1. What does trypsin break down in the body?

• A. Fat
• B. Starch
• C. Proteins
• D. Nucleic acids

Correct answer: C

Rationale: Trypsin is an enzyme that specifically breaks down proteins into smaller peptides by hydrolyzing peptide bonds. It is a key enzyme involved in the digestion of proteins in the body, particularly in the small intestine where it helps in the final stages of protein digestion. Choices A, B, and D are incorrect because trypsin does not break down fats, starch, or nucleic acids; its primary function is the digestion of proteins.

2. Which is not listed as an example of a low-impact sport?

• A. Martial arts
• B. Basketball
• C. Yoga
• D. Weight lifting

Correct answer: B

Rationale: Basketball is not listed as a low-impact sport in the extract provided; the others (martial arts, yoga, and weight lifting) are considered low-impact activities. The extract mentions that students can participate in low-impact sports like yoga, martial arts, and weight lifting in modern PE classes, emphasizing their benefits and the focus on general skills. Basketball, on the other hand, is not included in the list of low-impact sports mentioned in the extract, making it the correct answer. This demonstrates the importance of understanding the difference between high-impact and low-impact sports for maintaining fitness and health.

3. Which word is not spelled correctly in the context of the following sentence? I like the way the bride’s stationery complements her wedding decor.

• A. bride’s
• B. stationery
• C. complements
• D. decor

Correct answer: C

Rationale: The word 'complements' is not spelled correctly in the context of the sentence. The correct spelling should be 'complements,' which means 'enhances or goes well with.' 'Compliments' in this context would refer to expressions of praise or admiration. The other choices ('bride’s,' 'stationery,' 'decor') are correctly spelled and fit the context of the sentence.

4. How do a scalar quantity and a vector quantity differ?

• A. A scalar quantity has both magnitude and direction, and a vector does not.
• B. A scalar quantity has direction only, and a vector has only magnitude.
• C. A vector has both magnitude and direction, and a scalar quantity has only magnitude.
• D. A vector has only direction, and a scalar quantity has only magnitude.

Correct answer: C

Rationale: The correct answer is C. The main difference between a scalar quantity and a vector quantity lies in the presence of direction. A vector quantity has both magnitude and direction, while a scalar quantity has magnitude only, without any specified direction. Examples of scalar quantities include distance, speed, temperature, and energy, whereas examples of vector quantities include displacement, velocity, force, and acceleration. Choices A, B, and D are incorrect because they incorrectly describe the characteristics of scalar and vector quantities.

5. Divide: 5,117 ÷ 31 =

• A. 109 r3
• B. 115 r14
• C. 133 r5
• D. 165 r2

Correct answer: D

Rationale: When dividing 5,117 by 31, the quotient is 165 with a remainder of 2. The correct answer is 165 r2. Choices A, B, and C are incorrect as they do not reflect the correct division result. Choice A is close but has the wrong remainder. Choices B and C have incorrect quotients and remainders, making them inaccurate. Therefore, the correct answer is D, 165 r2.
