1. Which of the following is the most reliable source for scholarly research?

• A. Peer-reviewed articles
• B. Wikipedia
• C. Opinion articles from a newspaper
• D. Blogs and other social media

Correct answer: A

Rationale: The correct answer is 'Peer-reviewed articles.' Peer-reviewed articles are considered highly reliable because they undergo a rigorous evaluation process by experts in the field before publication. This process ensures that the research presented is of high quality and meets academic standards. Choice B, 'Wikipedia,' is not considered a reliable source for scholarly research as it can be edited by anyone, leading to potential inaccuracies. Choice C, 'Opinion articles from a newspaper,' may provide perspectives but may not always be based on rigorous research or evidence. Choice D, 'Blogs and other social media,' lack the rigorous review process that peer-reviewed articles undergo, making them less reliable for scholarly research.

2. What is the mode of the data set: 2, 3, 3, 4, 4, 4, 5?

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: C

Rationale: The mode of a data set is the value that appears most frequently. In this data set (2, 3, 3, 4, 4, 4, 5), the number 4 appears three times, which is more frequent than any other number in the set. Therefore, the correct answer is 4. Choice A (2), B (3), and D (5) do not appear as frequently as 4 in the data set, so they are not the mode.

3. Which sentence contains a misplaced modifier?

• A. Running through the park, the dog chased me.
• B. I saw the dog running through the park.
• C. The dog chased me through the park.
• D. While running through the park, I saw the dog.

Correct answer: A

Rationale: The correct answer is A. In sentence A, the modifier 'Running through the park' is misplaced because it makes it seem like the dog was the one running through the park rather than the intended meaning that the speaker was running through the park. In choices B, C, and D, the modifiers are correctly placed, providing clear and concise descriptions without causing confusion about who or what is performing the action.

4. Which of the following structures is responsible for transmitting electrical impulses in the nervous system?

• A. Neuron
• B. Axon
• C. Myelin
• D. Dendrite

Correct answer: A

Rationale: The correct answer is A: Neuron. Neurons are specialized cells that transmit electrical impulses in the nervous system. While the axon is the part responsible for conducting these impulses over long distances, it is the neuron as a whole that is ultimately responsible for transmitting electrical impulses. Myelin is a fatty substance that surrounds and insulates axons, speeding up signal transmission. Dendrites, on the other hand, receive signals from other neurons. Therefore, although the axon plays a significant role in transmission, the neuron is the fundamental unit responsible for transmitting electrical impulses in the nervous system.

5. Which decimal is the smallest?

• A. 2.22
• B. 2.02
• C. 2.002
• D. 2.2

Correct answer: C

Rationale: To determine the smallest decimal, we look at the digits after the decimal point. In this case, 2.002 is the smallest because it has the least value in the thousandths place. Choice A, 2.22, has a higher value in the hundredths place making it larger. Choice B, 2.02, has a higher value in the hundredths place compared to 2.002. Choice D, 2.2, is larger than 2.002 as it has a higher value in the tenths place.
