1. The words 'aerobics' and 'aeronautics' both have the prefix 'aero' in common. What does 'aero' mean?

• A. Light
• B. Speed
• C. Distance
• D. Air

Correct answer: D

Rationale: The prefix 'aero' is derived from the Greek word 'aēr,' which means air. In words like 'aerobics' and 'aeronautics,' the prefix 'aero' refers to air-related activities or concepts. Therefore, 'air' is the correct meaning of the prefix 'aero.' Choices A, B, and C are incorrect. 'Light' does not relate to the prefix 'aero,' 'speed' and 'distance' are not associated with the concept of air as in 'aero,' making them incorrect answers.

2. What type of reaction is represented by the following equation: 2C₆H₁₄ + 19O₂ → 12CO + 14H₂O?

• A. Substitution reaction
• B. Acid-base reaction
• C. Enzyme reaction
• D. Combustion reaction

Correct answer: D

Rationale: The given chemical equation represents a combustion reaction. Combustion reactions involve the burning of a hydrocarbon (C₆H₁₄) in the presence of oxygen (O₂) to produce carbon monoxide (CO) and water (H₂O). Combustion reactions typically release heat and light energy. In this case, the reactants are a hydrocarbon and oxygen, resulting in the formation of carbon monoxide and water. Choices A, B, and C are incorrect because the reaction does not involve substitution, acid-base reactions, or enzyme catalysis. Combustion reactions are characterized by the rapid combination of a substance with oxygen, leading to the production of heat and light energy.

3. What kind of error does the following sentence contain? Forgetting that he was supposed to meet his girlfriend for dinner, Anita was mad when Fred showed up late.

• A. Parallelism
• B. Run-on sentence
• C. Misplaced modifier
• D. Subject-verb agreement

Correct answer: C

Rationale: The correct answer is C, misplaced modifier. In this sentence, the modifier 'Forgetting that he was supposed to meet his girlfriend for dinner' is placed incorrectly, suggesting that Anita forgot, when it was actually Fred who forgot. The modifier should be positioned closer to 'Fred' to clarify the intended meaning. Choices A, B, and D are incorrect. Parallelism is not an issue in this sentence, it is not a run-on sentence as it is grammatically correct, and there is no subject-verb agreement error present.

4. Futuristic Furniture gave the man two choices: pay the entire amount in one payment with cash, or pay $1000 as a down payment and $120 per month for two full years in the financing plan. If the man chooses the financing plan, how much more would he pay?

• A. $1480 more
• B. $1280 more
• C. $1600 more
• D. $2480 more

Correct answer: B

Rationale: If the man chooses the financing plan, he pays $1000 as a down payment initially. Over the two-year period, he will be paying $120 per month for a total of 24 months, which amounts to $120 x 24 = $2880. Therefore, the total amount he pays for the furniture through the financing plan is $1000 (down payment) + $2880 (monthly payments) = $3880. Comparing this total with the entire amount paid in one payment with cash would be $3880 - $3000 = $880 more. So, the man would pay $880 more if he chooses the financing plan. Therefore, the correct answer is $1280 more, not $1480, $1600, or $2480. These amounts do not accurately represent the additional cost incurred by choosing the financing plan.

5. Which locations in the digestive system are sites of chemical digestion? I. Mouth II. Stomach III. Small Intestine

• A. II only
• B. III only
• C. II and III only
• D. I, II, and III

Correct answer: D

Rationale: Chemical digestion occurs in all three locations in the digestive system - the mouth, stomach, and small intestine. Enzymes in the saliva break down carbohydrates in the mouth, gastric juices in the stomach help break down proteins, and enzymes in the small intestine further break down macronutrients like carbohydrates, proteins, and fats. The mouth initiates the digestion of carbohydrates, the stomach digests proteins, and the small intestine continues the breakdown of carbohydrates, proteins, and fats. Choice A is incorrect because chemical digestion does occur in the mouth. Choice B is incorrect as both the stomach and small intestine are sites of chemical digestion. Choice C is incorrect as the mouth is also a location of chemical digestion, not just the stomach and small intestine.
