1. What defines the period of a wave?

• A. The time it takes for one complete wave cycle to pass a point
• B. The distance between two adjacent crests or troughs
• C. The number of waves passing a point per unit time
• D. The maximum displacement of particles in a medium due to the wave

Correct answer: A

Rationale: The period of a wave is defined as the time it takes for one complete wave cycle to pass a point. It is a crucial parameter in wave analysis and is typically measured in seconds. The period is directly related to the frequency of the wave, as they are reciprocals of each other. Therefore, the correct answer is the time it takes for one complete wave cycle to pass a point (choice A). The period is not related to the number of waves passing a point per unit time (choice C), the distance between two adjacent crests or troughs (choice B), or the maximum displacement of particles in a medium due to the wave (choice D).

2. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

3. Hampton was born and raised in Maywood of Chicago, Illinois in 1948. Which of the following is the correct punctuation for the sentence?

• A. NO CHANGE
• B. in Maywood, of Chicago, Illinois in 1948.
• C. in Maywood of Chicago, Illinois, in 1948.
• D. in Chicago, Illinois of Maywood in 1948.

Correct answer: C

Rationale: Option C correctly punctuates the sentence by placing commas after 'Chicago' and 'Illinois' to separate the location details and inserting a comma before 'in 1948' to separate the location from the date. This creates a clear and grammatically correct sentence. Choices A, B, and D incorrectly place the commas, leading to confusion or incorrect grouping of the location and date information.

4. Which of the following is an example of a chemical change?

• A. Dissolving sugar in water
• B. Boiling water
• C. Rusting iron
• D. Crushing ice

Correct answer: C

Rationale: Rusting iron is an example of a chemical change because it involves a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). This reaction results in a change in the chemical composition of the iron, unlike dissolving sugar in water, boiling water, or crushing ice, which are physical changes. Dissolving sugar in water is a physical change as sugar molecules remain unchanged but disperse in water. Boiling water is also a physical change as water changes its state from liquid to gas due to heat. Crushing ice is a physical change as the solid ice changes its physical form without altering its chemical composition.

5. Which of the following is an appropriately-punctuated correction for this sentence: Protestors filled the streets of the city because they were dissatisfied with the government's leadership?

• A. Protestors filled the streets of the city, because they were dissatisfied with the government's leadership.
• B. Protesters, filled the streets of the city, because they were dissatisfied with the government's leadership.
• C. Because they were dissatisfied with the government's leadership protestors filled the streets of the city.
• D. Protestors filled the streets of the city because they were dissatisfied with the government's leadership.

Correct answer: D

Rationale: The correct answer is D. The sentence should be corrected by removing the period and joining the clauses to avoid a sentence fragment. Choice A is incorrect due to the unnecessary comma after 'city.' Choice B is incorrect as it mistakenly separates the subject and verb with a comma. Choice C is incorrect as it begins with the subordinate clause, disrupting the logical flow of the sentence.
