1. Select the context clue from the following sentence that helps you define the word pungent: 'The pungent odor in the room made everyone’s eyes tear for a few minutes.'

• A. odor
• B. room
• C. made
• D. tear

Correct answer: A

Rationale: The correct answer is 'A: odor.' In the sentence provided, 'odor' serves as the context clue that helps define 'pungent' as a strong smell. The word 'pungent' commonly refers to something having a sharply strong scent, and 'odor' directly relates to this meaning in the sentence. Choices 'B: room,' 'C: made,' and 'D: tear' do not provide contextual information about the meaning of 'pungent,' making them incorrect choices for defining the word in this context.

2. Where does the digestion of food start?

• A. Esophagus
• B. Stomach
• C. Small intestine
• D. Mouth

Correct answer: D

Rationale: The correct answer is the mouth. Digestion begins in the mouth where mechanical breakdown occurs through chewing, and chemical breakdown begins with saliva. Enzymes in saliva start breaking down carbohydrates, initiating the digestion process. The esophagus is responsible for transporting food from the mouth to the stomach and does not play a role in the digestion process. The stomach continues the digestion process after the food leaves the mouth. The small intestine is primarily responsible for absorbing nutrients from the digested food, rather than being the initial site of digestion.

3. Which of the following is the body cavity that contains the urinary bladder, urethra, and ureters?

• A. The thoracic cavity
• B. The pelvic cavity
• C. The abdominal cavity
• D. The spinal cavity

Correct answer: B

Rationale: The correct answer is B, the pelvic cavity. The pelvic cavity houses organs related to the urinary and reproductive systems. The urinary bladder, urethra, and ureters are located in the pelvic cavity, making it the correct choice. The thoracic cavity contains the heart and lungs, while the abdominal cavity houses organs like the stomach and intestines. The spinal cavity, on the other hand, protects the spinal cord. Therefore, options A, C, and D are incorrect as they do not house the specific organs mentioned in the question.

4. What is the word 'principal' referring to in the following text?

• A. Primary or chief
• B. An acolyte
• C. An individual who provides nurturing
• D. One in a subordinate position

Correct answer: A

Rationale: In the provided text, 'principal' is referring to the primary or chief individual. The principal secretary for private affairs is considered second only to the treasurer, indicating a position of high importance. The term 'acolyte' (Choice B) refers to a ceremonial assistant, which does not fit the context. 'An individual who provides nurturing' (Choice C) and 'One in a subordinate position' (Choice D) do not accurately describe the role of the 'principal' in the text.

5. What is the correct way to represent 8,600,000,000,000 in scientific notation with two significant figures?

• A. 8.6 x 10^12
• B. 8.6 x 10^-12
• C. 8.6 x 10^11
• D. 8.60 x 10^12

Correct answer: A

Rationale: The correct way to represent 8,600,000,000,000 in scientific notation with two significant figures is 8.6 x 10^12. Scientific notation involves expressing a number as a decimal (with one non-zero digit before the decimal point) multiplied by a power of 10. In this case, 8,600,000,000,000 is correctly written as 8.6 x 10^12 to maintain two significant figures and the appropriate magnitude. Choice B (8.6 x 10^-12) is incorrect as it represents a very small number due to the negative exponent. Choice C (8.6 x 10^11) is incorrect as it does not account for the magnitude of the original number. Choice D (8.60 x 10^12) is incorrect because it unnecessarily adds a zero after the decimal point, which is not warranted by the original number's precision.
