1. A recipe calls for 2.5 teaspoons of vanilla. 1 teaspoon equals approximately 4.93 mL. Which of the following is the correct amount of vanilla in mL?
- A. 5.33 mL
- B. 7.43 mL
- C. 12.325 mL
- D. 0.507 mL
Correct answer: C
Rationale: To convert 2.5 teaspoons of vanilla to milliliters, you multiply by the conversion factor: 2.5 teaspoons * 4.93 mL = 12.325 mL. Therefore, the correct amount of vanilla in milliliters is 12.325 mL. Choice A (5.33 mL) is incorrect because it does not account for the correct conversion factor. Choice B (7.43 mL) is incorrect as it also does not use the accurate conversion factor. Choice D (0.507 mL) is incorrect as it represents a miscalculation of the conversion.
2. When Sofia went in for her yearly check-up, her doctor suggested that they do a blood test to get an update on her hypokalemia, since its decreasing levels were worrisome in the past.
- A. Better
- B. Above
- C. Too much
- D. Not enough
Correct answer: D
Rationale: The correct answer is 'Not enough.' The prefix 'hypo-' means 'under' or 'not enough,' as seen in the word 'hypokalemia,' which refers to low levels of potassium. 'Better' (choice A), 'Above' (choice B), and 'Too much' (choice C) are all incorrect because they do not convey the meaning of insufficient or low levels associated with hypokalemia.
3. If m represents a car’s average mileage in miles per gallon, p represents the price of gas in dollars per gallon, and d represents a distance in miles, which of the following algebraic equations represents the cost, c, of gas per mile?
- A. c = dp/m
- B. c = p/m
- C. c = mp/d
- D. c = m/p
Correct answer: B
Rationale: The cost of gas per mile, c, is calculated by dividing the price of gas, represented by p, by the car's average mileage, represented by m. Therefore, the correct equation is c = p/m. Choice A (dp/m) incorrectly multiplies the price of gas and distance, while choice C (mp/d) incorrectly multiplies the average mileage and price of gas. Choice D (m/p) incorrectly divides the average mileage by the price of gas, which does not represent the cost of gas per mile.
4. What verb tense is used in the underlined words in the following sentence? 'The doctor prescribed medicine after my son had been sick for four days.'
- A. Past perfect
- B. Present perfect
- C. Past progressive
- D. Present progressive
Correct answer: A
Rationale: The correct answer is 'A: Past perfect.' In the sentence, 'had been sick' is in the past perfect tense. The past perfect tense is formed with 'had' + the past participle of the main verb. In this sentence, it indicates an action that was completed before another past action. Choices B, C, and D are incorrect because the sentence does not contain the present perfect, past progressive, or present progressive tenses as indicated by the underlined words. The present perfect tense would require 'has' or 'have' + past participle, the past progressive would involve 'was' or 'were' + present participle, and the present progressive would include 'am', 'is', or 'are' + present participle, none of which are present in the sentence.
5. Which of the following is best identified as a hypothesis?
- A. The environmental temperature can affect the growth of a plant's root.
- B. Plants need light to grow.
- C. A colder environment produces longer roots.
- D. Plants need 60 days to grow their roots.
Correct answer: A
Rationale: Choice A is the best example of a hypothesis as it presents a testable statement regarding the impact of environmental temperature on plant root growth. A hypothesis should be specific and capable of being tested through experimentation, which is demonstrated in choice A. Choice B is a general statement rather than a testable hypothesis. Choice C lacks specificity and does not clearly state a cause-and-effect relationship to be tested. Choice D provides a specific time frame but does not address a relationship that can be tested through experimentation, making it less suitable as a hypothesis compared to choice A.
