1. Which of the following is a structure found in the upper respiratory tract?

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Esophagus

Correct answer: A

Rationale: The pharynx is a structure found in the upper respiratory tract. It serves as a common pathway for both air and food, playing a crucial role in directing air to the trachea and food to the esophagus. The larynx, trachea, and esophagus are important structures in the respiratory and digestive systems, but the pharynx specifically belongs to the upper respiratory tract, making it the correct answer.

2. Choose the best description for the term 'selected plants' in the following sentence: 'Saturated fat comes principally from animal food products and selected plants.'

• A. Plants that have been chosen
• B. Particular plants
• C. Top quality plants
• D. Restricted plants

Correct answer: B

Rationale: The term 'selected plants' in this sentence refers to specific or particular plants that have been chosen intentionally for some reason. It implies that not all plants contribute to saturated fat but only specific ones. The term 'particular plants' best captures this meaning in the context provided. Choices A, C, and D are incorrect because 'selected plants' does not necessarily imply they are of top quality, plants that have been restricted, or chosen without reason. The emphasis is on the specificity of the plants chosen, making 'particular plants' the most suitable description.

3. What is the function of amylase?

• A. Breaking down starch
• B. Digesting fat
• C. Breaking down protein
• D. Absorbing water

Correct answer: A

Rationale: The correct answer is A: Breaking down starch. Amylase is an enzyme that specifically functions to break down starch into smaller sugar molecules such as maltose and glucose. This process is essential for the digestion and absorption of carbohydrates in the body. Choices B, C, and D are incorrect because amylase does not digest fat, break down protein, or absorb water; its primary function lies in starch digestion.

4. Which state of matter has a definite volume but takes the shape of its container?

• A. Gas
• B. Liquid
• C. Solid
• D. Plasma

Correct answer: B

Rationale: The state of matter that has a definite volume but takes the shape of its container is a 'Liquid.' Liquids have a fixed volume but can change their shape to fit the container they are in. This property distinguishes liquids from solids, which have both a definite shape and volume, and gases, which do not have a fixed volume or shape. Therefore, the correct answer is 'Liquid.' Choice A, 'Gas,' is incorrect because gases do not have a definite volume or shape. Choice C, 'Solid,' is incorrect as solids have a definite shape and volume. Choice D, 'Plasma,' is incorrect because plasma is a state of matter where atoms have been ionized and do not have a fixed volume or shape.

5. Which sentence uses 'fast' as an adverb?

• A. The cars on the overpass moved fast.
• B. The clock on the wall is 10 minutes fast.
• C. The batter could not hit the fast pitch.
• D. The fast cars drove over the bridge.

Correct answer: A

Rationale: In sentence A, 'fast' is used as an adverb to modify the verb 'moved,' describing how the cars moved quickly. Choices B, C, and D use 'fast' as an adjective, describing the clock, pitch, and cars respectively. Adverbs modify verbs, adjectives, or other adverbs, while adjectives modify nouns or pronouns.
