1. How is blood pressure controlled by the body?

• A. By adjusting heart rate only
• B. By regulating blood volume
• C. By baroreceptors and hormones
• D. By adjusting body temperature

Correct answer: C

Rationale: Blood pressure is controlled by baroreceptors located in the aortic arch and carotid arteries that detect changes in blood pressure levels. When blood pressure is high, these receptors signal for adjustments to lower it. Additionally, hormones such as renin from the kidneys are released when blood pressure drops, further aiding in blood pressure regulation. Choice A is incorrect because blood pressure regulation involves more than just adjusting heart rate; it also includes vasodilation and vasoconstriction. Choice B is incorrect as while blood volume can impact blood pressure, it is not the primary mechanism of blood pressure control. Choice D is incorrect as body temperature regulation is a separate physiological process and not directly related to blood pressure control.

2. Which option best defines a fable?

• A. A melancholic poem lamenting the subject's death
• B. An oral tradition influenced by culture
• C. A story with events that occur in threes and sevens
• D. A short story with animals, fantastic creatures, or other forces within nature

Correct answer: D

Rationale: A fable is a short story that typically features animals, fantastic creatures, or other forces within nature as characters. These characters often possess human-like qualities and behavior, and the story is intended to convey a moral lesson or message to the reader. The use of animals or other natural elements is a common characteristic of fables, distinguishing them from other types of stories or literary works. Options A, B, and C are incorrect because they do not accurately describe the defining characteristics of a fable.

3. The hypodermis is primarily composed of which tissue?

• A. Adipose
• B. Connective
• C. Epithelial
• D. Muscle

Correct answer: A

Rationale: The hypodermis, also known as the subcutaneous layer, is primarily composed of adipose (fat) tissue. Adipose tissue in the hypodermis serves as an insulator, energy reserve, and cushioning for the body. Choice B, Connective tissue, is a broad category that includes various types of tissue like adipose, but the hypodermis is specifically rich in adipose tissue. Choice C, Epithelial tissue, is not the primary component of the hypodermis; it is mainly found covering body surfaces and lining cavities. Choice D, Muscle tissue, is not a major component of the hypodermis; muscle tissue is mainly located deeper in the body and serves in movement and support functions.

4. What is the function of the underlined phrase 'with a mischievous grin' in the sentence 'He approached her with a mischievous grin, his eyes twinkling'?

• A. Subject
• B. Direct object
• C. Adverbial phrase
• D. Appositive phrase

Correct answer: C

Rationale: The underlined phrase 'with a mischievous grin' functions as an adverbial phrase in the sentence. It modifies the verb 'approached' by providing information on how he approached her, describing his manner. Adverbial phrases typically answer questions like 'how,' 'when,' 'where,' 'why,' or 'to what extent,' which this phrase does by indicating the manner in which he approached. Choices A, B, and D are incorrect. The phrase does not serve as a subject (A), direct object (B), or appositive phrase (D) in the sentence. Instead, it functions to provide additional information about the action of approaching, making it an adverbial phrase.

5. Which sentence uses the pronoun 'they' correctly?

• A. They is going to the park later today.
• B. Sarah and John said they would come to the party.
• C. The teacher said they needs to finish the report.
• D. They enjoys reading books in their free time.

Correct answer: B

Rationale: A. "They" should be used with "are," not "is." B. Correct use of "they" for multiple people (Sarah and John). C. "They" should not be paired with "needs." D. "They" should be used with "enjoy," not "enjoys."
