1. Which element would you expect to be least reactive?

• A. Li
• B. Cr
• C. Nd
• D. Xe

Correct answer: D

Rationale: Xenon (Xe) is a noble gas located in Group 18 of the periodic table. Noble gases are known for their stable and unreactive nature due to having a full outer shell of electrons. Therefore, xenon would be expected to be the least reactive among the given elements. Choice A (Li) is a metal in Group 1 of the periodic table, which tends to be reactive, especially with water. Choice B (Cr) is a transition metal known for its reactivity in some forms. Choice C (Nd) is a rare earth element, which can exhibit varying reactivity depending on the compound or environment.

2. Identify the dependent clause in this sentence: The mother dog left her bed as soon as the puppies were asleep.

• A. As soon as the puppies were asleep
• B. Left her bed as soon as
• C. The puppies were asleep
• D. The mother dog left her bed

Correct answer: A

Rationale: The correct answer is A: 'As soon as the puppies were asleep' is the dependent clause in the sentence. It functions as an adverbial clause, indicating a time relationship with the action of the mother dog leaving her bed. Dependent clauses rely on independent clauses to form complete sentences and cannot stand alone. Choice B is incorrect because it separates the dependent clause. Choice C is incorrect as it is a noun phrase. Choice D is incorrect as it is an independent clause.

3. What does 'lethargic' mean?

• A. Active
• B. Difficult to arouse
• C. Energized
• D. Wide awake

Correct answer: B

Rationale: Lethargic refers to a state of sluggishness or drowsiness, making it difficult for a person to become alert or aroused. This term is the opposite of being active, energized, or wide awake. Choice A is incorrect as 'lethargic' is the opposite of 'active.' Choice C is incorrect as 'lethargic' implies a lack of energy. Choice D is incorrect as 'lethargic' signifies drowsiness, the opposite of being 'wide awake.' The correct answer is B.

4. Which is a byproduct of fermentation in muscle cells?

• A. Ethanol
• B. Pyruvic acid
• C. Lactic acid
• D. Oxygen

Correct answer: C

Rationale: Lactic acid is a byproduct of fermentation in muscle cells. During intense exercise or when oxygen is limited, muscle cells use anaerobic respiration to generate energy. This process breaks down glucose into lactic acid, which can cause muscle fatigue and soreness. Choice A, Ethanol, is not produced in muscle cells during fermentation. Choice B, Pyruvic acid, is an intermediate product in glucose metabolism but is not a byproduct of fermentation in muscle cells. Choice D, Oxygen, is not a byproduct of fermentation but a reactant in aerobic respiration.

5. If the outside temperature on a sunny day is 82 degrees on the Fahrenheit scale, what is the approximate temperature on the Celsius scale?

• A. 18°C
• B. 24°C
• C. 28°C
• D. 50°C

Correct answer: C

Rationale: To convert Fahrenheit to Celsius, you can use the formula:
