1. Express the solution to the following problem in decimal form:

A. 0.042
B. 84%
C. 0.84
D. 0.42

Correct answer: C

Rationale: The correct answer is C: 0.84. To convert a percentage to a decimal, you divide the percentage value by 100. In this case, 84% divided by 100 equals 0.84. Choice A, 0.042, is not the correct conversion of 84%. Choice B, 84%, is already in percentage form and needs to be converted to a decimal. Choice D, 0.42, is not the correct conversion of 84% either. Therefore, the correct decimal form of 84% is 0.84.

2. Which of the following is a compound sentence?

A. Plague, generally not a major public health concern, actually continues to spread among rodent populations today, and it even occasionally makes its way into a human host.
B. Modern archaeology, which seeks answers to humanity’s questions about its past, is significantly helped by new technologies.
C. In the fight against obesity, countries around the world are imposing taxes on sodas and other sugary drinks in an effort to curb unhealthy habits.
D. Because the assassination of President John F. Kennedy continues to haunt and fascinate Americans, new movies, books, and television series about it are released every year.

Correct answer: A

Rationale: A compound sentence consists of two or more independent clauses that are joined by coordinating conjunctions such as 'and,' 'but,' or 'or.' In choice A, the sentence contains two independent clauses separated by the coordinating conjunction 'and': 'Plague, generally not a major public health concern, actually continues to spread among rodent populations today' and 'it even occasionally makes its way into a human host.' Choice B is a complex sentence as it contains a dependent clause 'which seeks answers to humanity’s questions about its past' and an independent clause 'is significantly helped by new technologies.' Choice C is a simple sentence with one independent clause: 'In the fight against obesity, countries around the world are imposing taxes on sodas and other sugary drinks in an effort to curb unhealthy habits.' Choice D is a complex sentence with a dependent clause 'Because the assassination of President John F. Kennedy continues to haunt and fascinate Americans' and an independent clause 'new movies, books, and television series about it are released every year.'

3. Which of the following is the main organ responsible for regulating sleep?

A. Thalamus
B. Hypothalamus
C. Pituitary gland
D. Pineal gland

Correct answer: B

Rationale: The main organ responsible for regulating sleep is the hypothalamus. The hypothalamus plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. It receives input from the eyes about light and darkness, aiding in determining when it's time to sleep or wake up. Additionally, the hypothalamus regulates the production of melatonin by the pineal gland, a hormone that helps control sleep patterns. While the thalamus relays sensory information to the brain, the pituitary gland is primarily responsible for hormone production and release, and the pineal gland produces melatonin under the control of the hypothalamus. Therefore, the hypothalamus is the correct choice as the main organ involved in sleep regulation.

4. How will 0.80 be written as a percent?

A. 40%
B. 125%
C. 90%
D. 80%

Correct answer: D

Rationale: To convert a decimal to a percent, you multiply by 100. Therefore, 0.80 * 100 = 80%. The correct answer is D. Choice A (40%) is incorrect as 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as it is greater than 100%. Choice C (90%) is incorrect as it does not reflect the correct conversion of 0.80 to a percent.

5. Hampton was quickly attracted to the Black Panther Party’s approach to the fight for equal rights for African Americans. Which of the following options uses the possessive form correctly?

A. NO CHANGE
B. Black Panther Party's approach
C. Black Panther Party's approach
D. Black Panther Party's approach

Correct answer: A

Rationale: Choice A, 'NO CHANGE,' is the correct answer. 'Party’s' is correctly used to show the possessive form, indicating the approach belongs to the Black Panther Party. Choices B, C, and D incorrectly use plural forms ('Parties' or 'Partys') or unnecessary apostrophes ('Partys’'), which do not accurately convey the possessive form needed in this context.
