1. Select the phrase that will make the following sentence grammatically correct. Dr. Johnson had a serious look when he _________.

• A. spoke to the patient’s parents
• B. is speaking to the patient’s parents
• C. will speak to the patient’s parents
• D. has spoken to the patient’s parents

Correct answer: A

Rationale: The correct answer is 'A - spoke to the patient’s parents.' In this sentence, the past tense 'spoke' should be used to match the past tense 'had,' indicating an action that already took place. Choices B, C, and D are incorrect because they use present or future tenses, which do not match the past tense 'had' in the sentence.

2. Which part of the brain monitors and controls the body's movement?

• A. Top, middle portion of the parietal lobe
• B. Back of the head
• C. Front portion of the parietal lobe
• D. Around the auditory cortex

Correct answer: C

Rationale: The correct answer is the front portion of the parietal lobe. The motor cortex, located in this area, is responsible for planning, controlling, and executing voluntary movements. It plays a crucial role in coordinating the body's movement. Choice A, the top, middle portion of the parietal lobe, is incorrect as this region is more involved in processing sensory information rather than controlling movement. Choice B, the back of the head, is incorrect as it typically refers to the occipital lobe responsible for processing visual information. Choice D, around the auditory cortex, is incorrect as the auditory cortex is primarily involved in processing auditory information, not controlling body movement.

3. Which substance causes a drop to rapidly turn litmus dye from blue to red?

• A. Milk
• B. Sea water
• C. Ammonia
• D. Lemon juice

Correct answer: D

Rationale: Lemon juice is the correct answer as it is acidic in nature. Acids like lemon juice release hydrogen ions when dissolved in water, which causes litmus dye to change color from blue to red. Milk (Choice A) is neutral, sea water (Choice B) is slightly alkaline, and ammonia (Choice C) is a base. Therefore, these substances do not cause litmus dye to change from blue to red.

4. What is the chemical reaction that involves breaking down a compound into component parts?

• A. Decomposition
• B. Synthesis
• C. Combustion
• D. Single replacement

Correct answer: A

Rationale: Decomposition is the correct answer because in a decomposition reaction, a compound is broken down into simpler substances. This type of reaction involves the splitting of a compound into its component parts, often through the use of heat, light, or electricity. Synthesis (choice B) is the opposite process where simpler substances are combined to form a more complex compound. Combustion (choice C) is a reaction involving rapid oxidation often accompanied by heat and light. Single replacement (choice D) is a reaction where one element replaces another in a compound.

5. How many ounces are in 4.5 quarts?

• A. 120 ounces
• B. 120 ounces
• C. 144 ounces
• D. 128 ounces

Correct answer: C

Rationale: There are 32 ounces in a quart, so to find out how many ounces are in 4.5 quarts, you need to multiply 4.5 by 32. 4.5 quarts * 32 ounces/quart = 144 ounces. Therefore, the correct answer is 144 ounces. Choices A, B, and D are incorrect because they do not correctly calculate the conversion from quarts to ounces.
