Nursing Elites

1. 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.

2. Which of the following best describes the type of writing used in the email message sent by the instructor?

• A. technical
• B. narrative
• C. persuasive
• D. expository

Correct answer: C

Rationale: The email sent by the instructor after reconsidering his grading plan for the semester is aimed at persuading the students to understand the situation and potentially take certain actions based on his decision. It is not a technical piece that focuses on explaining complex processes, nor is it primarily a narrative recounting events. It also does not strictly provide information or explain a topic (expository writing). Instead, the email's purpose is to influence the students' perspective or behavior, making it a persuasive type of writing.

3. Which of the following is true of hypotheses of the form 'All x are y'?

• A. Something that is neither x nor y disproves the hypothesis.
• B. Something that is both x and y disproves the hypothesis.
• C. Something that is x but not y disproves the hypothesis.
• D. Something that is y but not x disproves the hypothesis.

Correct answer: D

Rationale: In hypotheses of the form 'All x are y,' the hypothesis is making a claim that all instances of x also fall under y. Therefore, if something is y but not x, it disproves the hypothesis because it contradicts the assertion that all x are y. Choice A is incorrect because something that is neither x nor y doesn't provide evidence against the hypothesis. Choice B is incorrect because if something is both x and y, it actually supports the hypothesis. Choice C is incorrect as something that is x but not y doesn't disprove the hypothesis, as it could still be consistent with the claim that all x are y.

4. In a lesson on mass media, a teacher is showing commercials and analyzing their hidden messages. Which of the following is an example of a commercial that claims professional authority not supported by evidence?

• A. A commercial selling pain relief featuring a professional basketball player who says he uses the product
• B. A commercial for cold medicine narrated by a man in a doctor's coat
• C. A commercial for a new toy showing footage of children playing happily with it
• D. A commercial for a prepared food with testimonials by real consumers

Correct answer: B

Rationale: The commercial for cold medicine narrated by a man in a doctor's coat is the correct answer. This commercial claims professional authority without providing any evidence of the narrator's credentials. While the man may appear to be a doctor with his coat, there is no proof that he is actually a medical professional or that the product is recommended by experts. This lack of evidence can mislead consumers by giving the product an air of legitimacy and credibility without factual support. Choices A, C, and D do not fit the criteria as they involve a professional athlete endorsing a product, children enjoying a toy, and real consumers providing testimonials respectively.

5. How did Hedy Lamarr contribute significantly to the advancement of technology?

• A. The technology of the era wasn't advanced enough to easily implement Lamarr's system
• B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon
• C. She had several failed inventions, such as an improved traffic light and a carbonated drink
• D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

Correct answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.
