1. What is the ratio of women to the total number of students in the class?

• A. 4:7
• B. 16:28
• C. 3:5
• D. 2:3

Correct answer: A

Rationale: To find the ratio of women to the total number of students, you need to simplify the ratio of 16:28. By dividing both numbers by the greatest common factor, which is 4, you get 4:7. Therefore, the correct ratio of women to the total number of students is 4:7. Choice A is correct. Choices C and D are incorrect because they do not represent a valid ratio. Choice B is the original ratio given in the question, which should be simplified to 4:7 as explained in the rationale.

2. How many ounces are in 2.5 gallons?

• A. 240 ounces
• B. 160 ounces
• C. 320 ounces
• D. 240 ounces

Correct answer: C

Rationale: To convert gallons to ounces, we need to know that 1 gallon is equal to 128 ounces. Therefore, 2.5 gallons would be 2.5 x 128 = 320 ounces. This makes choice C, '320 ounces,' the correct answer. Choices A, B, and D are incorrect because they do not correctly calculate the conversion from gallons to ounces.

3. Select the meaning of the underlined word in the following sentence. The chemicals in plastic containers may be deleterious to children’s health.

• A. Harmful
• B. Deleting
• C. Delightful
• D. Inoffensive

Correct answer: A

Rationale: The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.

4. Divide: 727 ÷ 6 =

• A. 120 r1
• B. 120 r3
• C. 121 r1
• D. 127 r3

Correct answer: C

Rationale: When dividing 727 by 6, the quotient is 121 with a remainder of 1. The correct answer is, therefore, 121 r1. Choice A (120 r1) is incorrect as the quotient is 121, not 120. Choice B (120 r3) is also incorrect as the remainder should be 1, not 3. Choice D (127 r3) is incorrect as both the quotient and remainder are different from the correct values obtained by dividing 727 by 6.

5. What type of transport moves substances across the cell membrane using energy?

• A. Passive Transport
• B. Active Transport
• C. Facilitated Diffusion
• D. Osmosis

Correct answer: B

Rationale: The correct answer is B: Active Transport. Active transport moves substances across the cell membrane by utilizing energy from the cell, typically in the form of ATP. This process allows the cell to move molecules against their concentration gradient, requiring energy expenditure. Choices A, C, and D are incorrect because passive transport does not require energy input, facilitated diffusion involves the assistance of proteins but does not directly use energy, and osmosis is the diffusion of water molecules specifically, not substances, across a selectively permeable membrane.
