1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. What is the meaning of exacerbate?

A. To lessen in intensity
B. To make worse
C. To neutralize
D. To control

Correct answer: B

Rationale: The correct answer is B: 'To make worse.' Exacerbate means to worsen or make a situation, condition, or problem more severe or intense, not to lessen it. Therefore, if something exacerbates a situation, it means it makes it worse. Choices A, C, and D are incorrect because exacerbate does not mean to lessen in intensity, neutralize, or control the situation, but rather to worsen it.

3. Choose the meaning of the word 'riddled' in the following sentence: 'The cavity, once opened, proved to be riddled with infection.'

A. Challenged
B. Overrun
C. Separated
D. Complete

Correct answer: B

Rationale: The word 'riddled' in this context means filled with or affected by (something undesirable) to a great degree, which aligns with the definition of 'overrun.' In this sentence, the cavity is described as being full of infection, indicating that the infection has spread extensively throughout. 'Challenged' (choice A) implies being tested or provoked, which is not the meaning conveyed by 'riddled.' 'Separated' (choice C) means divided or isolated, which does not fit the context of the sentence. 'Complete' (choice D) means finished or whole, which is the opposite of what is described in the sentence where the cavity is full of infection.

4. Nurse Junko and _______ will review the patient’s chart.

A. She
B. Them
C. Me
D. Him

Correct answer: A

Rationale: The correct answer is 'A: She.' In this sentence, 'She' is the correct pronoun to use as the subject since it refers to Nurse Junko, who is one of the individuals performing the action. 'Them' (choice B), 'Me' (choice C), and 'Him' (choice D) are incorrect as they do not match the subject of the sentence, which is Nurse Junko.

5. If someone is disseminating information, what are they doing?

A. Withholding it
B. Broadcasting it
C. Destroying it
D. Complicating it

Correct answer: B

Rationale: When someone is disseminating information, they are spreading it widely or broadcasting it to reach a larger audience. Therefore, the correct answer is B: 'Broadcasting it.' This process involves sharing information to make it widely known and accessible. Choice A, 'Withholding it,' is incorrect as it means keeping information back rather than sharing it. Choice C, 'Destroying it,' is incorrect as it means to eliminate or get rid of the information, which is the opposite of disseminating. Choice D, 'Complicating it,' is incorrect as it means making something more complex or difficult to understand rather than spreading it.
