1. Which sentence uses correct punctuation?

• A. I cooked so I could eat dinner.
• B. I cooked so, I could eat dinner.
• C. I cooked so I, could eat dinner.
• D. I cooked, so I could eat dinner.

Correct answer: D

Rationale: The correct answer is sentence D: 'I cooked, so I could eat dinner.' This sentence uses a comma correctly to separate two independent clauses, 'I cooked,' and 'so I could eat dinner.' Choice A is incorrect as it lacks punctuation to separate the clauses properly. Choice B incorrectly uses a comma after 'so,' disrupting the flow of the sentence. Choice C incorrectly places a comma after 'I,' which is not needed in this context.

2. After a hurricane struck a Pacific island, donations began flooding into a disaster relief organization. The organization provided four options for donors. What percentage of the funds was donated to support construction costs?

• A. 49%
• B. 23%
• C. 18%
• D. 10%

Correct answer: B

Rationale: The correct answer is B (23%). The information was obtained from the pie chart which indicated that 23% of the funds were allocated to support construction costs. Choice A (49%), Choice C (18%), and Choice D (10%) are incorrect as they do not reflect the accurate percentage designated for construction costs according to the data provided.

3. Which of the following equations does not represent a function?

• A. y = x^2
• B. y = sqrt(x)
• C. x = y^2
• D. y = 2x + 1

Correct answer: C

Rationale: An equation represents a function if each input (x-value) corresponds to exactly one output (y-value). In the equation x = y^2, for a single x-value, there are two possible y-values (positive and negative square root), violating the definition of a function. This violates the vertical line test, where a vertical line intersects the graph in more than one point for non-functions. Choices A, B, and D all pass the vertical line test and represent functions, making them incorrect answers.

4. Glial cells support and protect neurons within the central and peripheral nervous system. What are they called?

• A. Astrocytes
• B. Neuroglia
• C. Oligodendrocytes
• D. Schwann cells

Correct answer: A

Rationale: Astrocytes are a type of glial cell that provide support and protection for neurons in both the central and peripheral nervous systems. While the term 'Neuroglia' is often used to refer to glial cells collectively, in this context, the question specifically asks for the name of the cells, making 'Astrocytes' the correct answer. Choice B, 'Neuroglia,' is a general term for all glial cells, not a specific type. Choices C and D, 'Oligodendrocytes' and 'Schwann cells,' are also types of glial cells but are not the primary cells responsible for supporting and protecting neurons as described in the question.

5. In the sentence 'The cherry tomatoes in our backyard are finally ready to be picked,' which of the following is the complete subject?

• A. tomatoes
• B. ready to be picked
• C. The cherry tomatoes in our backyard
• D. finally ready

Correct answer: C

Rationale: The complete subject in a sentence refers to the noun or pronoun that the sentence is about. In this case, the complete subject is 'The cherry tomatoes in our backyard.' It includes all the words that describe the subject and provide more specific information about it. 'Tomatoes' (Choice A) is just a part of the complete subject and not the entire subject. 'Ready to be picked' (Choice B) is a verb phrase, not the subject of the sentence. 'Finally ready' (Choice D) is an adjective phrase, not the subject of the sentence. Therefore, the correct choice is 'The cherry tomatoes in our backyard.'
