1. Reread the following sentence from the passage: 'Don't hit me with arguments about greater freedom for workers.' Which of the following would be a more formal way to rewrite the sentence?

• A. I disagree with the argument about contract workers having greater freedom.
• B. Stop telling me that freelancers have more freedom!
• C. Is there actually freedom for workers?
• D. I've already heard.

Correct answer: A

Rationale: Choice A, 'I disagree with the argument about contract workers having greater freedom,' is the correct answer. This sentence rephrases the original statement in a more formal and respectful tone, which is suitable for formal writing. Choice B is too direct and lacks formality. Choice C does not address the argument directly and poses a question instead of providing a formal statement. Choice D is dismissive and does not offer a formal rewrite of the original sentence.

2. Which of the following is NOT an effective brainstorming strategy?

• A. Making a list of possible topics/subtopics
• B. Daydreaming until inspiration strikes
• C. Freewriting, then reading over what you wrote
• D. Asking yourself who, what, where, when, why, and how

Correct answer: B

Rationale: Daydreaming is a passive process and may not always lead to concrete ideas. Effective brainstorming involves actively generating ideas through structured methods. Making a list of topics/subtopics helps organize thoughts, freewriting encourages continuous idea flow, and asking specific questions prompts deeper thinking and idea generation. Daydreaming, on the other hand, lacks structure and may not consistently yield productive results in a brainstorming session.

3. What information can be obtained from the mass number of an element?

• A. The number of protons in the nucleus
• B. The total number of protons and neutrons
• C. The number of electrons in the valence shell
• D. The element's chemical reactivity

Correct answer: B

Rationale: The mass number of an element represents the total number of protons and neutrons in the nucleus. This information is crucial for determining the atomic mass of the element and understanding its stability and isotopes. The number of protons in the nucleus (option A) is represented by the atomic number, not the mass number. The number of electrons in the valence shell (option C) is related to the element's position in the periodic table and its chemical properties, but it is not directly determined by the mass number. The element's chemical reactivity (option D) is influenced by the number and arrangement of electrons in the atom's energy levels, not by the mass number.

4. What is the probability of consecutively pulling two more orange blocks, without replacement, from a bag containing 3 orange blocks, 5 green blocks, and 4 purple blocks?

• A. 3/12
• B. 3/55
• C. 2/10
• D. 1/3

Correct answer: B

Rationale: To calculate the probability of consecutively pulling two more orange blocks without replacement, we first determine the probability of pulling an orange block on the first draw, which is 3/12 (3 orange blocks out of 12 total blocks). After removing one orange block, there are only 11 blocks left, so the probability of pulling another orange block on the second draw is 2/11. To find the combined probability, we multiply the probabilities together: (3/12) * (2/11) = 6/132 = 3/55. Therefore, the correct answer is B. Choice A (3/12) incorrectly simplifies the probability before calculating the second draw. Choice C (2/10) does not consider the specific number of orange blocks in the bag. Choice D (1/3) does not account for the reduced number of blocks after the first draw.

5. What is the balanced chemical equation for the reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH)?

• A. H2SO4 + KOH → K2SO4 + H2O
• B. 2H2SO4 + 2KOH → 2K2SO4 + 2H2O
• C. H2SO4 + 2KOH → K2SO4 + 2H2O
• D. H2SO4 + 2KOH → K2SO4 + H2O

Correct answer: C

Rationale: When sulfuric acid (H2SO4) reacts with potassium hydroxide (KOH), it forms potassium sulfate (K2SO4) and water (H2O). To balance the equation, 2 KOH molecules are required to react with 1 H2SO4 molecule, resulting in 1 K2SO4 molecule and 2 H2O molecules. Therefore, the balanced chemical equation is H2SO4 + 2KOH → K2SO4 + 2H2O, which corresponds to option C. Choice A is incorrect because it does not account for the correct stoichiometry between the reactants and products. Choice B incorrectly doubles all the molecules in the reaction, leading to an unbalanced equation. Choice D incorrectly balances the equation with 1 KOH molecule instead of the required 2 KOH molecules, making it unbalanced. Thus, option C is the correct balanced chemical equation for the reaction between sulfuric acid and potassium hydroxide.
