1. In a study measuring the average hours worked per week by different types of hospital staff (such as nurses and physicians), what are the dependent and independent variables?

• A. The dependent variable is Nurses. The independent variable is Physicians.
• B. The dependent variable is Physicians. The independent variable is Nurses.
• C. The dependent variable is Hospital Staff. The independent variable is Average hours worked per week.
• D. The dependent variable is Average hours worked per week. The independent variable is Hospital Staff.

Correct answer: D

Rationale: In this study, the dependent variable is the 'Average hours worked per week,' as it relies on the different types of 'Hospital Staff' (the independent variable). The amount of time worked per week varies based on the category of staff being considered. Therefore, the correct choice is D. Choices A and B incorrectly assign the dependent and independent variables to specific staff categories (Nurses and Physicians), which are actually different elements within the study. Choice C incorrectly defines the dependent variable as 'Hospital Staff,' when in fact, it is the 'Average hours worked per week' that is dependent on the type of staff.

2. Futuristic Furniture gave the man two choices: pay the entire amount in one payment with cash, or pay $1000 as a down payment and $120 per month for two full years in the financing plan. If the man chooses the financing plan, how much more would he pay?

• A. $1480 more
• B. $1280 more
• C. $1600 more
• D. $2480 more

Correct answer: B

Rationale: If the man chooses the financing plan, he pays $1000 as a down payment initially. Over the two-year period, he will be paying $120 per month for a total of 24 months, which amounts to $120 x 24 = $2880. Therefore, the total amount he pays for the furniture through the financing plan is $1000 (down payment) + $2880 (monthly payments) = $3880. Comparing this total with the entire amount paid in one payment with cash would be $3880 - $3000 = $880 more. So, the man would pay $880 more if he chooses the financing plan. Therefore, the correct answer is $1280 more, not $1480, $1600, or $2480. These amounts do not accurately represent the additional cost incurred by choosing the financing plan.

3. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to separate fact from fiction. Which of the following describes this type of writing?

• A. Narrative
• B. Persuasive
• C. Expository
• D. Technical

Correct answer: C

Rationale: Expository writing is used to explain or inform, as seen in the factual account of the Bermuda Triangle. The passage provides information to explain the phenomenon of the Bermuda Triangle, presenting facts and details without attempting to persuade or tell a story (narrative) or focusing on technical details. While the Bermuda Triangle has inspired many stories and theories, the passage aims to inform rather than persuade or delve into technical aspects.

4. Which law of motion explains the behavior of rockets in space?

• A. Newton's First Law
• B. Newton's Second Law
• C. Newton's Third Law
• D. None of the above

Correct answer: C

Rationale: The correct answer is Newton's Third Law. Newton's Third Law states that for every action, there is an equal and opposite reaction. In the case of rockets in space, the action is the expulsion of gas from the rocket engines, and the reaction is the forward motion of the rocket. This law explains how rockets are able to propel themselves forward in the vacuum of space. Choices A and B are incorrect because Newton's First Law (inertia) and Second Law (F=ma) do not directly explain the behavior of rockets in space. Choice D is incorrect as Newton's Third Law specifically addresses the principle behind rockets' motion in space.

5. What is the condition called when someone experiences a temporary loss of consciousness due to a lack of blood flow to the brain?

• A. Stroke
• B. Epilepsy
• C. Syncope (fainting)
• D. Multiple sclerosis

Correct answer: C

Rationale: Syncope, also known as fainting, is a temporary loss of consciousness caused by a lack of blood flow to the brain. This can occur due to various reasons such as low blood pressure, dehydration, or sudden emotional stress. Strokes involve a disruption of blood flow to the brain resulting in brain cell damage. Epilepsy is a neurological disorder characterized by recurrent seizures. Multiple sclerosis is a chronic autoimmune disease that affects the central nervous system. In this case, the correct answer is 'Syncope' as it directly relates to the temporary loss of consciousness due to decreased blood flow to the brain, distinguishing it from the other options which involve different conditions affecting the nervous system.
