1. What defines a composite number?

• A. A number with only two factors
• B. A number that is a fraction
• C. A number with more than 2 factors
• D. A number with exactly two factors

Correct answer: C

Rationale: A composite number is a positive integer greater than one that has more than two factors. Choice A is incorrect because a number with only two factors is a prime number. Choice B is incorrect as being a fraction does not define a composite number. Choice D is incorrect because a number with exactly two factors is a prime number, not a composite number.

2. 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.

3. Solve for y: 2y + 5 = 25 * 10

• A. y = 25
• B. y = 100
• C. y = 150
• D. y = 200

Correct answer: B

Rationale: To solve the equation 2y + 5 = 25 * 10, start by simplifying the right side: 25 * 10 = 250. Then, subtract 5 from both sides to isolate 2y: 2y = 250 - 5 = 245. Finally, divide by 2 to find the value of y: y = 245 / 2 = 122.5. Therefore, the correct answer is y = 122.5. Choices A, C, and D are incorrect as they do not result from the correct calculation steps.

4. Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?

• A. Lack of suitable materials to handle high temperatures and pressures.
• B. Limited availability of fusion fuels like deuterium and tritium.
• C. Difficulty in containing the plasma where fusion occurs.
• D. All of the above

Correct answer: D

Rationale: The main obstacle to achieving controlled nuclear fusion on Earth for energy production involves a combination of factors. A) Lack of suitable materials to handle high temperatures and pressures is a significant challenge due to the extreme conditions required for fusion reactions. B) Limited availability of fusion fuels like deuterium and tritium can pose a constraint on the scalability and sustainability of fusion energy. C) Difficulty in containing the plasma where fusion occurs is another critical issue as plasma instabilities and heat losses can hinder the efficiency of fusion reactions. Therefore, all of the options (A, B, and C) contribute to the challenges in achieving controlled nuclear fusion for energy production on Earth.

5. Which of the following lines from the passage supports the inference that Hedy Lamarr worked earnestly to achieve her goals?

• A. She began starring in American films with MGM studios in the late 1930s and early 1940s
• B. She even spent time working with the science engineering team employed by Howard Hughes, the aviation tycoon
• C. Her roles generally did not include very many spoken lines and she became bored
• D. ... but she did not allow that to stop her from teaching herself in her spare time.

Correct answer: D

Rationale: The correct answer is D, as it showcases Hedy Lamarr's determination and hard work towards achieving her goals. Despite facing challenges, such as not having many spoken lines in her roles, she persevered by teaching herself in her spare time. Choice A talks about her success in starring in American films but does not directly relate to her working earnestly. Choice B mentions her collaboration with Howard Hughes' science engineering team, which indicates involvement but not necessarily hard work towards personal goals. Choice C describes her becoming bored due to the lack of spoken lines in her roles and does not highlight her dedication and effort to achieve her aspirations.
