1. Which of the following words in the sentence is an adverb? We should go outside.

• A. We
• B. should
• C. go
• D. outside

Correct answer: D

Rationale: The word 'outside' is the adverb in the sentence. An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'outside' modifies the verb 'go' by indicating the location where the action is taking place. Choices A, B, and C are incorrect because 'We' is a pronoun, 'should' is a modal verb, and 'go' is the main verb in the sentence, none of which function as adverbs.

2. Which of the following sources would be the best to understand the suspense genre better?

• A. A public library's digital catalog
• B. The online reviews of the genre
• C. A New York Times bestseller list
• D. An encyclopedia entry about the suspense genre

Correct answer: D

Rationale: The correct answer is D, an encyclopedia entry about the suspense genre. This choice would be the best source to understand the suspense genre better as it provides a comprehensive and detailed overview of the genre's history, characteristics, and key elements. Option A, a public library's digital catalog, may list suspense novels available but does not offer in-depth information about the genre itself. Option B, online reviews of the genre, are subjective opinions and may not provide a holistic view of the genre. Option C, a New York Times bestseller list, showcases popular titles but doesn't delve into the specifics of the suspense genre.

3. Which part of the brain is responsible for controlling involuntary actions like breathing and heart rate?

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

Correct answer: B

Rationale: The correct answer is the Medulla oblongata. This region of the brain is located in the brainstem and is responsible for controlling vital autonomic functions such as breathing, heart rate, and blood pressure. The Cerebellum (Choice A) is primarily involved in coordination and balance. The Cerebrum (Choice C) is responsible for higher brain functions like thinking and voluntary muscle movement. The Thalamus (Choice D) acts as a relay station for sensory information but is not primarily responsible for controlling involuntary actions like breathing and heart rate.

4. What controls muscles by sending electrical impulses to the muscles?

• A. Blood vessels
• B. Nerves
• C. Hormones
• D. Neurons

Correct answer: B

Rationale: Nerves control muscles by transmitting electrical impulses that initiate muscle contractions. Blood vessels are responsible for transporting blood, not controlling muscles. Hormones are chemical messengers produced by glands to regulate bodily functions, not specifically controlling muscles. Neurons are the basic building blocks of the nervous system that transmit signals, but nerves are the specific structures that control muscles by sending electrical impulses.

5. What is the importance of RNA splicing?

• A. Removes introns from the mRNA molecule
• B. Adds the poly-A tail to the mRNA molecule
• C. Activates the mRNA molecule for translation
• D. Modifies the structure of the protein

Correct answer: A

Rationale: RNA splicing is a crucial process in gene expression where non-coding regions called introns are removed from the pre-mRNA molecule, and the remaining coding regions called exons are joined together to form the mature mRNA molecule. This process ensures that only the protein-coding sequences are retained in the mRNA for translation, allowing for the production of functional proteins. Therefore, option A is the correct answer as it accurately describes the importance of RNA splicing in generating mature mRNA molecules for protein synthesis. B) Adding the poly-A tail to the mRNA molecule is a post-transcriptional modification that occurs after RNA splicing and is not directly related to the process of removing introns. C) Activating the mRNA molecule for translation is typically achieved through the addition of a 5' cap and the poly-A tail, rather than through RNA splicing. D) Modifying the structure of the protein is not directly related to the process of RNA splicing, which primarily focuses on mRNA maturation by removing non-coding introns.
