1. What is a pentose sugar?

• A. A 6 carbon sugar
• B. A 4 carbon sugar
• C. A 5 carbon sugar
• D. A 7 carbon sugar

Correct answer: C

Rationale: A pentose is a 5-carbon sugar, as the prefix 'pent-' signifies five. Therefore, a pentose sugar consists of five carbon atoms. Choice A, 'A 6 carbon sugar,' is incorrect as a pentose sugar specifically has five carbons. Choice B, 'A 4 carbon sugar,' is incorrect as it describes a tetrose sugar, which has four carbons. Choice D, 'A 7 carbon sugar,' is incorrect as it does not correspond to the definition of a pentose sugar.

2. The jawbone may be called the ___________.

• A. mantis
• B. mantua
• C. mandible
• D. manganite

Correct answer: C

Rationale: The jawbone is commonly referred to as the mandible in anatomy. It is the largest and strongest bone in the human face and forms the lower jaw, holding the lower teeth in place. "Mandible" is the correct anatomical term for this specific bone structure.

3. What word is best to substitute for the underlined words in the following sentence? The children loved having their photographs taken.

• A. its
• B. their
• C. they
• D. his

Correct answer: B

Rationale: The correct word to substitute for the underlined words 'the children' in the sentence would be 'their' to ensure clarity and proper possessive form. Using 'their' makes it clear that the photographs belong to the children. Choice A 'its' is incorrect as it refers to singular possession. Choice C 'they' is a pronoun and does not indicate possession. Choice D 'his' is incorrect as it is singular and refers to a male possessive form, which does not match the plural 'children' in the sentence.

4. Which of the following is spelled correctly?

• A. Embarrassing
• B. Embarrasing
• C. Embarrassing
• D. Emberassing

Correct answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.

5. Ratio and proportion: 6:10=24:x

• A. 40
• B. 25
• C. 240
• D. 4

Correct answer: A

Rationale: To solve for x, use cross-multiplication: 6x = 10 x 24 6x = 240 Now, divide both sides by 6 to find x: x = 240 / 6 = 40 Therefore, the correct answer is A. 40. Choice B, 25, is incorrect because it does not satisfy the proportion. Choice C, 240, is incorrect because it represents the value that is given in the proportion and not the value of x. Choice D, 4, is incorrect as it does not align with the correct calculation for x.
