1. The important decision will be made tomorrow. Which word is the comparative form of the adjective 'important'?

• A. important
• B. importantly
• C. more important
• D. most important

Correct answer: C

Rationale: In this sentence, 'important' is the positive form of the adjective. When comparing two things, the comparative form is used, which is 'more important' in this case. 'More important' indicates a higher degree of importance when comparing two things. Therefore, 'more important' is the correct comparative form of the adjective 'important' in this context. Choice A ('important') is the positive form, not the comparative form. Choice B ('importantly') is an adverb, not a comparative form of the adjective. Choice D ('most important') is the superlative form, used to show the highest degree of importance among three or more things, not for comparing two things.

2. If a person spends 1/4 of their day sleeping, how many hours do they spend sleeping?

• A. 6 hours
• B. 8 hours
• C. 4 hours
• D. 5 hours

Correct answer: A

Rationale: To calculate the number of hours a person spends sleeping when 1/4 of the day is spent sleeping, you need to find 1/4 of 24 hours. 1/4 of 24 hours is 6 hours, so the correct answer is A. Choice B (8 hours) is incorrect because it does not correspond to 1/4 of a day. Choice C (4 hours) is incorrect as it is half of the correct answer. Choice D (5 hours) is incorrect as it does not match the calculation for 1/4 of a day.

3. What part of speech is the word 'silently' in the sentence 'The masked villain silently laughed while watching the hero struggle to escape'?

• A. Preposition
• B. Adverb
• C. Verb
• D. Adjective

Correct answer: B

Rationale: 'Silently' is an adverb in this sentence as it describes how the villain laughed. Adverbs modify verbs, adjectives, or other adverbs. In this case, 'silently' is modifying the verb 'laughed,' indicating the manner in which the action was performed. Choices A, C, and D are incorrect. 'Silently' is not a preposition (A) as it doesn't show a relationship between nouns or pronouns. It is not a verb (C) because it doesn't express an action or state of being. Additionally, it is not an adjective (D) since it does not describe a noun or pronoun.

4. Which element has the same number of protons and neutrons?

• A. Carbon (C)
• B. Oxygen (O)
• C. Lithium (Li)
• D. Helium (He)

Correct answer: D

Rationale: The correct answer is Helium (He). Helium has an atomic number of 2, meaning it has 2 protons. It also has 2 neutrons, which gives it a total mass number of 4. Therefore, Helium is an example of an element with an equal number of protons and neutrons. Choice A (Carbon) has 6 protons and usually has more neutrons than protons. Choice B (Oxygen) has 8 protons and 8 neutrons, so the numbers are not equal. Choice C (Lithium) has 3 protons and usually has more neutrons than protons, so it does not fit the criteria of having the same number of protons and neutrons.

5. What structures provide comprehensive protection for the brain?

• A. Skull
• B. Meninges (Membranes)
• C. Cerebrospinal fluid
• D. All of the above

Correct answer: D

Rationale: The brain is a vital organ that requires robust protection, which is provided by a combination of structures. The skull acts as a hard, protective covering for the brain, shielding it from external trauma and injury. The meninges encompass three layers of membranes (dura mater, arachnoid mater, and pia mater) that envelop the brain and spinal cord, offering additional protection and cushioning. Cerebrospinal fluid, a clear, colorless fluid surrounding the brain and spinal cord, acts as a shock absorber and provides nutrients to the central nervous system. The combined function of the skull, meninges, and cerebrospinal fluid ensures comprehensive protection for the brain, making option D, 'All of the above,' the correct answer. Choices A, B, and C are not individually sufficient to provide comprehensive protection, but together, they form a multi-layered defense system for the brain.
