1. How many feet are in a mile?

• A. 1,000 ft
• B. 5,280 ft
• C. 2,000 ft
• D. 10,000 ft

Correct answer: B

Rationale: The correct answer is B: 5,280 feet in a mile. This is a standard conversion used in the Imperial system of measurement. Choice A, 1,000 ft, is incorrect as it is a common misconception and not the accurate conversion. Choice C, 2,000 ft, is also incorrect. Choice D, 10,000 ft, is significantly higher than the actual conversion and is incorrect. Remember, when converting miles to feet, the accurate value is 5,280 feet in a mile.

2. Bi, re, and un are:

• A. Suffixes, appearing at the beginning of base words to change their meaning
• B. Suffixes, appearing at the end of base words to enhance their meaning
• C. Prefixes, appearing at the beginning of base words to emphasize their meaning
• D. Prefixes, appearing at the beginning of base words to change their meaning

Correct answer: D

Rationale: Bi, re, and un are prefixes, not suffixes. Prefixes are added at the beginning of base words to change their meanings. Therefore, choices A, B, and C are incorrect because they refer to suffixes or emphasize, which is not the case for these prefixes.

3. Which of the following structures in the body is responsible for protecting the lungs and heart?

• A. Rib cage
• B. Pelvis
• C. Femur
• D. Vertebral column

Correct answer: A

Rationale: The rib cage is the correct answer. It plays a crucial role in protecting vital organs like the lungs and heart. The rib cage forms a protective barrier around these organs, shielding them from external trauma or injuries. It acts as a sturdy cage, offering structural support and safeguarding the delicate tissues and structures of the lungs and heart. The pelvis, femur, and vertebral column do not directly protect the lungs and heart; instead, they have other important functions in the body, such as supporting the body's weight, enabling movement, and protecting the spinal cord.

4. Which of the following structures helps filter pathogens from the blood?

• A. Lymph nodes
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: C

Rationale: The spleen is the correct answer. The spleen is a vital organ in the immune system responsible for filtering pathogens from the blood. It contains specialized immune cells that aid in recognizing and eliminating harmful substances. Additionally, the spleen plays a role in recycling old red blood cells. Choices A, B, and D are incorrect. Lymph nodes primarily filter lymph fluid, not blood. Kidneys are involved in filtering waste and regulating fluid balance, not specifically filtering pathogens from the blood. The pancreas functions in hormone regulation and digestion, unrelated to filtering pathogens from the blood.

5. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B correctly uses a semicolon to join two independent clauses related to the same event. In this sentence, 'The guests arrived' and 'Sarah greeted them at the door' are both independent clauses that are appropriately connected using a semicolon. Choice A incorrectly uses a semicolon before 'however,' which is a conjunction that should be preceded by a comma. Choice C incorrectly uses a semicolon to connect two independent clauses that are not closely related. Choice D incorrectly uses a semicolon to connect two independent clauses without a clear relationship or cohesion.
