1. What kinds of clauses does the following sentence contain? "Although Ted had an impressive education, he had little experience working with individuals, which made him less effective at relating to them."

• A. Two dependent clauses and one independent clause
• B. One dependent clause and two independent clauses
• C. Two independent clauses and no dependent clauses
• D. One dependent clause and one independent clause

Correct answer: B

Rationale: The sentence consists of one dependent clause, 'Although Ted had an impressive education,' which introduces a condition. It also contains two independent clauses: 'he had little experience working with individuals,' which presents a fact, and 'which made him less effective at relating to them,' which provides additional information. Therefore, the correct answer is B. Choice A is incorrect because it incorrectly identifies the number of independent and dependent clauses. Choice C is incorrect as it wrongly states that there are no dependent clauses in the sentence. Choice D is incorrect as it does not accurately represent the structure of the sentence.

2. What is the main function of the epiglottis, a small flap of cartilage located above the larynx?

• A. To warm and humidify inhaled air
• B. To control the passage of food and air
• C. To produce sound vibrations for speech
• D. To sense the presence of foreign objects

Correct answer: B

Rationale: The main function of the epiglottis is to control the passage of food and air. It acts as a cover for the trachea during swallowing to prevent food from entering the airway. This mechanism ensures that food safely travels down the esophagus to the stomach, while air simultaneously enters the trachea and moves into the lungs for respiration. Choice A is incorrect as the warming and humidifying of inhaled air primarily occur in the nasal cavity. Choice C is incorrect because sound production for speech involves structures like the vocal cords rather than the epiglottis. Choice D is incorrect as sensing foreign objects is not a primary function of the epiglottis; instead, this role is typically associated with sensory receptors in the respiratory tract.

3. At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim's house and gives him 6 of his apples. He then uses 3/4 of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?

• A. 4
• B. 6
• C. 2
• D. 1

Correct answer: D

Rationale: Xavier gives away half of his 20 apples (10), then gives 6 more apples, leaving him with 4 apples. He uses 3/4 of the remaining 4 apples (3) for the pie, leaving him with 1 apple at the end of the day. Therefore, the correct answer is 1. Choices A, B, and C are incorrect because they do not accurately reflect the calculations of apples given away and used for the pie, resulting in the remaining amount of 1 apple.

4. Which of the following processes breaks down cellular components for recycling or waste removal?

• A. Photosynthesis
• B. Cellular respiration
• C. Cell division
• D. Phagocytosis

Correct answer: D

Rationale: The correct answer is D: Phagocytosis. Phagocytosis is the process by which cells engulf and break down cellular components or foreign particles for recycling or waste removal. It is a vital mechanism used by cells to maintain homeostasis and remove waste materials. Photosynthesis (A) is the process by which plants convert light energy into chemical energy to produce food, not for breaking down cellular components. Cellular respiration (B) is the process by which cells generate energy from nutrients, not for waste removal. Cell division (C) is the process by which cells replicate and divide to form new cells during growth, repair, or development, not for breaking down cellular components.

5. Which part of the brain controls balance and coordination?

• A. Cerebrum
• B. Cerebellum
• C. Medulla
• D. Thalamus

Correct answer: B

Rationale: The cerebellum is the correct answer as it is the part of the brain responsible for controlling balance and coordination in the body. It receives input from various parts of the brain, spinal cord, and sensory systems to help coordinate voluntary movements. The cerebrum (choice A) is mainly involved in higher brain functions such as thinking, decision-making, and voluntary movements but not specifically balance and coordination. The medulla (choice C) is essential for functions like breathing, heart rate, and blood pressure regulation but not primarily for balance and coordination. The thalamus (choice D) acts as a relay station for sensory information but is not primarily responsible for balance and coordination.
