1. What is a common denominator?

• A. A shared multiple of two denominators
• B. A shared factor of two numerators
• C. A number that is the same in all fractions
• D. A number that divides evenly into both fractions

Correct answer: A

Rationale: A common denominator is a shared multiple of the denominators in a set of fractions. It is necessary when adding or subtracting fractions to have a common denominator to ensure that the fractions can be combined accurately. Choice B is incorrect because the common denominator is related to the denominators, not the numerators. Choice C is incorrect because while the common denominator is the same in all fractions being added or subtracted, it is not necessarily a number that is the same in all fractions. Choice D is incorrect because a common denominator is a multiple of the denominators, not a number that divides evenly into both fractions.

2. Which of the following sentences correctly uses a transition word?

• A. Gilda is a hardworking student; therefore, she earned a good grade on her essay.
• B. Gilda is a hardworking student; therefore she earned a good grade on her essay.
• C. Gilda is a hardworking student: therefore, she earned a good grade on her essay.
• D. Gilda is a hardworking student and therefore she earned a good grade on her essay.

Correct answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

3. Consider the graph representing a botanist's data on root growth. What is the independent variable?

• A. Temperature
• B. Root tissue
• C. Light exposure
• D. Root length

Correct answer: C

Rationale: The independent variable is the factor that is intentionally changed or manipulated by the researcher. In this case, light exposure is the independent variable because it is being controlled and tested to observe its effect on root growth. Choices A, B, and D are not the independent variable in this scenario. Temperature, root tissue, and root length are likely dependent variables that could be influenced by the changes in light exposure.

4. Which technique best helps maintain consistency in writing style?

• A. Writing freely without a clear outline or structure.
• B. Using different vocabulary and sentence structures in each paragraph.
• C. Establishing a style guide with agreed-upon terminology and formatting.
• D. Relying on thesaurus suggestions for varied word choices.

Correct answer: C

Rationale: Establishing a style guide with agreed-upon terminology and formatting is the most effective technique to maintain consistency in writing style. A style guide ensures that writers adhere to specific guidelines regarding tone, terminology, and formatting, thereby creating a cohesive and uniform writing style across different pieces of writing. This consistency helps enhance readability and reinforces the brand or voice associated with the written content. Choices A, B, and D are incorrect because they do not promote consistency in writing style. Writing freely without structure can lead to inconsistency, using different vocabulary and sentence structures can create disjointed writing, and relying solely on thesaurus suggestions may result in awkward or inappropriate word choices that do not contribute to maintaining a consistent writing style.

5. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C correctly places the participle phrase 'Reading the book' directly in front of the subject 'I,' ensuring that there is no dangling modifier. This structure establishes a clear connection between the action described in the introductory phrase and the subject performing the action, resulting in a grammatically correct sentence. Choice A, B, and D have dangling modifiers. In choice A, the phrase 'Walking down the street' should be followed by the noun it is describing to avoid the dangling modifier. Choice B has a dangling modifier as 'Having finished the report' does not have a clear subject to relate to. Choice D also has a dangling modifier as 'Exhausted from the hike' is not properly connected to the subject in the sentence.
