1. Which conjunction best joins the following sentence: 'She loves animals, ____ she volunteers at the shelter.'

• A. because
• B. therefore
• C. so
• D. and

Correct answer: D

Rationale: The correct answer is 'and.' 'And' is the most appropriate conjunction here as it simply adds information about her love for animals without implying cause or effect. It connects two independent clauses in a neutral way, indicating that she loves animals and also volunteers at the shelter. The other choices, 'because,' 'therefore,' and 'so,' suggest a cause-and-effect relationship between loving animals and volunteering at the shelter, which is not the intended meaning in this context.

2. What is the law that states energy can neither be created nor destroyed?

• A. Law of Conservation of Matter
• B. Law of Conservation of Energy
• C. Law of Universal Gravitation
• D. Law of Inertia

Correct answer: B

Rationale: The correct answer is the Law of Conservation of Energy. This law states that energy cannot be created or destroyed, only transformed from one form to another. The Law of Conservation of Matter (Choice A) is related to mass and the preservation of mass in a closed system, not energy. The Law of Universal Gravitation (Choice C) describes the force of attraction between objects with mass. The Law of Inertia (Choice D) states that an object will remain at rest or in uniform motion unless acted upon by an external force.

3. Solve for x: 2x + 4 = x - 6

• A. x = -12
• B. x = 10
• C. x = -16
• D. x = -10

Correct answer: D

Rationale: To solve the equation 2x + 4 = x - 6, first, subtract x from both sides to get x + 4 = -6. Then, subtract 4 from both sides to isolate x, resulting in x = -10. Therefore, the correct answer is x = -10. Choice A is incorrect as it does not follow the correct steps of solving the equation. Choice B is incorrect as it is the result of combining x terms incorrectly. Choice C is incorrect as it is not the correct result of solving the equation step by step.

4. According to the periodic table, which of the following elements is the least reactive?

• A. Fluorine
• B. Silicon
• C. Neon
• D. Gallium

Correct answer: C

Rationale: Neon is the least reactive among the given elements because it belongs to the noble gases group in the periodic table. Noble gases have a full valence shell of electrons, making them highly stable and least likely to react with other elements. Fluorine is the most reactive non-metal due to its high electronegativity. Silicon is a metalloid with moderate reactivity, falling between metals and nonmetals. Gallium is a metal with higher reactivity compared to Neon, but it is not as reactive as Fluorine.

5. If a product's original price is $80 and it is discounted by 20%, what is the final price?

• A. 64
• B. 60
• C. 70
• D. 66

Correct answer: A

Rationale: To find the discounted price, you first calculate 20% of the original price: 20% of $80 is $16. Subtracting this discount amount from the original price gives the final price: $80 - $16 = $64. Therefore, the final price after a 20% discount on a product originally priced at $80 is $64. Choice B, $60, is incorrect because it does not account for the correct discount amount. Choice C, $70, is incorrect as it does not reflect the reduction due to the 20% discount. Choice D, $66, is incorrect as it miscalculates the discounted price.
