1. Based on the information in the passage, which of the composers among The Five would the author likely agree was the most influential?

• A. Alexander Glazunov
• B. Modest Mussorgsky
• C. Nikolai Rimsky-Korsakov
• D. Cesar Cui

Correct answer: C

Rationale: The correct answer is C: Nikolai Rimsky-Korsakov. The passage highlights Rimsky-Korsakov's significant influence by mentioning that composers such as Alexander Glazunov, Sergei Prokofiev, and Igor Stravinsky studied under him. This demonstrates that Rimsky-Korsakov had a lasting impact on the development of these renowned composers. Choice A, Alexander Glazunov, is incorrect because the passage states that Glazunov studied under Rimsky-Korsakov, indicating he was influenced by him rather than being the most influential among The Five. Choice B, Modest Mussorgsky, is incorrect as the passage mainly focuses on his works and contributions but does not mention his influence on other composers. Choice D, Cesar Cui, is incorrect as he is considered one of the founders of the movement but is not highlighted for influencing other significant composers as Rimsky-Korsakov is. Therefore, based on the information provided, the author would likely agree that Nikolai Rimsky-Korsakov was the most influential among The Five.

2. Select the meaning of the word 'somnambulist' in the sentence based on the context clues: 'If you wake up outside in your pajamas in the middle of the night, you may be a somnambulist.'

• A. Explorer
• B. Magician
• C. Insomniac
• D. Sleepwalker

Correct answer: D

Rationale: The correct answer is 'D: Sleepwalker.' A somnambulist is someone who walks or performs other activities while asleep, commonly known as a sleepwalker. In the given sentence, the context of waking up outside in pajamas in the middle of the night indicates an occurrence associated with sleepwalking. Choice A, 'Explorer,' is incorrect as it does not relate to the behavior described. Choice B, 'Magician,' is not related to the context of sleepwalking. Choice C, 'Insomniac,' refers to a person who has difficulty falling asleep or staying asleep, which is not the meaning conveyed in the sentence. Therefore, 'D: Sleepwalker' is the most appropriate choice based on the context clues provided.

3. What is the role of RNA interference in silencing genes?

• A. Increases protein production
• B. Promotes gene mutation
• C. Inhibits the expression of specific genes
• D. Repairs damaged DNA

Correct answer: C

Rationale: RNA interference (RNAi) is a biological process that involves the silencing of gene expression by inhibiting the translation of mRNA or by degrading mRNA molecules. This mechanism plays a crucial role in regulating gene expression and can be used to selectively silence specific genes. By interfering with the expression of specific genes, RNAi can downregulate protein production from those genes. Therefore, option C, 'Inhibits the expression of specific genes,' is the correct role of RNA interference in silencing genes. Options A, B, and D are incorrect because RNA interference does not increase protein production, promote gene mutation, or repair damaged DNA; its primary function is to inhibit gene expression by degrading or interfering with mRNA.

4. Most catalysts found in biological systems are which of the following?

• A. Special lipids called cofactors.
• B. Special proteins called enzymes.
• C. Special lipids called enzymes.
• D. Special proteins called cofactors.

Correct answer: B

Rationale: Enzymes are special proteins that act as catalysts in biological systems. They accelerate chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes play a critical role in the regulation of metabolic pathways and are essential for various biological processes. While some enzymes may require cofactors for activity, the enzymes themselves are the catalysts in biological systems. Therefore, choice B, special proteins called enzymes, is the most suitable answer. Choices A, C, and D are incorrect because enzymes, not lipids, are the primary catalysts in biological systems.

5. Which of the following statements about the passage is true?

• A. These cookies should be baked on a baking rack
• B. These cookies cannot be cooked in a microwave oven
• C. Folding in peanut butter must be done gently
• D. Beating egg whites involves stirring them vigorously

Correct answer: D

Rationale: The correct statement about the passage is that beating egg whites involves stirring them vigorously. In the provided extract, it mentions 'Beat egg white until foamy. Stir in sugar, beat again until stiff peaks form.' This process of beating the egg whites until stiff peaks form requires vigorous stirring. Choice A is incorrect because the passage does not mention using a baking rack for cooking the cookies. Choice B is incorrect as the passage provides instructions for baking the cookies in an oven. Choice C is incorrect as the passage does not emphasize the need for gentle folding when mixing in the peanut butter.
