1. Which of the following phrases follows the rules of capitalization?

• A. President Carter and his advisors
• B. Robert Jones, the senior Senator from California
• C. my Aunt and Uncle who live out West
• D. the party on New Year’s Eve

Correct answer: B

Rationale: The correct answer is B. In this phrase, the words 'Senator' and 'California' are capitalized correctly since they refer to a specific position and a proper noun, respectively. 'Senator' is capitalized as it is part of the title and 'California' is capitalized as a proper noun. Choice A is incorrect because 'President' should be capitalized when it precedes a specific name, like 'President Carter.' Choice C is incorrect because 'Aunt' and 'Uncle' are not proper nouns and should not be capitalized. Choice D is incorrect because only 'New Year's Eve' should be capitalized as it is a proper noun for the event.

2. Solve for x in the equation above: (x/y) - z = rw

• A. X = y(z + rw)
• B. X = rw(y - z)
• C. X = rwy + z
• D. X = rwy - z

Correct answer: A

Rationale: To solve for x, first, isolate x by moving the term involving x to one side of the equation. Begin by adding z to both sides of the equation to get (x/y) = rw + z. Then, multiply both sides by y to get x = y(rw + z), which simplifies to x = y(z + rw). Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not correctly rearrange the terms in the equation to solve for x.

3. What does 'mm' stand for in the metric system?

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

4. What is the function of introns in eukaryotic genes?

• A. They code for protein sequences.
• B. They are involved in gene regulation.
• C. They are removed during mRNA processing.
• D. They are non-functional remnants of ancient DNA.

Correct answer: C

Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.

5. What is the most effective way to combine the two sentences below?

• A. German cuisine is known for its hearty meat and potato dishes but families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
• B. German cuisine is known for its hearty meat and potato dishes, but families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
• C. German cuisine is known for its hearty meat and potato dishes and families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
• D. German cuisine is known for its hearty meat and potato dishes, and families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.

Correct answer: D

Rationale: The correct answer is D. This choice effectively combines the two sentences with the use of a comma before 'and' to connect the two related but independent clauses. The comma helps to separate the contrasting information about German cuisine and the Sunday dinner, maintaining a clear and coherent structure. Choices A, B, and C are incorrect because they either lack the necessary punctuation or use 'but' instead of 'and,' which disrupts the flow of the combined sentence and fails to convey the intended relationship between the two ideas.
