1. What percentage of rainfall received during this timeframe is received during the month of October?

• A. 13.50%
• B. 15.10%
• C. 16.90%
• D. 17.7%

Correct answer: D

Rationale: To determine the percentage of rainfall received during the month of October, we must first calculate the total rainfall for October and the total rainfall for the entire timeframe. Given that the total rainfall for October is 18.9 inches and the total rainfall from January to November is 106.3 inches, we can proceed with the calculation. The percentage is calculated as (18.9/106.3) x 100 = 17.7%. Therefore, the correct answer is D, 17.7%. Choice A (13.50%), Choice B (15.10%), and Choice C (16.90%) are incorrect as they do not align with the accurate calculation based on the provided data.

2. How many milliliters are in 0.5 liters?

• A. 50 mL
• B. 500 mL
• C. 5,000 mL
• D. 5 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 0.5 liters x 1000 = 500 milliliters, making choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters.

3. What kind of error does the following sentence contain? Forgetting that he was supposed to meet his girlfriend for dinner, Anita was mad when Fred showed up late.

• A. Parallelism
• B. Run-on sentence
• C. Misplaced modifier
• D. Subject-verb agreement

Correct answer: C

Rationale: The correct answer is C, misplaced modifier. In this sentence, the modifier 'Forgetting that he was supposed to meet his girlfriend for dinner' is placed incorrectly, suggesting that Anita forgot, when it was actually Fred who forgot. The modifier should be positioned closer to 'Fred' to clarify the intended meaning. Choices A, B, and D are incorrect. Parallelism is not an issue in this sentence, it is not a run-on sentence as it is grammatically correct, and there is no subject-verb agreement error present.

4. Which of the following chambers of the heart receives blood returning from the lungs during pulmonary circulation?

• A. left atrium
• B. right atrium
• C. left ventricle
• D. right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. During pulmonary circulation, oxygenated blood returns from the lungs to the heart and enters the left atrium through the pulmonary veins. The left atrium then contracts, pushing this oxygen-rich blood into the left ventricle. The left ventricle subsequently pumps this oxygenated blood out to the rest of the body through the aorta. Choices B, C, and D are incorrect because the right atrium receives deoxygenated blood from the body, the left ventricle receives oxygenated blood from the left atrium, and the right ventricle pumps deoxygenated blood to the lungs for oxygenation, respectively.

5. What property of a wave determines its pitch in sound waves?

• A. Amplitude
• B. Frequency
• C. Wavelength
• D. Speed

Correct answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency is the number of cycles of a wave that occur in a given time period. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the intensity or loudness of a sound wave, wavelength is the distance between two consecutive points in a wave, and speed is the rate at which a wave travels through a medium. Therefore, in sound waves, it is the frequency that primarily determines the pitch, making option B the correct answer.
