1. Which of the examples uses the correct plural form?

• A. Tomatoes
• B. Analysis
• C. Cacti
• D. Criterion

Correct answer: C

Rationale: The correct plural form of 'cactus' is 'cacti' according to the English language rules for forming plural nouns ending in -us. The word 'cacti' is the plural form of 'cactus,' which follows this particular rule. Choice A 'Tomatoes' is incorrect because the correct plural form of 'tomato' is 'tomatoes,' not 'tomatos.' Choice B 'Analysis' is incorrect as it is already the plural form. Choice D 'Criterion' is incorrect as its plural form is 'criteria,' not 'criterion.'

2. Which of the following units is used to express concentration as a mass of solute per unit volume of solution?

• A. Molality (m)
• B. Molarity (M)
• C. Weight percent (%)
• D. Parts per million (ppm)

Correct answer: A

Rationale: Molality (m) is the unit used to express concentration as a mass of solute per unit volume of solution. It is calculated by dividing the mass of solute in grams by the mass of the solvent in kilograms. Molality is preferred over molarity when there are large temperature variations as it is temperature-independent, making it a more accurate measure of concentration. Molarity (B) is the unit used to express concentration as moles of solute per liter of solution, weight percent (C) is the mass of solute per 100 parts of the total mass of the solution, and parts per million (D) is used to express very small concentrations where 1 ppm is equivalent to 1 mg of solute per liter of solution.

3. Which of the following punctuation marks correctly completes the sentence below? "She bought several items for the trip____ a tent, a sleeping bag, and a flashlight."

• A. ;
• B. :
• C. ,
• D. .

Correct answer: B

Rationale: The correct punctuation mark to use in this sentence is the colon (:) because it is used to introduce a list. In this case, the list of items she bought for the trip includes a tent, a sleeping bag, and a flashlight. A semicolon (;) is not appropriate here because it is typically used to connect independent clauses. A comma (,) is not suitable as it would create a comma splice error. A period (.) is incorrect as it signifies the end of a sentence, which is not the intended purpose in this context.

4. What are the tiny blood vessels that transport blood from arteries to veins within the body?

• A. Arterioles
• B. Capillaries
• C. Venules
• D. Veins

Correct answer: B

Rationale: The correct answer is B: Capillaries. Capillaries are the smallest blood vessels that connect arterioles (small arteries) with venules (small veins). They enable the exchange of oxygen, nutrients, and waste products between the blood and tissues. Arterioles are small arteries that carry blood away from the heart, while venules are small veins that carry blood towards the heart. Veins are larger blood vessels that transport blood back to the heart. Therefore, capillaries specifically serve as the vessels responsible for the exchange of substances between the blood and body tissues.

5. What is the most effective way to rewrite the following sentence: She is saying that some of the students are wearing to school is being distracting and inappropriate?

• A. Some of the outfits students wear to school, she is saying, are distracting and not appropriate.
• B. The outfits are distracting and inappropriate, she says, that students wear to school.
• C. She says that some of the outfits that students wear to school are distracting and inappropriate.
• D. She says that it is distracting and inappropriate that students wear outfits to school.

Correct answer: C

Rationale: The most effective way to rewrite the sentence is, 'She says that some of the outfits that students wear to school are distracting and inappropriate.' This choice corrects the sentence structure by placing the subject ('Some of the outfits') before the verb ('are'), making it clearer and more grammatically correct. Choice A is incorrect as it places the subject after the verb, which disrupts the sentence structure. Choice B is incorrect as it changes the meaning of the sentence by placing the verb before the subject. Choice D is incorrect as it creates a confusing sentence structure by using 'that' redundantly.
