1. A rectangular solid box has a square base with a side length of 5 feet and a height of h feet. If the volume of the box is 200 cubic feet, which of the following equations can be used to find h?

• A. 5h = 200
• B. 5h² = 200
• C. 25h = 200
• D. h = 200 ÷ 5

Correct answer: C

Rationale: The volume formula for a rectangular solid is V = l × w × h. In this case, the length and width are both 5 feet. Substituting the values into the formula gives V = 5 × 5 × h = 25h = 200. Therefore, h = 200 ÷ 25 = 8. Option A is incorrect because the product of length, width, and height is not directly equal to the volume. Option B is incorrect as squaring the height is not part of the volume formula. Option D is incorrect as it oversimplifies the relationship between height and volume, not considering the base dimensions.

2. Calculate the sum of the numbers from 1 to 6:

• A. 30
• B. 21
• C. 15
• D. 13

Correct answer: B

Rationale: To find the sum of numbers from 1 to 6, we add them together: 1 + 2 + 3 + 4 + 5 + 6 = 21. Therefore, the correct answer is 21. Choice A (30) is incorrect because it is not the sum of the numbers 1 to 6. Choice C (15) is incorrect as it is the sum of numbers 1 to 5. Choice D (13) is incorrect as it is the sum of numbers 1 to 4, not 1 to 6.

3. Identify the incorrect usage of punctuation in the following sentence: 'The children, eager to play, ran outside; it was a beautiful day.'

• A. comma after 'children'
• B. comma after 'play'
• C. period after 'outside'
• D. no errors

Correct answer: C

Rationale: The sentence contains two independent clauses that should be separated by a semicolon or period, not a comma. The incorrect punctuation is the period after 'outside.' A period or semicolon is needed to correctly separate the two independent clauses. The comma after 'children' and 'play' are correctly used to set off non-essential participial phrases. Choice D is incorrect as there is a punctuation error in the sentence.

4. Choose the correctly punctuated sentence.

• A. Its a beautiful day outside.
• B. It's a beautiful day outside.
• C. Its' a beautiful day outside.
• D. It is' a beautiful day outside.

Correct answer: B

Rationale: The correct answer is B: 'It's a beautiful day outside.' 'It's' is the contraction for 'it is.' Choice A is incorrect as it should be 'It's' instead of 'Its.' Choice C is incorrect as the apostrophe should come before the 's' in the contraction. Choice D is incorrect as the use of 'is'' is grammatically incorrect.

5. What function do ribosomes serve within the cell?

• A. Ribosomes are responsible for cell movement.
• B. Ribosomes aid in protein synthesis.
• C. Ribosomes help protect the cell from its environment.
• D. Ribosomes have enzymes that help with digestion.

Correct answer: B

Rationale: Ribosomes serve a crucial role in protein synthesis by translating mRNA into proteins. They are not involved in cell movement, protecting the cell from the environment, or aiding in digestion. Choice A is incorrect because ribosomes are not responsible for cell movement. Choice C is incorrect because ribosomes do not primarily protect the cell from its environment. Choice D is incorrect because ribosomes do not have enzymes that aid in digestion.
