1. Based on the evidence found, electrical stimulation may be a potential therapy for OSAS, warranting further clinical trial. Which type of document is this sentence most likely from?

• A. Motivational speech
• B. Business memo
• C. Scientific journal article
• D. Personal blog

Correct answer: C

Rationale: The sentence discusses evidence and clinical trials related to a specific therapy, indicating a scientific context. Scientific journal articles are known for presenting research findings, discussing evidence, and proposing further studies, making them the most suitable source for this type of information. Choices A, B, and D are incorrect because a motivational speech is more focused on inspiring and encouraging, a business memo typically deals with internal communication in organizations, and a personal blog reflects individual opinions or experiences, none of which align with the content and tone of the sentence provided.

2. What is the GCF (greatest common factor)?

• A. The largest factor that all the numbers share
• B. The smallest factor that all the numbers share
• C. The largest multiple that all the numbers share
• D. The smallest multiple that all the numbers share

Correct answer: A

Rationale: The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. This factor represents the highest number that can evenly divide each of the numbers in the set without any remainder. Choice B, 'The smallest factor that all the numbers share,' is incorrect because the GCF is the greatest, not the smallest, factor. Choices C and D, 'The largest multiple that all the numbers share' and 'The smallest multiple that all the numbers share,' are also incorrect as the GCF refers to factors, not multiples.

3. What is the significance of the term 'Bunburying' in the context of the play?

• A. It highlights the characters' desire to lead a double life and escape social obligations.
• B. It reflects the characters' indifference to social conventions.
• C. It demonstrates the characters' willingness to deceive themselves and others.
• D. It serves as a metaphor for the characters' struggle to conform to societal expectations.

Correct answer: A

Rationale: 'Bunburying' is significant in the play because it emphasizes the characters' desire to lead double lives and avoid the strict societal expectations placed upon them. The term highlights their need to escape the confines of social obligations through deception and subterfuge. By maintaining a fictional persona like Bunbury, the characters can freely navigate between different social spheres, allowing them to explore personal freedom and evade the constraints of their social status. This escapade showcases their yearning for independence and autonomy, contrasting with the societal norms they are expected to conform to. Choices B, C, and D are incorrect because 'Bunburying' in the context of the play is more about evading social duties through a dual identity, rather than reflecting indifference, willingness to deceive, or struggling to meet societal expectations.

4. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength remains the same
• D. Wavelength becomes zero

Correct answer: B

Rationale: When the speed of a wave is constant and the frequency increases, the wavelength must decrease to keep the speed constant. The speed of a wave is determined by the product of frequency and wavelength (speed = frequency x wavelength). If the frequency increases while the speed remains constant, the wavelength has to decrease proportionally to maintain the speed unchanged. Therefore, as the frequency increases, the wavelength decreases to ensure that the speed of the wave remains constant. Choice A is incorrect because as frequency increases, wavelength decreases. Choice C is incorrect as the wavelength cannot remain the same when frequency increases while speed is constant. Choice D is incorrect as the wavelength cannot become zero under these conditions.

5. Which of the following sentences is punctuated correctly?

• A. A carpenter must use certain tools - hammers, saws, chisels - to finish a job.
• B. A carpenter must use certain tools: hammers, saws, chisels to finish a job.
• C. A carpenter must use certain tools hammers, saws, chisels to finish a job.
• D. A carpenter must use certain tools; hammers, saws, chisels to finish a job.

Correct answer: A

Rationale: Choice A is the correct answer as the sentence is correctly punctuated using em dashes to set off the list. The em dashes help to clearly separate the list of tools from the rest of the sentence. In Choice B, a colon is used, which is incorrect as colons are typically used to introduce a list, not within the list itself. Choice C lacks any punctuation to separate the list, making it unclear and incorrect. Choice D uses semicolons, which are not appropriate for separating items in a list, making it incorrect as well.
