1. Which of the following is not a simple sentence?

• A. Agatha Christie was the author of more than sixty detective novels.
• B. Her most famous detectives were Hercule Poirot and Miss Marple.
• C. She also wrote over fifteen collections of short stories about these detectives.
• D. Most readers favor Poirot, but Christie preferred Miss Marple. Hercule Poirot is remembered not only for his genius in solving mysteries, but also for his fastidious habits and his commitment to personal grooming.

Correct answer: D

Rationale: Option D is not a simple sentence because it contains multiple independent clauses joined by conjunctions ('but' and 'and'). Simple sentences consist of a single independent clause, which is a complete sentence with a subject and a verb that expresses a complete thought on its own. In contrast, option D includes multiple independent clauses about Hercule Poirot, his habits, and Miss Marple, making it a compound sentence rather than a simple one. Choices A, B, and C are all simple sentences as they each express a single complete thought with a subject and a verb, without joining multiple independent clauses together.

2. Which of the following statements best expresses the main idea of the passage?

• A. Getting a job is easier now than it ever has been before.
• B. Earning money is much less difficult than managing it properly.
• C. Dr. Franklin advocated getting a job in a mill.
• D. Spending money is the greatest temptation in the world.

Correct answer: B

Rationale: The main idea of the passage is that while making money may seem easy, managing it wisely is much more challenging. The author emphasizes the importance of spending less than what is earned to achieve financial stability. Choice A is incorrect as the passage focuses on the challenges of managing money, not on the ease of getting a job. Choice C is incorrect as Dr. Franklin is mentioned in the context of a quote about the simplicity of the road to wealth, not advocating getting a job in a mill. Choice D is incorrect as the passage does not primarily discuss spending money as the greatest temptation, but rather highlights the difficulty in managing money effectively.

3. What type of intermolecular force is responsible for the high surface tension of water?

• A. Hydrogen bonding
• B. London dispersion forces
• C. Ionic bonding
• D. Metallic bonding

Correct answer: A

Rationale: The high surface tension of water is primarily due to the strong hydrogen bonding between water molecules. Hydrogen bonding is a specific type of intermolecular force that occurs between a hydrogen atom covalently bonded to a highly electronegative atom, like oxygen in water, and another electronegative atom nearby. This unique interaction results in a strong attraction between water molecules at the surface, leading to the cohesive forces responsible for the high surface tension of water. Choices B, C, and D are incorrect because London dispersion forces, ionic bonding, and metallic bonding do not account for the high surface tension observed in water. London dispersion forces are relatively weaker intermolecular forces, while ionic and metallic bonding are types of intramolecular forces that do not directly contribute to the surface tension of water.

4. What is the name of the structure that packages DNA in eukaryotic cells?

• A. Nucleosome
• B. Chromatin
• C. Histone
• D. Centromere

Correct answer: A

Rationale: - A nucleosome is the basic structural unit of DNA packaging in eukaryotic cells. It consists of DNA wrapped around a core of histone proteins. - Chromatin refers to the complex of DNA and proteins found in the nucleus of a eukaryotic cell, including nucleosomes. - Histones are the proteins around which DNA is wrapped to form nucleosomes. - Centromere is a region of a chromosome where the two sister chromatids are joined and to which spindle fibers attach during cell division.

5. What is the term for the phenomenon when two waves combine to form a new wave?

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

Correct answer: B

Rationale: The correct answer is B: Interference. Interference is the term used to describe the phenomenon when two waves combine to form a new wave. When waves interact constructively or destructively, they interfere with each other, resulting in a new wave pattern. Choice A, Diffraction, refers to the bending of waves around obstacles, not the combination of waves. Choice C, Refraction, is the bending of waves as they pass from one medium to another, not the combination of waves. Choice D, Dispersion, is the separation of light into its different colors, not the combination of waves.
