1. 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.

2. How many ounces are in 2.5 quarts?

• A. 64 ounces
• B. 40 ounces
• C. 32 ounces
• D. 80 ounces

Correct answer: D

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 2.5 quarts, you multiply 2.5 by 32, which equals 80 ounces. So, the correct answer is 80 ounces. Choice A (64 ounces) is incorrect as it miscalculates the conversion. Choice B (40 ounces) is incorrect as it does not consider the correct conversion factor. Choice C (32 ounces) is incorrect as it provides the conversion for 1 quart only, not for 2.5 quarts.

3. Which sentence is correct?

• A. The physician wrote a prescription for the needed medicine
• B. The physician wrote a recommendation for the needed medicine
• C. The physician wrote a report for the needed medication
• D. The physician wrote a subscription for the needed medication

Correct answer: A

Rationale: A prescription is a written order from a physician or other licensed health practitioner for the preparation and administration of a medication. In this context, 'prescription' is the correct term for the document written by a physician to authorize the dispensing of medication. The other options (B, C, D) use incorrect terms such as 'recommendation,' 'report,' and 'subscription,' which do not accurately convey the action of a physician prescribing medication. Therefore, choice A is the correct answer as it accurately describes the action taken by the physician.

4. A rancher has a herd of different-colored horses in his corral. Ten of the horses are black, six are brown, eight are two-color horses, and three are all white. What percentage of the horses are brown? (Round to the nearest whole number if necessary).

• A. 15%
• B. 20%
• C. 25%
• D. 30%

Correct answer: B

Rationale: To find the percentage of brown horses, first calculate the total number of horses: 10 black + 6 brown + 8 two-color + 3 all white = 27 horses. Then, calculate the percentage of brown horses: (6 ÷ 27) × 100 = 22.22%, which rounds to 20%. Choice B, 20%, is the correct answer. Choice A, 15%, is incorrect as it does not reflect the accurate percentage of brown horses. Choice C, 25%, is incorrect as it overestimates the percentage of brown horses. Choice D, 30%, is incorrect as it also overestimates the percentage of brown horses.

5. Select the meaning of the word 'distended' in the sentence: 'Wracked by abdominal pain, the victim of food poisoning moaned and rubbed his distended belly.'

• A. concave
• B. sore
• C. swollen
• D. empty

Correct answer: C

Rationale: The correct answer is C: 'swollen.' In the context provided, 'distended' refers to the victim's belly being enlarged or bloated due to abdominal pain. This matches the description of the victim moaning and rubbing his belly, indicating discomfort from swelling. Choices A, B, and D are incorrect. 'Concave' means having an inward curve, opposite to the intended meaning. 'Sore' means experiencing pain or discomfort, which is not directly related to the physical enlargement described in the sentence. 'Empty' means containing nothing, which contrasts with the idea of the belly being visibly enlarged or bloated.
