1. What is the mathematical expression for 'Twelve less than thrice a number'?

• A. 3x-12
• B. 12-3x
• C. 3-12x
• D. 12x-3

Correct answer: A

Rationale: The phrase 'thrice a number' translates to 3x, and 'twelve less than' means subtracting 12 from it. Therefore, the correct expression is 3x-12. Choice B, '12-3x', represents '12 less than a number thrice,' which is the opposite of the given phrase. Choice C, '3-12x', does not correctly interpret the phrase provided. Choice D, '12x-3', represents 'a number thrice less than twelve,' which is not the same as the original phrase.

2. Which of the following substitutions best captures the meaning of the word 'egregious' in the sentence: 'The errors were becoming so frequent and egregious that the company had no choice but to force the humbled administrator into early retirement'?

• A. thoughtless
• B. bizarre
• C. minor
• D. flagrant

Correct answer: A

Rationale: 'Egregious' means outstandingly bad or shocking. Among the given choices, 'thoughtless' is the best substitution that captures a similar meaning. This is because 'thoughtless' implies actions or errors committed without careful consideration, which aligns with the negative connotation of the word 'egregious' in the sentence. 'Bizarre' (choice B) means strange or unusual, not necessarily bad. 'Minor' (choice C) means of lesser importance or seriousness, which contrasts with the strong negativity of 'egregious.' 'Flagrant' (choice D) means obviously offensive or bad, but it does not fully capture the sense of shock and outstandingly bad conveyed by 'egregious.'

3. What properties distinguish laser light from typical light sources?

• A. Enhanced brightness only
• B. Monochromatic nature (single color) and coherence (synchronized waves)
• C. Increased velocity
• D. Limited visibility to the human eye

Correct answer: B

Rationale: Laser light differs from typical light sources due to its monochromatic nature (single color) and coherence (synchronized waves). This means that laser light consists of a single wavelength and synchronized waves, unlike typical light sources that emit a range of wavelengths and are incoherent. The monochromatic nature of laser light allows it to be of a single color, while coherence ensures that the waves are synchronized. These unique properties of laser light make it valuable for a wide range of applications in fields such as medicine, industry, and research. Choices A, C, and D are incorrect because laser light's distinguishing features are not related to enhanced brightness, increased velocity, or limited visibility to the human eye. Instead, it is the monochromatic nature and coherence that set laser light apart from typical light sources.

4. What is the best summary of this passage?

• A. Humans can use coloration and markings on snakes to determine whether they’re venomous.
• B. Animals use coloration to hide from predators.
• C. The scarlet kingsnake and the coral snake have nearly identical markings.
• D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.

Correct answer: A

Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.

5. It can be inferred from the advertisement that

• A. A person staffing this position may work independently and/or as part of a team.
• B. Veronica Davis will make the hiring decisions.
• C. Caseloads will start out small for new hires.
• D. A candidate could work part-time if he or she chooses to.

Correct answer: A

Rationale: It can be inferred from the advertisement that a person staffing this position may work independently and/or as part of a team. The job description mentions the requirement for the ability to work both self-directed and as part of a team, indicating flexibility in working styles. Choice B is incorrect as Veronica Smith is mentioned as the contact for application submission, not the hiring decision-maker. Choice C is incorrect as there is no mention of caseload sizes for new hires. Choice D is incorrect as the advertisement does not specify part-time work as an option.
