1. Based on the passage, which conclusion can be drawn about the author?

• A. They are overly emotional and...
• B. They would rather be at a concert
• C. They go to the theater as often as possible
• D. They enjoy the decor of most theaters

Correct answer: C

Rationale: The correct answer is C. The passage does not mention anything about the author's emotional state or preference for concerts. However, it does discuss cicadas and their emergence, life cycle, and behavior. Therefore, the reader can conclude that the author is likely interested in cicadas and their natural history, indicating that they go to the theater as often as possible. Choice A is incorrect because there is no evidence regarding the author being overly emotional. Choice B is incorrect as there is no mention of the author's preference for concerts. Choice D is incorrect as the passage does not provide any information about the author enjoying theater decor.

2. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

• A. table
• B. leg
• C. ouch
• D. stubbed

Correct answer: C

Rationale: The correct answer is C, 'ouch'. Interjections are words or phrases used to express strong emotions or sudden feelings. In this sentence, 'ouch' expresses pain, making it an interjection in the given context. Choices A, B, and D are incorrect as they do not represent interjections. 'Table' and 'leg' are nouns, while 'stubbed' is a past tense verb, none of which serve as interjections in this sentence.

3. What is 0.004 expressed as a ratio?

• A. 1:250
• B. 4:20
• C. 2:40
• D. 9:20

Correct answer: A

Rationale: The decimal 0.004 can be represented as a ratio of 4/1000, which simplifies to 1/250, making the ratio 1:250. The correct answer is A. Choices B, C, and D are incorrect because they do not reflect the correct conversion of 0.004 into a simplified ratio. Choice B simplifies to 1:5, Choice C simplifies to 1:20, and Choice D simplifies to 9:20, none of which accurately represent the ratio of 0.004.

4. How many grams are in 1 kilogram?

• A. 10 grams
• B. 100 grams
• C. 1,000 grams
• D. 10,000 grams

Correct answer: C

Rationale: The correct answer is C: 1,000 grams. The metric system follows a logical conversion where 1 kilogram is equal to 1,000 grams. This conversion is a fundamental concept in understanding units of measurement. Choices A, B, and D are incorrect because they do not accurately reflect the conversion between kilograms and grams. Option A (10 grams) is incorrect as it represents 1/100th of the correct conversion. Option B (100 grams) is also incorrect as it represents 1/10th of the correct conversion. Option D (10,000 grams) is significantly higher than the actual conversion, making it incorrect. Understanding these basic unit conversions is essential for various fields where precise measurements are necessary.

5. What is the feedback mechanism in the endocrine system that helps maintain hormone balance?

• A. Positive feedback, where a hormone stimulates its own release
• B. Negative feedback, where a hormone suppresses its own release
• C. Cascade effect, where one hormone triggers the release of another
• D. Dual hormone system, where two hormones work together

Correct answer: B

Rationale: In the endocrine system, negative feedback is the mechanism by which hormone levels are regulated. When hormone levels reach a certain threshold, they signal the body to stop producing more of that hormone, thus maintaining a balance. Negative feedback (option B) is the correct answer as it helps in preventing overproduction of hormones by suppressing their own release. Positive feedback (option A) would lead to an excessive production of hormones, disrupting the balance. The cascade effect (option C) involves one hormone triggering the release of another but does not directly regulate hormone levels. The dual hormone system (option D) refers to two hormones working together but does not specifically address the feedback mechanism for maintaining hormone balance.
