1. Select the correct word for the blank in the sentence: 'After completing the intense surgery, Dr. Capra needed a long ____.'

• A. brake
• B. break
• C. brink
• D. broke

Correct answer: B

Rationale: The correct word to fill in the blank is 'break.' In this context, 'break' refers to a pause or rest, which is what Dr. Capra needed after completing the intense surgery. 'Brake' (choice A) refers to a device used to slow or stop a vehicle. 'Brink' (choice C) means the edge or verge of something. 'Broke' (choice D) is the past tense of 'break' and is grammatically incorrect in this sentence.

2. A gross is equal to 12 dozen. If Lanyard Farms sells 15 gross of eggs a week and packages them in one dozen egg containers, how many containers do they need for a week’s worth of eggs?

• A. 15
• B. 150
• C. 180
• D. 2,160

Correct answer: C

Rationale: Given that a gross is equal to 12 dozen, 15 gross of eggs would be equal to 15 * 12 = 180 dozen eggs. Since the eggs are packaged in one dozen egg containers, Lanyard Farms would need 180 containers for a week's worth of eggs. Choice A (15) is incorrect as it represents the number of gross, not containers. Choice B (150) is incorrect as it miscalculates the total number of containers needed. Choice D (2,160) is incorrect as it overestimates the number of containers required.

3. What is the function of the pituitary gland?

• A. Regulating metabolism
• B. Producing bile
• C. Filtering blood
• D. Controlling muscle movement

Correct answer: A

Rationale: The pituitary gland, known as the 'master gland,' plays a crucial role in regulating various physiological processes by secreting hormones that control other endocrine glands. This includes the regulation of metabolism, growth, reproduction, stress response, and more. Therefore, the correct function of the pituitary gland is regulating metabolism, making choice A the correct answer. Choices B, C, and D are incorrect as the pituitary gland is not involved in producing bile, filtering blood, or controlling muscle movement.

4. What is the primary function of the lymphatic system?

• A. Transport oxygen to cells
• B. Remove carbon dioxide from the body
• C. Produce hormones
• D. Transport nutrients

Correct answer: B

Rationale: The correct answer is B: Remove carbon dioxide from the body. The primary function of the lymphatic system is to return excess tissue fluid to the bloodstream and assist in the body's defense against infections by filtering out harmful pathogens and foreign particles. Choices A, C, and D are incorrect because transporting oxygen to cells is mainly done by the circulatory system, hormone production is primarily carried out by endocrine glands, and nutrient transport is also a function of the circulatory system and the digestive system, not the lymphatic system.

5. What is the name of the compound CH₃-CH₂-CH₂-CH₃?

• A. Cyclobutane
• B. Butane
• C. Butene
• D. Butyne

Correct answer: B

Rationale: The compound CH₃-CH₂-CH₂-CH₃ is named butane. Butane is a straight-chain alkane comprising four carbon atoms connected by single bonds. The prefix 'but-' denotes the presence of four carbon atoms, while the suffix '-ane' indicates it is an alkane with single bonds between the carbon atoms. Choice A, Cyclobutane, is incorrect as it refers to a cyclic hydrocarbon with four carbon atoms in a ring structure. Choice C, Butene, is incorrect because it is an alkene with a double bond between two carbon atoms, not a saturated hydrocarbon like butane. Choice D, Butyne, is also incorrect as it is an alkyne with a triple bond between two carbon atoms, unlike the single bonds in butane.
