1. What are the tiny blood vessels that transport blood from arteries to veins within the body?

• A. Arterioles
• B. Capillaries
• C. Venules
• D. Veins

Correct answer: B

Rationale: The correct answer is B: Capillaries. Capillaries are the smallest blood vessels that connect arterioles (small arteries) with venules (small veins). They enable the exchange of oxygen, nutrients, and waste products between the blood and tissues. Arterioles are small arteries that carry blood away from the heart, while venules are small veins that carry blood towards the heart. Veins are larger blood vessels that transport blood back to the heart. Therefore, capillaries specifically serve as the vessels responsible for the exchange of substances between the blood and body tissues.

2. 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.

3. Identify the type of error in the sentence, 'They went to the store, bought groceries, then went home.'

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The given sentence combines multiple independent clauses without appropriate punctuation or conjunctions, creating a run-on sentence. A run-on sentence occurs when two or more independent clauses are joined without the necessary punctuation or coordination. In this case, the sentence lacks the proper conjunction or punctuation between 'store' and 'bought,' resulting in a run-on sentence. Choice B, 'Comma splice,' is incorrect because a comma splice involves joining two independent clauses with just a comma, which is not the case in the given sentence. Choice C, 'Dangling modifier,' is incorrect as there are no misplaced modifiers in the sentence. Choice D, 'Subject-verb agreement,' is also incorrect as the error in the sentence does not involve subject-verb agreement but rather the incorrect combination of independent clauses.

4. A 'competitive salary' is one that is

• A. Much less than salaries offered for comparable jobs
• B. Much greater than salaries offered for comparable jobs
• C. Similar to the average salary offered for comparable jobs
• D. Impossible to compare to the salaries offered for comparable jobs

Correct answer: C

Rationale: A competitive salary is one that is similar to the average salary offered for comparable jobs. In the context of the job advertisement provided, a competitive salary is typically in line with what other employers are paying for similar positions to attract and retain the best talent in the industry. Choice A is incorrect because a competitive salary is not 'much less' than salaries offered for comparable jobs; it aims to be competitive. Choice B is incorrect as a competitive salary is not 'much greater' than salaries offered for comparable jobs; it aims to be fair and competitive. Choice D is incorrect as a competitive salary is not 'impossible to compare to' the salaries offered for comparable jobs; it is meant to be competitive and aligned with industry standards.

5. What is the median of the data set below: 5, -3, 10, -2, 0?

• A. 10
• B. 0
• C. 5
• D. 2

Correct answer: B

Rationale: To find the median, we first need to arrange the data set in ascending order: -3, -2, 0, 5, 10. The median is the middle value in the ordered set. As there are 5 numbers, the middle value is the third number, which is 0. Therefore, the correct answer is 0. Choice A (10) and Choice D (2) are not correct because they are not the middle values once the data set is ordered. Choice C (5) is also incorrect as it is not the middle value in the ordered data set.
