1. Which property of a wave is measured in Hertz (Hz)?

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

Correct answer: D

Rationale: Frequency is the property of a wave that is measured in Hertz (Hz). It represents the number of complete cycles of the wave that occur in one second. Amplitude refers to the height of the wave, wavelength is the distance between two consecutive points on a wave that are in phase, and speed is the rate at which the wave travels through a medium. Therefore, the correct answer is frequency as it directly corresponds to the unit Hertz (Hz) used to measure the number of wave cycles per second.

2. Pernell received the following scores on five exams: 81, 92, 87, 89, and 94. What is the approximate average of these scores?

• A. 81
• B. 84
• C. 89
• D. 91

Correct answer: C

Rationale: To calculate the average of Pernell's scores, add all the scores together and then divide by the number of scores. (81 + 92 + 87 + 89 + 94) = 443. Now, divide 443 by 5: 443 ÷ 5 = 89, which is the average score.

3. Based on the context, which of the following is the meaning of the word match in the sentence?

• A. a competitive event
• B. a suitable pair
• C. a slender piece of wood used to start a fire
• D. a prospective marriage partner

Correct answer: A

Rationale: In the context of the sentence, the word 'match' refers to a competitive event, likely a sports match or game that Victoria participated in and won easily. This is the most appropriate interpretation based on the context provided. Choices B, C, and D are incorrect as they do not fit the context of the sentence. 'A suitable pair,' 'a slender piece of wood used to start a fire,' and 'a prospective marriage partner' do not relate to Victoria winning a match in a sports context.

4. What is the outermost protective layer of the kidney?

• A. Renal cortex
• B. Renal medulla
• C. Renal capsule
• D. Renal pelvis

Correct answer: C

Rationale: The correct answer is C, Renal capsule. The renal capsule is the outermost protective layer of the kidney. It is a tough fibrous layer that surrounds the kidney and helps protect it from injury and maintain its shape. Choice A, Renal cortex, is the outer region of the kidney where filtration occurs. Choice B, Renal medulla, is the inner region of the kidney where urine is formed. Choice D, Renal pelvis, is the funnel-shaped structure that collects urine from the kidney and funnels it into the ureter. Therefore, the renal capsule is specifically designated as the outermost protective layer of the kidney.

5. Many _____ books are popular among adults these days.

• A. Children's
• B. Childrens's
• C. Childrens'
• D. Childrens

Correct answer: A

Rationale: The correct answer is 'Children's.' In this context, 'Children's' is the correct possessive form to indicate that the books belong to or are associated with children. Choice B ('Childrens's') is incorrect due to the unnecessary extra 's' after the apostrophe. Choice C ('Childrens'') is wrong as it is missing the apostrophe to show possession. Choice D ('Childrens') is incorrect as it is missing the apostrophe and does not form the possessive form correctly.
