1. Which of the following best explains the meaning of extraneous as it is used in the sentence? The report was filled with extraneous details that had nothing to do with the main findings of the study.

• A. sophisticated
• B. irrelevant
• C. diligent
• D. useful

Correct answer: B

Rationale: The word 'extraneous' means something that is irrelevant or unnecessary to the main topic at hand. In the given sentence, 'extraneous' is used to describe details that are not related to the main findings of the study, indicating that they are unnecessary and irrelevant. Therefore, 'irrelevant' is the correct explanation. Choices 'sophisticated,' 'diligent,' and 'useful' do not convey the concept of being unnecessary or unrelated, making them incorrect in the context of the sentence.

2. Based on the contextual usage of this word, what is the most likely meaning of the prefix ante-?

• A. again
• B. good
• C. before
• D. together

Correct answer: C

Rationale: The prefix 'ante-' is commonly used to refer to something that comes before something else in terms of time, order, or position. In the provided sentence, the antechamber is described as a waiting area 'before' guests were allowed into the main hall. This usage indicates that 'ante-' in this context means 'before.' The other choices are incorrect: 'again' implies repetition, 'good' is unrelated, and 'together' does not fit the context of preceding or coming before something else.

3. What is the purpose of an electrocardiogram?

• A. Indicate the rate of blood flow
• B. Display the heart's rate and rhythm
• C. Identify a person's blood group type
• D. Determine cell type in a blood sample

Correct answer: B

Rationale: An electrocardiogram (ECG or EKG) is used to measure and display the heart's rate and rhythm. It provides valuable information about the electrical activity of the heart, allowing healthcare providers to assess the heart's health, detect abnormalities in the heart's rhythm, and diagnose various cardiac conditions. Choices A, C, and D are incorrect. Choice A is incorrect because an ECG does not indicate the rate of blood flow but rather focuses on the heart's electrical activity. Choice C is incorrect because identifying a person's blood group type is typically done through blood typing tests, not ECG. Choice D is incorrect because determining cell type in a blood sample is unrelated to the purpose of an ECG.

4. What is the result of multiplying 0.15 by 60?

• A. 9
• B. 15
• C. 45
• D. 60

Correct answer: A

Rationale: The correct answer is A: 9. To find the result of multiplying 0.15 by 60, you simply multiply the two numbers together. 0.15 * 60 = 9. This calculation involves basic multiplication. Choices B, C, and D are incorrect as they do not reflect the correct product of 0.15 and 60. Understanding how to multiply decimals and whole numbers is essential in various real-life scenarios such as calculating percentages or adjusting measurements.

5. Which of the following describes a situation in which research results are consistent with every subsequent experiment, but the test used in the experiment does not measure what it claims to measure?

• A. reliable, but not valid
• B. valid, but not reliable
• C. neither reliable nor valid
• D. both reliable and valid

Correct answer: A

Rationale: The correct answer is A, 'reliable, but not valid.' In this scenario, the research results are consistent in every subsequent experiment, indicating reliability. However, the test used does not measure what it claims to measure, leading to a lack of validity in the results. Choice B, 'valid, but not reliable,' would imply that the test consistently measures what it claims but the results are not consistent, which is not the case here. Choice C, 'neither reliable nor valid,' would suggest that the results are neither consistent nor relevant, which does not align with the provided scenario. Choice D, 'both reliable and valid,' would mean that the results are consistent and measure what they claim to measure, which contradicts the situation described in the question.
