1. Which of the following sentences from a paragraph about gingivitis is the topic sentence?

• A. Gingivitis can be reversed by daily brushing, flossing, and regular dental cleanings.
• B. Gingivitis is a mild form of gum disease, in which bacteria causes inflammation of the gums.
• C. With gingivitis, the gums become red and swollen and can bleed easily.
• D. If left untreated, gingivitis can cause periodontitis, in which the gums pull away from the teeth.

Correct answer: B

Rationale: The topic sentence in a paragraph typically introduces the main idea or topic of the paragraph. In this case, choice B correctly serves as the topic sentence by clearly stating that gingivitis is a mild form of gum disease caused by bacteria that leads to inflammation of the gums. Choices A, C, and D provide additional information that supports or follows the main idea but do not present the overarching topic of the paragraph.

2. Long bones are one of the five major types of bones in the human body. Which of the following bones are long bones?

• A. Sacrum
• B. Clavicle
• C. Patella
• D. Ulna, Fibula, Humerus

Correct answer: D

Rationale: Long bones are characterized by their elongated shape and include bones like the ulna, fibula, and humerus. These bones are crucial for providing support, structure, and facilitating movement in the human body. The sacrum, clavicle, and patella are not classified as long bones. The sacrum is a triangular bone at the base of the spine, the clavicle is a collarbone, and the patella is the kneecap. While these bones have important functions, they do not fit the definition of long bones due to their shape and structure.

3. How many centimeters are in 1 meter?

• A. 10 cm
• B. 100 cm
• C. 1,000 cm
• D. 10,000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. 1 meter is equivalent to 100 centimeters. Choice A (10 cm) is incorrect as it represents the conversion of decimeters to centimeters. Choice C (1,000 cm) is incorrect as it represents the conversion of meters to millimeters. Choice D (10,000 cm) is incorrect as it represents the conversion of meters to centimeters with an extra zero.

4. 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.

5. During embryonic development, all tissues originate from

• A. Epithelial tissue only
• B. Muscle tissue only
• C. Connective tissue only
• D. Embryonic germ layers

Correct answer: D

Rationale: During embryonic development, all tissues originate from the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various tissues and organs in the developing embryo through a process called gastrulation. Epithelial, muscle, and connective tissues are derived from these germ layers during development. Therefore, choices A, B, and C are incorrect as tissues do not originate from a single type of tissue but rather from the embryonic germ layers which differentiate into various tissues and organs.
