1. The phone bill is calculated each month using the equation C = 50 + 75D. The cost of the phone bill per month is represented by C, and D represents the gigabytes of data used that month. What is the value and interpretation of the slope of this equation?

• A. 75 dollars per gigabyte
• B. 75 gigabytes per day
• C. 50 dollars per day
• D. 50 dollars per gigabyte

Correct answer: A

Rationale: The slope of the equation C = 50 + 75D is 75. This means that for each additional gigabyte used (represented by D), the cost (represented by C) increases by 75 dollars. Therefore, the correct interpretation of the slope is that it is 75 dollars per gigabyte. Choice B, 75 gigabytes per day, is incorrect as the slope does not represent the rate of data usage per day. Choice C, 50 dollars per day, is incorrect as it does not reflect the relationship between gigabytes used and the cost. Choice D, 50 dollars per gigabyte, is incorrect as it does not match the slope value of 75 in the equation.

2. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

• A. Lungs
• B. Intestines
• C. Kidneys
• D. Skin

Correct answer: B

Rationale: Chyle, a milky white fluid, is formed in the small intestine during digestion. It is composed of lymph and emulsified fats. Lymphatic vessels in the intestines, specifically lacteals, transport chyle from the intestines to the bloodstream for the distribution of nutrients throughout the body. The transport of chyle from the lungs, kidneys, or skin is not correct as these organs are not primarily involved in the production or transportation of chyle.

3. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: B

Rationale: The correct answer is B: Frequency increases. Frequency and wavelength are inversely proportional in a wave with a constant speed. When the wavelength decreases while the speed remains constant, the frequency must increase to maintain the constant speed of the wave. This relationship is governed by the equation: speed = frequency x wavelength. Choice A is incorrect as frequency increases when wavelength decreases. Choice C is incorrect as the frequency changes in this scenario. Choice D is incorrect as the frequency does not become zero but increases when the wavelength decreases.

4. To which section of the library should Jorgen go to learn more about the letters of the Greek alphabet and the meaning of the word 'beta'?

• A. 200
• B. 400
• C. 700
• D. 900

Correct answer: B

Rationale: Jorgen should go to section 400 in the library to learn more about the letters of the Greek alphabet and the meaning of the word 'beta.' Section 400 is dedicated to languages, making it the most suitable place to find information on alphabets. Choices A, C, and D are incorrect because Section 200 is about religion, Section 700 is about arts and recreation, and Section 900 is about history, geography, and biography, which are not relevant to Jorgen's search for information on the Greek alphabet.

5. Identify the participial phrase in the following sentence: 'Running through the park, she spotted a squirrel.'

• A. Running
• B. Through the park
• C. She spotted
• D. A squirrel

Correct answer: B

Rationale: The correct answer is 'B: Through the park.' A participial phrase acts as an adjective and is formed from a verb. In this sentence, 'Running through the park' describes 'she' and functions as an adjective modifying the subject. Choice A 'Running' is incorrect because it is just the present participle without additional context to form a phrase. Choice C 'She spotted' is incorrect as it is a subject and a verb, not a participial phrase. Choice D 'A squirrel' is incorrect as it is a noun phrase, not a participial phrase.
