1. What is the difference between two equal numbers?

• A. Negative
• B. Positive
• C. Zero
• D. Not enough information

Correct answer: C

Rationale: The difference between two numbers is found by subtracting one from the other. When two numbers are equal, subtracting them results in 0, because any number minus itself is always 0. Therefore, the difference between two equal numbers is always zero, making option C the correct answer. Option A ('Negative') and option B ('Positive') are incorrect as they do not represent the result of subtracting two equal numbers, which always yields zero. Option D ('Not enough information') is also incorrect as the difference between two equal numbers is definitively known to be zero.

2. Which of the following is an example of a complex sentence?

• A. Tabitha tried rock climbing, despite her fear of heights.
• B. Tabitha tried rock climbing; she had a fear of heights.
• C. Tabitha tried rock climbing and had a fear of heights.
• D. Tabitha tried rock climbing despite having a fear of heights.

Correct answer: D

Rationale: The correct answer is D. A complex sentence consists of an independent clause and at least one dependent clause. In this case, 'Tabitha tried rock climbing' is the independent clause, and 'despite having a fear of heights' is the dependent clause, making it a complex sentence. Choice A has been corrected to include a complete dependent clause, 'despite her fear of heights.' Choice B is incorrect because the semicolon does not appropriately connect the clauses. Choice C is incorrect as it combines two independent clauses without a dependent clause. Therefore, only choice D correctly forms a complex sentence with an independent and dependent clause.

3. Which of the following can be logically inferred from the passage?

• A. The Vikings disliked exploring the New World.
• B. Leif Erikson's banishment led to his exploration of Canada.
• C. Leif Erikson never shared his stories with the King of Norway.
• D. Historians have difficulty pinpointing events in Viking history.

Correct answer: D

Rationale: The correct answer is D. It can be inferred from the passage that historians have difficulty definitively pinpointing Viking historical events. The passage highlights the uncertainty around Leif Erikson's birth year, conflicting accounts of interactions with natives, and the lack of clarity regarding specific events in Viking history. Choices A, B, and C are incorrect. There is no indication in the passage that the Vikings disliked exploring the New World; Leif Erikson's banishment did not directly lead to his exploration of Canada but rather his desire to spread Christianity and find new lands; and there is no mention of Leif Erikson not sharing his stories with the King of Norway.

4. Curtis is taking a road trip through Germany, where all distance signs are in metric. He passes a sign that states the city of Dusseldorf is 45 kilometers away. Approximately how far is this in miles?

• A. 42 miles
• B. 37 miles
• C. 28 miles
• D. 16 miles

Correct answer: C

Rationale: To convert kilometers to miles, you can use the conversion factor of approximately 0.62 miles per kilometer. Therefore, 45 kilometers × 0.62 miles/kilometer = 27.9 miles, which is approximately 28 miles away. Choice A (42 miles), Choice B (37 miles), and Choice D (16 miles) are incorrect as they do not reflect the accurate conversion from kilometers to miles.

5. What is the primary function of B cells in the immune system?

• A. Directly attacking and engulfing pathogens
• B. Producing antibodies specific to a pathogen
• C. Destroying infected body cells
• D. All of the above

Correct answer: B

Rationale: B cells are a type of white blood cell that primarily functions by producing antibodies specific to a pathogen. These antibodies play a crucial role in marking pathogens for destruction by other immune cells. While B cells are essential for the immune response, they do not directly attack and engulf pathogens or destroy infected body cells. These functions are carried out by other immune cells like macrophages and cytotoxic T cells. Therefore, the correct answer is B, as it accurately reflects the primary role of B cells in the immune system.
