1. Which organ is responsible for filtering blood and removing waste products?

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is the kidneys. The kidneys filter blood and remove waste products through the formation of urine. The liver primarily functions in detoxification and metabolism. The spleen is involved in blood filtering and immune function. The pancreas produces digestive enzymes and insulin, not involved in filtering blood.

2. Simplify the following expression: 3 (1/6) - 1 (5/6)

• A. 2 (1/3)
• B. 1 (1/3)
• C. 2 (1/9)
• D. 5/6

Correct answer: B

Rationale: To simplify: First, subtract the whole numbers: 3 - 1 = 2. Then, subtract the fractions: (1/6) - (5/6) = - (4/6) = - (2/3). Now, subtract (2 - 2/3) = 1 (1/3).

3. The number of protons in an atom is determined by its:

• A. Atomic mass
• B. Electron configuration
• C. Chemical properties
• D. Atomic number

Correct answer: D

Rationale: The number of protons in an atom is determined by its atomic number. The atomic number represents the number of protons in the nucleus of an atom, which also determines the element's identity. Therefore, the correct answer is (D) Atomic number. Choices (A) Atomic mass, (B) Electron configuration, and (C) Chemical properties are not directly related to the number of protons in an atom. Atomic mass is the total mass of protons, neutrons, and electrons in an atom. Electron configuration refers to the arrangement of electrons in an atom's energy levels, and chemical properties are determined by the arrangement of electrons in the outermost energy level.

4. Select the subject with which the underlined verb must agree: 'Everyone I know has the day off, but my boss wants me to work.'

• A. Everyone
• B. I
• C. day
• D. boss

Correct answer: A

Rationale: The correct answer is 'A: Everyone.' In the sentence, the verb 'has' must agree with the singular subject 'Everyone.' 'I,' 'day,' and 'boss' are not the subjects that the verb 'has' must agree with. 'I' is the object pronoun, 'day' is the object of the preposition 'off,' and 'boss' is part of the second clause and not the subject that governs the verb agreement in the first clause.

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.
