1. The largest level of ecological organization is a:

• A. Population
• B. Community
• C. Ecosystem
• D. Biome

Correct answer: D

Rationale: A) Population: A population consists of individuals of the same species living in the same area. It is a smaller level of ecological organization compared to a biome. B) Community: A community consists of populations of different species living and interacting in the same area. It is a larger level of organization than a population but smaller than an ecosystem or biome. C) Ecosystem: An ecosystem includes all living organisms (biotic factors) and their physical environment (abiotic factors) interacting in a particular area. It is a larger level of organization than a community but smaller than a biome. D) Biome: The correct answer is D - Biome. A biome is the largest level of ecological organization and encompasses a large geographic area characterized by a specific climate, vegetation, and animal life. Biomes can be found on multiple continents and are defined by similar abiotic and biotic factors. Therefore, it is the largest level of ecological organization among the options provided, making it the correct answer.

2. Which of the following describes a real-world situation that could be modeled by?

• A. Courtney charges a $12 fee plus $2 per hour to babysit. Kendra charges a $10 fee plus $5 per hour. Write an equation to find the number of hours for which the two charges are equal.
• B. Courtney charges a $2 fee plus $12 per hour to babysit. Kendra charges a $5 fee plus $10 per hour. Write an equation to find the number of hours for which the two charges are equal.
• C. Courtney charges a $12 fee plus $2 to babysit. Kendra charges a $10 fee plus $5 to babysit. Write an equation to find the number of hours for which the two charges are equal.
• D. Courtney charges $10 plus $2 per hour to babysit. Kendra charges $12 plus $5 per hour. Write an equation to find the number of hours for which the two charges are equal.

Correct answer: A

Rationale: In the given situation, Courtney charges a $12 fee plus $2 per hour to babysit, represented by the equation: 12 + 2h where h is the number of hours. Kendra charges a $10 fee plus $5 per hour, represented by the equation: 10 + 5h. To find the number of hours for which the two charges are equal, we set the two equations equal to each other: 12 + 2h = 10 + 5h. Solving for h gives h = 2. This means that the charges are equal after 2 hours of babysitting. Choice B is incorrect because the fee and hourly rates for Courtney and Kendra are reversed, leading to an incorrect equation. Choices C and D are incorrect as they do not accurately represent the given scenario of fees and hourly rates for babysitting by Courtney and Kendra.

3. Which of the following verb forms correctly completes the sentence? His charismatic personality, organizational abilities, sheer determination, and rhetorical skills enable him to quickly rise through the chapter's ranks.

• A. NO CHANGE
• B. are enabling him to quickly rise
• C. enabled him to quickly rise
• D. will enable him to quickly rise

Correct answer: C

Rationale: Option C, 'enabled him to quickly rise,' is the correct choice. The sentence is referring to a past action, so the verb should be in the past tense. 'Enabled' is the correct past tense form of 'enable' in this context. Choice A ('NO CHANGE') is incorrect because it does not match the past tense required by the sentence. Option B ('are enabling him to quickly rise') is incorrect as it uses the present continuous tense, which is not suitable for the past action described. Choice D ('will enable him to quickly rise') is incorrect as it implies a future action, which is not consistent with the context of the sentence.

4. In the words proactive, progress, and projecting, pro- is a(n) _______ that means _______.

• A. suffix; good, on top of, or over
• B. prefix; before, forward, or front
• C. affix; after, behind, or in back of
• D. prefix; against, under, or below

Correct answer: B

Rationale: In the words proactive, progress, and projecting, 'pro-' is a prefix meaning 'before, forward, or front.' This prefix denotes something happening before or moving forward, as seen in 'progress' and 'projecting,' where it signifies moving ahead or progressing. Therefore, the correct answer is B. Choices A, C, and D are incorrect because 'pro-' is not a suffix, affix, or prefix that means 'good, on top of, or over,' 'after, behind, or in back of,' or 'against, under, or below' respectively. The key is to recognize the meaning of the prefix 'pro-' in the given words and associate it with concepts related to being before or moving forward.

5. Which word in the following sentence is a homophone of 'I'll'?

• A. Me
• B. Aisle
• C. I'm
• D. Ill

Correct answer: B

Rationale: 'Aisle' is the correct answer. A homophone is a word that is pronounced the same as another word but has a different meaning or spelling. In this sentence, 'I'll' is a homophone of 'aisle' as they sound the same but have distinct definitions and spellings. Choices A, C, and D do not fit the criteria of being homophones of 'I'll'.
