1. At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim's house and gives him 6 of his apples. He then uses 3/4 of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?

• A. 4
• B. 6
• C. 2
• D. 1

Correct answer: D

Rationale: Xavier gives away half of his 20 apples (10), then gives 6 more apples, leaving him with 4 apples. He uses 3/4 of the remaining 4 apples (3) for the pie, leaving him with 1 apple at the end of the day. Therefore, the correct answer is 1. Choices A, B, and C are incorrect because they do not accurately reflect the calculations of apples given away and used for the pie, resulting in the remaining amount of 1 apple.

2. Based on a favorable performance review at work, Matt receives a 3/20 increase in his hourly wage. If his original hourly wage is represented by w, which of the following represents his new wage?

• A. 0.15w
• B. 0.85w
• C. 1.12w
• D. 1.15w

Correct answer: D

Rationale: To calculate Matt's new wage after a 3/20 increase, we need to add this percentage increase to his original wage. The increase in decimal form is 3/20 = 0.15. Therefore, the new wage is w + w(0.15) = w(1 + 0.15) = 1.15w. This means the correct answer is D. Choices A, B, and C are incorrect because they do not account for the full 3/20 increase in the wage. Choice A (0.15w) represents only the increase percentage, not the total new wage. Choice B (0.85w) and Choice C (1.12w) do not accurately calculate the new wage after the increase, leading to incorrect representations of the final wage.

3. She is a gifted pianist, although she's struggling with the piece for her upcoming concert.

• A. Inappropriate transition word choice
• B. Poor diction
• C. Tense disagreement
• D. Incomplete sentence

Correct answer: C

Rationale: The correct answer is C because there is a tense disagreement in the sentence. The use of 'was' (past tense) and 'she's' (contraction of 'she is' present tense) creates an inconsistency in the verb tense. The sentence should maintain consistency either in past tense ('She was a gifted pianist, although she struggled with the piece for her upcoming concert') or present tense ('She is a gifted pianist, although she's struggling with the piece for her upcoming concert'). Choices A, B, and D are incorrect as the issue in the sentence is related to verb tense disagreement, not transition words, diction, or sentence completeness.

4. During a healthy heartbeat, the P wave on an ECG represents

• A. The repolarization of the ventricles.
• B. The electrical conduction through the AV node.
• C. The contraction phase of the ventricles (systole).
• D. The depolarization of the atria.

Correct answer: D

Rationale: The P wave on an ECG represents the depolarization of the atria. This electrical activity initiates the contraction of the atria, allowing blood to be pumped into the ventricles. The P wave is the first positive deflection seen on the ECG and signifies the beginning of atrial depolarization, which is a critical step in the cardiac cycle. Choices A, B, and C are incorrect. Option A (The repolarization of the ventricles) is represented by the T wave on the ECG. Option B (The electrical conduction through the AV node) is not represented by the P wave but rather by the PR interval on the ECG. Option C (The contraction phase of the ventricles (systole)) is more related to the QRS complex on the ECG, which represents ventricular depolarization and contraction.

5. Which of the following sentences correctly uses a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. I have a big test tomorrow; I can't go out tonight.
• C. I have a big test tomorrow; and I can't go out tonight.
• D. I have a big test tomorrow; but I can't go out tonight.

Correct answer: A

Rationale: The correct use of a semicolon is to join two closely related independent clauses. Choice A is the only option that correctly uses a semicolon to connect two independent clauses: 'I have a big test tomorrow' and 'I can't go out tonight.' Choice B incorrectly uses a comma instead of a semicolon. Choice C adds an unnecessary 'and' after the semicolon, which disrupts the correct punctuation usage. Choice D introduces a contradictory conjunction 'but' after the semicolon, which is not necessary for the given context. Therefore, the correct answer is A.
