1. Which of the following are examples of positive correlation?

• A. As rainfall increases, plant stem length decreases.
• B. As rainfall increases, roots show longer length.
• C. When plotting a comparison of rainfall to plant length, the line trends to the lower right.
• D. When plotting a comparison of rainfall to plant length, the line trends to the upper right.

Correct answer: D

Rationale: The correct answer is D. Positive correlation indicates that as one variable increases, the other variable also increases. In this case, when plotting a comparison of rainfall to plant length, if the line trends to the upper right, it shows a positive correlation where as rainfall increases, plant length also increases. Choices A, B, and C show either no correlation or negative correlation, as they describe scenarios where the variables move in different or opposite directions.

2. What is bile, where is it produced, where is it stored, and what is its function?

• A. Produced in the pancreas, stored in the liver, aids in digestion
• B. Produced in the liver, stored in the gallbladder, aids in fat digestion
• C. Produced in the stomach, stored in the pancreas, neutralizes acid
• D. Produced in the gallbladder, stored in the liver, breaks down proteins

Correct answer: B

Rationale: Bile is a digestive fluid produced in the liver, stored in the gallbladder, and it aids in the digestion of fats by emulsifying them. Emulsification helps to break down fats into smaller particles, facilitating their digestion by enzymes in the small intestine. Choice A is incorrect because bile is not produced in the pancreas, and it is not stored in the liver. Choice C is incorrect as bile is not produced in the stomach, and it does not neutralize acid. Choice D is also incorrect as bile is not produced in the gallbladder, and its primary function is not to break down proteins.

3. Which of the following would be a useful source of information to determine the validity of the argument presented in the passage?

• A. A survey of high school students' preferences regarding foreign language requirements.
• B. A comparison of the correlation between a second language introduced at home and subsequent college acceptance rates.
• C. A survey asking parents to select the foreign language they would like their children to study in high school.
• D. A comparison of the correlation between high school students' study of a foreign language and subsequent college acceptance rates.

Correct answer: D

Rationale: The passage emphasizes the importance of studying a foreign language in high school for future success, including college acceptance rates and job market demand. To evaluate the argument's validity, it is crucial to examine the direct impact of studying a foreign language on college acceptance rates. Choice D is the correct answer because it directly addresses this aspect by comparing the correlation between high school students' study of a foreign language and subsequent college acceptance rates. This comparison would provide concrete evidence supporting or refuting the argument presented in the passage. Choices A, B, and C, though related to language education, do not directly assess the specific relationship between studying a foreign language in high school and college acceptance rates, making them less relevant for evaluating the argument's validity.

4. Identify the interrogative sentence in the following options:

• A. The delicious pie disappeared quickly.
• B. What is your favorite color?
• C. Please open the window.
• D. He ran as fast as he could.

Correct answer: B

Rationale: An interrogative sentence is a type of sentence that asks a question. In this case, choice B 'What is your favorite color?' is an interrogative sentence because it is asking a question and ends with a question mark. Choices A, C, and D are not interrogative sentences as they do not pose a question to elicit a response. Choice A is a declarative sentence, choice C is an imperative sentence, and choice D is also a declarative sentence.

5. Which of the following is a constant?

• A. The number of protons in an oxygen atom
• B. The temperature at which iron ore will melt
• C. The human population size
• D. The time the sun rises each day

Correct answer: A

Rationale: The number of protons in an oxygen atom is a constant. This value is determined by the atomic number of the element and does not change regardless of the isotope of oxygen. The number of protons defines the element and remains consistent under normal conditions. Choices B, C, and D are not constants. The temperature at which iron ore will melt can vary depending on factors like pressure, the human population size is constantly changing, and the time the sun rises each day varies with the seasons and location.
