General Information:
The College Board™ developed Accuplacer™ Computerized Placement Tests (CPTs), with the assistance of college professors, to provide information concerning the entry level skills of incoming college students in the areas of reading, writing and mathematics. Appropriate course placement is critical for success in college and according to the Department of Education Rule 6A-10.315: “. . . first-time-college students who intend to enter degree programs will be tested prior to initial registration and shall enroll in college preparatory courses if their test scores are below college level.” SAT or ACT scores that are college level and no more than two years old may be substituted for the CPT. Placement test scores will be reviewed with an advisor upon registration to assist the student in selecting the appropriate courses and developing an academic plan.
The CPT is a computerized test. It is very user friendly. After typing in personal information, the student need utilize only the enter key and space bar. All test questions are multiple choice. Only one question is shown at a time. The test is adaptive. This means that the first question asked is of medium difficulty. If answered correctly, then the computer automatically gives a slightly more difficult question next. If answered incorrectly an easier question is given. Obviously, the more difficult the questions, the more they are worth in determining the end results. The test is not timed so there is no pressure to answer quickly. If the answer is not known, try to eliminate one or more of the choices and then pick one of the remaining answers. Scores will be given when testing is complete. Scores are good for two years.

Read the pair of
passages below and then choose the best answer to the associated questions.
Answer the questions based on what is stated or implied in the passages.
14. French physicist Charles Fabry found ozone gas in the atmosphere in 1913. At room temperature, ozone is a colorless gas; it condenses to a dark blue liquid at -170º F. At temperatures above the boiling point of water, 212º F, it decomposes.
Ozone is all around us. After a thunderstorm, or around electrical equipment, ozone is often detected as a sharp odor. Ozone is used as a strong oxidizing agent, a bleaching agent, and a sterilizing agent in drinking water. This gas is also highly reactive. For example, rubber insulation around a car’s spark plug wires will need to be replaced eventually, due to the small amounts of ozone produced when electricity flows from the engine to the plug.
These passages imply that:
a. Ozone is the result of pollution.
b. High ozone levels in the atmosphere will cause large numbers of people to buy new car batteries.
c. Ozone has no practical uses.
d. Ozone is a natural part of the Earth’s atmosphere.
15. Before video cameras were widely used, home and business owners had to rely only on written reports and photos as a way to document their valuables for insurance purposes. This form of documentation was difficult for some insurance policy holders. They found it was easy to lose lists, forget to add new items they purchased, or delete items they no longer had. As a result, these insurance inventories were often inaccurate.
While video taping is not an option for every home or business owner, this kind of insurance documentation is helpful for some.
How are these passages related?
a. They repeat the same idea.
b. They contradict one another.
c. They compare two forms of written documentation.

2. c: Use a colon between independent clauses if the second summarizes or explains the first.
3. c: The misplaced modifier in the original confuses the meaning of the sentence.

17. c: Avoid using ambiguous references to “you.” Construct sentences for clarity. People don’t have traffic jams; cars do.
18. d: The new sentence upgrades the dependent clause “as anyone . . . knows” to an independent clause. The new sentence includes “knows that tornadoes are” – subordinating the main idea, “tornadoes are winds. . .”
19. b: The dependent clause has been reduced to an introductory verbal phrase modifying the subject.
20. b: Avoid unnecessary words which can jumble the flow of the sentence.
21. a: When an independent clause is followed by a dependent clause, a comma is usually unnecessary.
22. b: Two independent clauses joined by a coordinating conjunction (and, but, so, or, for, nor, yet) need a comma after the first clause.
23. d: When a dependent clause introduces the sentence, a comma is needed after the clause.
24. b: This version makes more sense because earning the money is in fact the cause of his not needing to sell his pen, and the sentence is grammatically correct.

10. c: Hint: solve by substitution
Use x – 3y = 12, solve for x; x = 3y +12
and substitute into first equation
2(3y +12) + y = 3, solve for y
6y + 24 + y = 3
7y + 24 = 3
7y = -21
y = -3, substitute y value into other equation.
x – 3(-3) = 12
x + 9 = 12
x = 3
