1. Which of the following is a primary source that would be relevant to a biography about Jules Verne?

• A. Articles about Jules Verne written after his death
• B. Reviews of Jules Verne’s works
• C. Film adaptations of Jules Verne’s works
• D. Letters exchanged by Jules Verne and a close friend

Correct answer: D

Rationale: The correct answer is D. Letters exchanged by Jules Verne and a close friend would be a primary source as they were written during his lifetime, providing direct insight into his thoughts and actions. Choices A, B, and C are not primary sources. Articles written after his death, reviews of his works, and film adaptations are considered secondary sources as they are interpretations or analyses based on primary materials.

2. During swallowing, what is the role of the epiglottis, a small flap of cartilage located near the base of the tongue?

• A. Initiates the swallowing reflex
• B. Grinds food into smaller pieces
• C. Covers the trachea to prevent food aspiration
• D. Stores saliva for lubrication

Correct answer: C

Rationale: The epiglottis plays a crucial role during swallowing by covering the trachea to prevent food or liquid from entering the airway, which could lead to aspiration. By acting as a lid over the trachea, it ensures that food passes down the esophagus to the stomach, preventing it from entering the lungs. Choice A is incorrect as the swallowing reflex is a coordinated muscular action involving the tongue and throat muscles. Choice B is incorrect as grinding food into smaller pieces is primarily the function of the teeth and the initial stages of digestion. Choice D is incorrect as the storage of saliva for lubrication is not a function of the epiglottis, but rather involves salivary glands.

3. What is the primary function of nervous tissue?

• A. Movement
• B. Protection
• C. Communication and coordination
• D. Nutrient transport

Correct answer: C

Rationale: The primary function of nervous tissue is communication and coordination within the body. Nervous tissue is composed of neurons that transmit electrical signals and supporting cells known as neuroglia. Movement is primarily controlled by the muscular system, protection is mainly provided by the skeletal system and immune system, and nutrient transport is carried out by the circulatory system. Therefore, choices A, B, and D are incorrect as they do not align with the primary function of nervous tissue.

4. Raoul has an upcoming school project, and his own computer is not working. He needs to use the library computer, and he has estimated that he will need to be on the computer for approximately an hour and a half. How much of a fee can Raoul expect to pay for his computer use at the library?

• A. $6
• B. $9
• C. $12
• D. $15

Correct answer: C

Rationale: Raoul needs to use the computer for 90 minutes. The first 30 minutes are free, so he would pay for the remaining 60 minutes, which is 4 intervals of 15 minutes each. Each 15-minute period incurs a $3 charge, so for 60 minutes, Raoul would pay 4 x $3 = $12. Therefore, Raoul can expect to pay $12 for his computer use at the library. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. What is the function of the stratified cuboidal epithelium lining the salivary glands?

• A. Protection
• B. Gas exchange
• C. Secretion
• D. Absorption

Correct answer: C

Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is responsible for secretion. This type of epithelium, made of multiple layers of cube-shaped cells, is specialized for secretion and protection. In the salivary glands, these cells secrete saliva to aid in the digestion process. Choice A, Protection, is incorrect because while the epithelium does provide some level of protection, its primary function in the salivary glands is secretion. Choice B, Gas exchange, is incorrect as the salivary glands are not involved in gas exchange processes. Choice D, Absorption, is also incorrect as the main role of this epithelium in the salivary glands is not absorption but rather secretion of saliva.
