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

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

Correct answer: D

Rationale: The slope of the equation y = 50x is 50, which means that for each additional gigabyte of data used, the cost increases by 50 dollars. Therefore, the interpretation of the slope is that it represents the cost per gigabyte, making '50 dollars per gigabyte' the correct answer. Choices A, B, and C are incorrect because they do not reflect the relationship between the cost and the amount of data used in the given equation.

2. Which of the following is the base that will bind with cytosine?

• A. Adenine
• B. Cytosine
• C. Guanine
• D. Thymine

Correct answer: A

Rationale: Adenine is the correct answer as it is the base that binds with cytosine through hydrogen bonding in DNA, forming the A-T base pair. Cytosine always pairs with guanine to form the G-C base pair. Thymine pairs with adenine in DNA, not with cytosine.

3. Which vitamin plays a vital role in immune function?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: Vitamin D is the correct answer. It plays a vital role in immune function by regulating the immune system and enhancing the pathogen-fighting effects of monocytes and macrophages. Deficiency in Vitamin D has been linked to increased susceptibility to infections and autoimmune diseases, highlighting its importance in maintaining a healthy immune response. Vitamin A (Choice A) is essential for vision and skin health but is not primarily known for its role in immune function. Vitamin B12 (Choice B) is important for red blood cell formation and neurological function, not specifically immune function. Vitamin E (Choice D) acts as an antioxidant and is beneficial for skin health and cell function, but it is not primarily associated with immune system support.

4. Select the correct verb to complete the following sentence: I _________ about it for a long time before I decided to major in criminal justice.

• A. think
• B. thank
• C. thinked
• D. thought

Correct answer: D

Rationale: The correct answer is 'thought.' 'Thought' is the correct past tense form of 'think.' In this sentence, 'thought' is used to indicate that the thinking process happened in the past before deciding to major in criminal justice. Choices A, B, and C are incorrect. 'Think' is the present tense form, 'thank' is a different verb with a different meaning, and 'thinked' is not a valid past tense form of 'think.'

5. What is the best summary of this article?

• A. The assassin who tried to kill President Lincoln and Secretary Seward escaped into the night. After having fired his pistol at the president, he barely eluded authorities and hurried to Seward's residence. There, he stabbed both the secretary and his son, Frederick Seward.
• B. A single assassin went on a rampage tonight, starting at Ford's Theater and absconding into the night. He currently remains at large.
• C. President Lincoln was shot by an assassin at Ford's Theater; the president is not expected to survive. Secretary Seward and his son were also attacked by an assassin at their home this evening. They remain unconscious, and their chances of survival are questionable. General Grant was scheduled to be at the theater, but changed his plans and was not harmed by the evening's events.
• D. General Grant is poised to take over the role of the presidency should President Lincoln die from wounds inflicted upon him at Ford's Theater. Grant was present at a recent Cabinet meeting, where Lincoln expressed hope for the future and spoke kind words about General Lee and the Confederacy.

Correct answer: C

Rationale: Choice C is the best summary of the article. It encapsulates the key events that occurred, including President Lincoln being shot at Ford's Theater, the attack on Secretary Seward and his son at their home, and General Grant avoiding harm. It accurately reflects the major developments and outcomes of the tragic events described in the article. Choices A, B, and D are incorrect because they either focus on specific aspects of the events and omit critical details or introduce irrelevant information not present in the article extract.
