answered when one pictures the actions of molecules on a molecular level. They are continually vibrating and colliding. The addition of very fine particles will cause collisions between these particles and the molecules of the liquid, resulting in the movement of the particles. This behavior is called Brownian motion.

Social Sciences and History

1. The correct answer is (C). Maryland refused to ratify the Articles of Confederation until all states agreed to cede to the Union their claims to all lands in the western territories.

2. The correct answer is (C). Lines of latitude and longitude are parallel on a Mercator projection map; thus, mathematical locations are accurate, but dimensions of areas are distorted.
