1. Which of the following punctuation marks is used incorrectly in the sentence below?

• A. The semicolon after 'book.'
• B. The comma after 'long.'
• C. The comma after 'glasses.'
• D. The period at the end of the sentence.

Correct answer: C

Rationale: The comma after 'glasses' is used incorrectly in the sentence. Commas are not needed to separate the subject from the verb in this context. In this case, the subject 'She' is not separated from the verb 'wore,' making the comma unnecessary. The semicolon after 'book' is appropriate for separating two independent clauses, the comma after 'long' is correctly used for introductory elements, and the period at the end of the sentence is necessary for indicating the end of a complete thought.

2. How many mcg are there in 0.2 mg?

• A. 20 mcg
• B. 200 mcg
• C. 2000 mcg
• D. 2 mcg

Correct answer: B

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.2 mg is equivalent to 200 mcg. It is crucial to understand this conversion to ensure precise medication dosages. Choice A is incorrect because it does not account for the conversion factor of 1000 between milligrams and micrograms. Choice C is incorrect as it represents the conversion of grams to micrograms. Choice D is incorrect as it does not consider the conversion factor from milligrams to micrograms.

3. On which day of the week will they be able to water their lawn?

• A. Tuesday
• B. Wednesday
• C. Thursday
• D. Saturday

Correct answer: B

Rationale: Based on the town's watering schedule, residents with addresses ending in 7 should water their lawns on Wednesdays. The Morgan family's address ends in 7, so they should set up their watering schedule for Wednesdays. Therefore, the correct answer is Wednesday. Choices A, C, and D are incorrect as they correspond to days designated for addresses ending in other numbers according to the town's schedule.

4. What is insulin, where is it produced, and what is its function?

• A. Produced in the liver, regulates fat storage
• B. Produced in the pancreas, regulates blood sugar
• C. Produced in the stomach, aids in digestion
• D. Produced in the kidneys, controls hydration

Correct answer: B

Rationale: Insulin is a hormone produced in the pancreas. Its primary function is to regulate blood sugar levels by facilitating the uptake of glucose by cells for energy. The other choices are incorrect as insulin is not produced in the liver (Choice A), stomach (Choice C), or kidneys (Choice D), and its function is not related to fat storage, digestion, or hydration. Therefore, the correct answer is B.

5. A car dealership’s commercials claim that this year’s models are 20% off the list price, plus they will pay the first 3 monthly payments. If a car is listed for $26,580, and the monthly payments are set at $250, what is the total potential savings?

• A. $1,282
• B. $5,566
• C. $6,066
• D. $20,514

Correct answer: C

Rationale: To calculate the total potential savings: First, find the 20% discount on the list price of $26,580: 0.20 × $26,580 = $5,316. Then, determine the savings over the first 3 months of payments: 3 months × $250/month = $750. Add the discount and the monthly payment savings to get the total potential savings: $5,316 + $750 = $6,066. Therefore, the correct answer is $6,066. Choice A, $1,282, is incorrect because it does not account for the total savings from both the discount and the monthly payments. Choice B, $5,566, is incorrect as it miscalculates the total savings by excluding the savings from the monthly payments. Choice D, $20,514, is incorrect as it does not consider the discount and only focuses on the list price.
