1. How are the bones of the skull classified?

• A. Long bones
• B. Short bones
• C. Flat bones
• D. Irregular bones

Correct answer: C

Rationale: The bones of the skull are classified as flat bones. Flat bones are thin, flattened, and usually curved bones that provide protection to underlying organs and have a large surface area for muscle attachment. The skull bones fit this description as they protect the brain and have a broad surface for muscle attachment. Choice A (Long bones), B (Short bones), and D (Irregular bones) are incorrect classifications. Long bones are typically found in the extremities like the arms and legs, short bones are cube-shaped like the wrist and ankle bones, and irregular bones have complex shapes like the vertebrae. These classifications do not describe the bones of the skull, which are predominantly flat bones.

2. Which of the following is the complete subject of the following sentence? All of Shannon’s family and friends helped her to celebrate her 50th birthday at Café Sorrento.

• A. Family and friends
• B. All
• C. All of Shannon’s family and friends
• D. Shannon’s family and friends

Correct answer: C

Rationale: The complete subject in the sentence is 'All of Shannon’s family and friends.' This phrase encompasses the entirety of the group involved in celebrating Shannon’s 50th birthday at Café Sorrento. It includes both her family and friends collectively, highlighting the full extent of individuals who participated in the celebration. The term 'All of Shannon’s family and friends' is essential for providing a comprehensive subject that covers everyone who contributed to making the event special. Choices A, B, and D are incorrect because they do not capture the complete scope of individuals involved in the birthday celebration, unlike choice C which encompasses both Shannon’s family and friends.

3. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?

• A. 0.5 moles
• B. 1 mole
• C. 2 moles
• D. 3 moles

Correct answer: B

Rationale: The balanced chemical equation for the combustion of methane is: CH4 + 2O2 -> CO2 + 2H2O. This equation shows that 1 mole of methane produces 2 moles of water. Therefore, when 0.5 moles of methane react, they will produce 1 mole of water. The ratio of water to methane is 2:1, meaning that for every mole of methane that reacts, it produces 2 moles of water. Since only 0.5 moles of methane are reacting, the amount of water produced will be half of what would be produced if 1 mole of methane reacted, resulting in 1 mole of water being produced. Choice A is incorrect because it does not consider the stoichiometry of the reaction. Choices C and D are incorrect as they do not align with the balanced chemical equation and the stoichiometric ratios involved in the reaction.

4. Which type of joint allows for the most movement?

• A. Ball-and-socket joint (shoulder)
• B. Hinge joint (elbow)
• C. Fibrocartilaginous joint (wrists)
• D. Suture joint (skull)

Correct answer: A

Rationale: The correct answer is A: Ball-and-socket joint (shoulder). Ball-and-socket joints, exemplified by the shoulder joint, provide the widest range of movement among joint types. These joints facilitate flexion, extension, abduction, adduction, and rotation, allowing for versatile mobility. In a ball-and-socket joint, the rounded end of one bone fits into the socket of another bone, enabling extensive motion capabilities. Choice B, Hinge joint (elbow), allows movement in one plane, limiting its range compared to ball-and-socket joints. Choice C, Fibrocartilaginous joint (wrists), like the intervertebral discs, is meant for stability rather than extensive movement. Choice D, Suture joint (skull), found in the skull bones, is immovable and provides structural support rather than movement.

5. In the following sentence, which part of speech does the word 'capacity' function as?

• A. Verb
• B. Noun
• C. Adverb
• D. Pronoun

Correct answer: B

Rationale: In the sentence, 'capacity' is used to refer to the maximum amount that something can contain or produce, making it a noun. It is not functioning as a verb (choice A), as it is not describing an action. It is not an adverb (choice C) because it is not modifying a verb, adjective, or another adverb. Additionally, it is not a pronoun (choice D) because it is not replacing a noun or noun phrase. Therefore, the correct answer is 'B: Noun.'
