1. If she had $1,070 after spending $18, how much did she have initially?

• A. $1,052
• B. $1,060
• C. $1,071
• D. $1,075

Correct answer: A

Rationale: To determine the initial amount she had, we subtract the amount spent ($18) from the total amount she had after spending. If she had $1,070 after spending, subtracting $18 gives us $1,052, which was the initial amount. Choices B, C, and D are incorrect as they do not consider the subtraction of the amount spent to find the initial amount.

2. What is the function of the skin in protecting the body?

• A. To produce vitamin D
• B. To protect against pathogens
• C. To store nutrients
• D. To regulate body temperature

Correct answer: B

Rationale: The skin serves several crucial functions in protecting the body. One of its primary roles is to act as a physical barrier against pathogens, preventing harmful microorganisms from entering the body. Choice A, 'To produce vitamin D,' is incorrect because while the skin is involved in vitamin D synthesis upon exposure to sunlight, its primary protective role is against pathogens. Choice C, 'To store nutrients,' is incorrect as the skin is not a primary organ for nutrient storage. Choice D, 'To regulate body temperature,' is a function of the skin, but the primary role in protecting the body is to act as a barrier against pathogens.

3. In Einstein’s mass-energy equation, what is represented by c?

• A. Distance in centimeters
• B. The speed of light
• C. Degrees Celsius
• D. Centrifugal force

Correct answer: B

Rationale: In Einstein's mass-energy equation, E=mc^2, the symbol 'c' represents the speed of light in a vacuum, which is approximately equal to 3.00 x 10^8 meters per second. This equation demonstrates the equivalence of energy (E) and mass (m) and is a fundamental concept in the theory of relativity. Choice A is incorrect as 'c' does not represent distance in centimeters. Choice C is incorrect as 'c' does not represent degrees Celsius. Choice D is incorrect as 'c' does not represent centrifugal force.

4. What punctuation is needed in this sentence to make it correct? I will check the supply closet, and you can look in the laundry.

• A. Period
• B. Comma
• C. Colon
• D. Semicolon

Correct answer: B

Rationale: The correct answer is B: 'Comma.' In the sentence, a comma is needed to separate the independent clauses 'I will check the supply closet' and 'you can look in the laundry.' This comma helps to indicate a pause between the two related but separate actions that each person is taking. Choice A (Period) is incorrect because a period would create two separate sentences. Choice C (Colon) is incorrect as a colon is used to introduce a list or explanation. Choice D (Semicolon) is incorrect as a semicolon is used to connect two closely related independent clauses without a coordinating conjunction.

5. What punctuation is needed in the following sentence to make it correct? Do not be afraid to ask questions in his class, he is very approachable and explains things well.

• A. Hyphen
• B. Comma
• C. Apostrophe
• D. Semicolon

Correct answer: B

Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.
