1. What is the external body covering, providing protection and contributing to temperature regulation, composed of?

• A. Muscle tissue
• B. Epithelial tissue (skin)
• C. Bone marrow
• D. Cartilage

Correct answer: B

Rationale: The external body covering, which is the skin, is composed of epithelial tissue. Epithelial tissue serves as a protective barrier against pathogens, chemicals, and physical damage. It also helps regulate body temperature through processes like sweating. Choice A (Muscle tissue) is incorrect as muscles are responsible for movement and not the external body covering. Choice C (Bone marrow) is incorrect as it is a component of the skeletal system and not the external body covering. Choice D (Cartilage) is incorrect as cartilage is a type of connective tissue found in joints and the structure of some body parts, not the external body covering.

2. Which of the following is an appropriately-punctuated correction for this sentence: Protestors filled the streets of the city because they were dissatisfied with the government's leadership?

• A. Protestors filled the streets of the city, because they were dissatisfied with the government's leadership.
• B. Protesters, filled the streets of the city, because they were dissatisfied with the government's leadership.
• C. Because they were dissatisfied with the government's leadership protestors filled the streets of the city.
• D. Protestors filled the streets of the city because they were dissatisfied with the government's leadership.

Correct answer: D

Rationale: The correct answer is D. The sentence should be corrected by removing the period and joining the clauses to avoid a sentence fragment. Choice A is incorrect due to the unnecessary comma after 'city.' Choice B is incorrect as it mistakenly separates the subject and verb with a comma. Choice C is incorrect as it begins with the subordinate clause, disrupting the logical flow of the sentence.

3. Which verb tense is most appropriate to complete this sentence: 'By next week, I _____ the project'?

• A. I will be finishing
• B. I will have finished
• C. I am finishing
• D. I would finish

Correct answer: B

Rationale: The correct answer is option B, 'I will have finished'. This choice correctly expresses a future event (finishing the project) that will be completed before another future point in time (next week). The future perfect tense 'will have finished' is used to show an action that will be completed before a specified future time. Choice A, 'I will be finishing', is incorrect as it indicates an ongoing action that will still be in progress by next week, which is not the intended meaning. Choice C, 'I am finishing', is incorrect as it indicates a present action that is ongoing, not a future event. Choice D, 'I would finish', is incorrect as 'would' is used for hypothetical situations or polite requests, which is not suitable in this context of a future project completion.

4. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective 'enthusiastic'?

• A. enthusiastic
• B. enthusiastically
• C. enthusiasm
• D. enthuse

Correct answer: C

Rationale: The correct answer is 'C: enthusiasm.' The noun form of the adjective 'enthusiastic' is 'enthusiasm.' Nouns are often formed from adjectives by changing the suffix; in this case, '-ic' in 'enthusiastic' changes to '-m' in 'enthusiasm.' 'Entusiastic' is an adjective and does not function as a noun. 'Enthusiastically' is an adverb as it describes how something is done, not a noun. 'Enthuse' is a verb and does not represent the noun form of 'enthusiastic.' It is important to understand the relationships between different parts of speech when analyzing word forms.

5. What happens to the density of a substance if its mass increases while its volume remains constant?

• A. Density increases
• B. Density decreases
• C. Density remains constant
• D. Density becomes zero

Correct answer: A

Rationale: When the mass of a substance increases while its volume remains constant, the density, which is calculated by dividing mass by volume, will increase. This is because with a higher mass and the volume staying the same, the ratio of mass to volume (density) will be greater, resulting in an overall increase in density. Choice B, 'Density decreases,' is incorrect because an increase in mass with constant volume leads to a higher density. Choice C, 'Density remains constant,' is incorrect as an increase in mass will cause the density to increase. Choice D, 'Density becomes zero,' is incorrect because even with an increase in mass, as long as volume remains constant, density will not reach zero; it will increase instead.
