1. Which of the following describes a proportional relationship?

• A. Johnathan opens a savings account with an initial deposit of $150 and deposits $125 per month
• B. Bruce pays his employees $12 per hour worked during the month of December, as well as a $250 bonus
• C. Alvin pays $28 per month for his phone service plus $0.07 for each long-distance minute used
• D. Kevin drives 65 miles per hour

Correct answer: A

Rationale: A proportional relationship is one in which two quantities vary directly with each other. In choice A, the amount deposited per month is directly proportional to the initial deposit. The relationship can be represented as y = 125x + 150, where x is the number of months and y is the total amount in the account. Choices B and C involve additional fixed amounts or variable costs that do not maintain a constant ratio, making them non-proportional relationships. Choice D refers to a constant speed of driving, which is not a proportional relationship as it does not involve varying quantities that change in direct proportion.

2. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective 'enthusiastic'?

• A. enthusiastic
• B. enthusiastically
• C. enthusiasm
• D. enthuse

Correct answer: C

Rationale: The correct answer is 'C: enthusiasm.' The noun form of the adjective 'enthusiastic' is 'enthusiasm.' Nouns are often formed from adjectives by changing the suffix; in this case, '-ic' in 'enthusiastic' changes to '-m' in 'enthusiasm.' 'Entusiastic' is an adjective and does not function as a noun. 'Enthusiastically' is an adverb as it describes how something is done, not a noun. 'Enthuse' is a verb and does not represent the noun form of 'enthusiastic.' It is important to understand the relationships between different parts of speech when analyzing word forms.

3. The Becquerel (Bq) is the designated unit for quantifying:

• A. Electron volt (eV) measurements of energy
• B. Radioactivity
• C. Electric charge (Coulombs)
• D. Force (Newtons)

Correct answer: B

Rationale: The Becquerel (Bq) is the unit used to measure radioactivity, specifically the activity of a quantity of radioactive material. It represents the number of radioactive disintegrations or transformations per unit of time. Choice A, electron volt (eV), is a unit of energy, not radioactivity. Choice C, electric charge (Coulombs), is measured in Coulombs, not Becquerels. Choice D, force (Newtons), is a unit of force, not radioactivity. Therefore, the correct answer is B.

4. Which element is used in semiconductors like computer chips and solar panels?

• A. Germanium
• B. Silicon
• C. Gallium
• D. Arsenic

Correct answer: B

Rationale: Silicon is the correct answer. Silicon is widely used in semiconductors for electronic applications because of its unique properties that allow it to be manipulated to conduct or not conduct electricity effectively. Germanium is also used in semiconductors but to a lesser extent compared to silicon. Gallium and arsenic are not as commonly used in semiconductors like computer chips and solar panels, making them incorrect choices for this question.

5. Which of the following best provides detailed support for the claim that 'seatbelts save lives'?

• A. A government website containing driving accident information
• B. A blog developed by one of the largest car companies in the world
• C. An encyclopedia entry on the seatbelt and its development
• D. A social media post from a famous race car driver

Correct answer: A

Rationale: The correct answer is A. Government websites usually contain reliable and detailed statistics supporting the effectiveness of seatbelts. Choice B, a blog from a car company, may have biased information to promote their products. Choice C, an encyclopedia entry, may not necessarily have the most up-to-date or detailed information on the topic. Choice D, a social media post from a race car driver, lacks the credibility and detailed information that a government website can provide.
