1. What unit is used for measuring luminous flux, which indicates the perceived brightness of a light source by the human eye?

• A. Candela
• B. Lumen
• C. Lux
• D. Hertz

Correct answer: B

Rationale: Lumen is the correct unit for measuring luminous flux, which quantifies the total visible light emitted by a source per unit of time. Candela measures luminous intensity, lux measures illuminance, and Hertz measures frequency. Therefore, in the context of measuring the perceived brightness of a light source by the human eye, luminous flux is quantified in lumens.

2. What is the purpose of the first paragraph in relation to the second paragraph?

• A. The first paragraph serves as a cause and the second paragraph serves as an effect.
• B. The first paragraph serves as a contrast to the second.
• C. The first paragraph is a description for the argument in the second paragraph.
• D. The first and second paragraphs are merely presented in a sequence.

Correct answer: A

Rationale: The first paragraph introduces the general characteristics of insects and their ability to live both on land and in the air, setting the stage for discussing specific examples in the second paragraph. The second paragraph then delves into examples of insects that transition from living underwater to the aerial phase, establishing a cause-and-effect relationship between the general concept introduced in the first paragraph and the specific examples in the second paragraph. Choice A is correct because the first paragraph gives the cause (insects being creatures of land and air) and the second paragraph provides the effect (specific examples of insects transitioning between water and air). Choices B, C, and D are incorrect because they do not accurately describe the relationship between the two paragraphs as cause and effect.

3. To which section of the library should Jorgen go to learn more about the letters of the Greek alphabet and the meaning of the word 'beta'?

• A. 200
• B. 400
• C. 700
• D. 900

Correct answer: B

Rationale: Jorgen should go to section 400 in the library to learn more about the letters of the Greek alphabet and the meaning of the word 'beta.' Section 400 is dedicated to languages, making it the most suitable place to find information on alphabets. Choices A, C, and D are incorrect because Section 200 is about religion, Section 700 is about arts and recreation, and Section 900 is about history, geography, and biography, which are not relevant to Jorgen's search for information on the Greek alphabet.

4. Which of the answer choices gives the best definition of the underlined word in the following sentence? 'Finlay flatly refused to take part in the piano recital, so his parents had to cajole him with the promise of a trip to his favorite toy store.'

• A. Prevent
• B. Threaten
• C. Insist
• D. Coax

Correct answer: D

Rationale: In this context, 'cajole' means to persuade someone by using flattery or promises, which is best represented by 'coax.' 'Prevent' (choice A) means to stop something from happening, 'threaten' (choice B) means to communicate an intention to harm, and 'insist' (choice C) means to demand something forcefully, so these choices do not fit the context of persuading with flattery or promises.

5. Which of the following is the intricate network of blood vessels responsible for transporting blood throughout the body?

• A. Lymphatic system
• B. Circulatory system
• C. Nervous system
• D. Respiratory system

Correct answer: B

Rationale: The circulatory system, comprising the heart, blood vessels (arteries, veins, and capillaries), and blood, is responsible for transporting blood, oxygen, nutrients, and waste products throughout the body. The lymphatic system aids in maintaining fluid balance and fighting infections; the nervous system transmits signals. The respiratory system facilitates the exchange of oxygen and carbon dioxide in the body, which is distinct from the circulatory system's role in blood transport. Therefore, the correct answer is the Circulatory system (Choice B). Choices A, C, and D are incorrect as they do not pertain to the intricate network of blood vessels responsible for transporting blood throughout the body.
