1. Jessica buys 10 cans of paint. Red paint costs $1 per can, and blue paint costs $2 per can. In total, she spends $16. How many red cans did she buy?

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: C

Rationale: Let r be the number of red cans and b be the number of blue cans. The total cans equation is r + b = 10. The total cost equation is r + 2b = 16. By solving these equations simultaneously, we find r = 4. Therefore, Jessica bought 4 red cans. Choice A, 2 red cans, is incorrect because it does not satisfy the total cans or total cost condition. Choices B and D are also incorrect as they do not fulfill both conditions simultaneously.

2. The brain is part of which system?

• A. Integumentary system
• B. Nervous system
• C. Endocrine system
• D. Respiratory system

Correct answer: B

Rationale: The brain is a crucial organ that serves as the command center of the body, making it a key component of the nervous system. It processes sensory information, coordinates movements, and regulates various bodily functions. Therefore, the brain is correctly categorized as part of the nervous system. Choices A, C, and D are incorrect because the integumentary system pertains to the skin, the endocrine system involves hormone regulation, and the respiratory system is responsible for breathing. These systems do not encompass the brain's functions or structure.

3. Ibexes are wild mountain goats that live in the Alps and the mountains of Asia. They climb very steep slopes. They are sure-footed and can easily leap from rock to rock. In winter, they replace their summer coat with thicker hair and a wooly undercoat.

• A. Ibexes are wild mountain goats that are very agile.
• B. Ibexes are found in lowlands and highlands.
• C. Ibexes like to climb steep slopes in the mountains.
• D. Ibexes have adapted to life in the mountains.

Correct answer: D

Rationale: The correct answer is 'Ibexes have adapted to life in the mountains' because it serves as a concluding sentence that summarizes the content of the paragraph. This statement encapsulates the information provided about ibexes living in the Alps and Asian mountains, climbing steep slopes, being sure-footed, and changing their coats in winter. Choice A is incorrect because the text does not specifically mention their agility. Choice B is incorrect as the text only mentions the Alps and Asian mountains, not lowlands. Choice C is also incorrect as the text mentions ibexes climbing steep slopes, not just liking to do so.

4. Select the correct definition of the underlined word having multiple meanings in the sentence: 'Natalie’s fingers were calloused after practicing her bass.'

• A. Kind of fish
• B. Low and deep sound
• C. Lowest male singing voice
• D. A guitar with four strings that makes low sounds

Correct answer: D

Rationale: In this sentence, 'bass' refers to a guitar with four strings that makes low sounds. The context of Natalie practicing suggests that it is referring to a musical instrument, specifically the bass guitar, rather than a fish, sound, or voice. Therefore, the correct answer is D. Choice A, 'Kind of fish,' is incorrect as the sentence context does not relate to fish. Choice B, 'Low and deep sound,' is incorrect because the sentence refers to practicing an instrument, not just a sound. Choice C, 'Lowest male singing voice,' is also incorrect as the sentence context is not related to singing but to playing an instrument.

5. Which of the following is an example of a tissue?

• A. chloroplasts
• B. liver
• C. mammal
• D. hamstring

Correct answer: B

Rationale: The correct answer is 'B: liver.' The liver is an example of a tissue. Tissues are groups of cells that work together to perform specific functions in the body. The liver is made up of different types of cells that work together to carry out various essential functions, such as detoxification, metabolism, and storage of nutrients. Option A (chloroplasts) refers to organelles, not tissues. Option D (hamstring) is a muscle, not a tissue. Option C (mammal) represents a higher level of organization than tissues, as it refers to a classification of organisms, not a specific tissue type.
