1. What is the central idea conveyed in the passage?

• A. David Foster Wallace's Infinite Jest is the holy grail of modern literature.
• B. Infinite Jest is a page-turner.
• C. David Foster Wallace wrote Infinite Jest.
• D. Infinite Jest is a modern classic for good reason and everybody should read it.

Correct answer: D

Rationale: The passage describes Infinite Jest as a modern classic that holds significant value, indicating that it is highly recommended for everyone to read it. Choice A focuses solely on the praise of the book without emphasizing the recommendation to read it. Choice B, mentioning it as a page-turner, does not capture the essence of it being a modern classic that everyone should read. Choice C is a factual statement about the authorship but does not encompass the main point that the book is a modern classic that deserves to be read by all.

2. Which part of the cell is responsible for storing genetic information?

• A. Ribosome
• B. Mitochondrion
• C. Nucleus
• D. Cytoplasm

Correct answer: C

Rationale: The correct answer is C, Nucleus. The nucleus is responsible for storing genetic information in the form of DNA. The DNA within the nucleus controls the activities of the cell by directing the synthesis of proteins and regulating gene expression. Choices A, Ribosome, B, Mitochondrion, and D, Cytoplasm, do not store genetic information. Ribosomes are involved in protein synthesis, mitochondria produce energy for the cell, and cytoplasm is a gel-like substance that houses organelles and where many cellular activities occur.

3. What describes the change in direction of light when it passes through different mediums, such as air and water?

• A. Diffraction
• B. Reflection
• C. Refraction
• D. Dispersion

Correct answer: C

Rationale: Refraction is the change in direction of light as it moves from one medium to another, such as air to water or glass. This change occurs due to variations in the speed of light in each medium, causing the light rays to bend. When light passes through different mediums, it changes its path, a phenomenon known as refraction. Choice A, Diffraction, refers to the bending of waves around obstacles and the spreading of waves when passing through small openings, not the change in direction of light when moving between mediums. Choice B, Reflection, is the bouncing back of light rays from a surface into the same medium, not the change in direction when transitioning between different mediums. Choice D, Dispersion, involves the separation of light into its constituent colors based on their different wavelengths, not the change in direction of light when passing through different mediums.

4. Why are elements in Group 18 (Noble gases) generally unreactive?

• A. They have high atomic masses
• B. They lack valence electrons
• C. Their outermost electron shells are completely filled
• D. They exist as single atoms, not molecules

Correct answer: C

Rationale: Elements in Group 18 (Noble gases) are generally unreactive because their outermost electron shells are completely filled. This results in high stability and low reactivity since they have achieved a full valence shell configuration, making them less likely to gain, lose, or share electrons with other atoms. The full valence shell configuration leads to a minimal tendency for these elements to form chemical bonds, hence exhibiting low reactivity. Choices A, B, and D are incorrect because high atomic masses, lack of valence electrons, and existing as single atoms do not directly contribute to the unreactivity of noble gases. It is the full valence shell configuration that is the primary reason for their inert nature.

5. Which of the following sentences indicates the end of a sequence?

• A. Our ultimate objective was to find a quality coat at an affordable price.
• B. We chose this particular restaurant because of its outdoor seating.
• C. Finally, we were able to settle in to enjoy the movie.
• D. Initially, it seemed unlikely that we’d be able to keep the puppy.

Correct answer: C

Rationale: The sentence 'Finally, we were able to settle in to enjoy the movie.' indicates the completion or conclusion of a sequence of events. The word 'finally' signals that something has been achieved or reached at the end of a series of actions or events. Choices A, B, and D do not indicate the end of a sequence but rather express different points within a series of events or actions.
