1. Which form of fermentation is used to produce beer?

• A. Lactic acid fermentation
• B. Acetic acid fermentation
• C. Propionic acid fermentation
• D. Ethyl alcohol fermentation

Correct answer: D

Rationale: The correct answer is D, Ethyl alcohol fermentation. During beer production, yeast metabolizes sugars in the wort to produce ethanol (ethyl alcohol) and carbon dioxide, which are responsible for the alcohol content and carbonation in beer. Choices A, B, and C are incorrect because lactic acid fermentation produces lactic acid, acetic acid fermentation produces acetic acid, and propionic acid fermentation produces propionic acid, none of which are used in the production of beer.

2. Choose the meaning of the word quandary in the following sentence: 'Too many potential job choices put Martin in a quandary.'

• A. A place where rocks are mined
• B. A journey of discovery
• C. A state of uncertainty
• D. A major attempt or trial

Correct answer: C

Rationale: In this context, the word 'quandary' refers to a state of uncertainty or confusion caused by being faced with a difficult decision or choice. This matches the meaning of option C. Choices A, B, and D are incorrect because 'quandary' does not relate to a place where rocks are mined (A), a journey of discovery (B), or a major attempt or trial (D), but rather to a state of uncertainty or confusion.

3. What does 'overt' mean?

• A. Hidden
• B. Obvious or easily observed
• C. Barely noticeable
• D. Misleading

Correct answer: B

Rationale: The correct answer is B: 'Obvious or easily observed.' Overt means something that is not hidden or concealed but rather openly displayed or easily noticed. Choice A, 'Hidden,' is the opposite of overt. Choice C, 'Barely noticeable,' implies something not overt but rather subtle. Choice D, 'Misleading,' is unrelated to the definition of overt.

4. As the frequency of a sound wave increases, what else is true?

• A. Its wavelength decreases.
• B. Its wavelength increases.
• C. Its amplitude decreases.
• D. Its amplitude increases.

Correct answer: A

Rationale: The correct answer is A: 'Its wavelength decreases.' The frequency and wavelength of a sound wave are inversely proportional. As the frequency of a sound wave increases (more oscillations per second), its wavelength decreases. This relationship is described by the formula: Speed of Sound = Frequency x Wavelength. Therefore, to maintain the speed of sound constant, when the frequency increases, the wavelength must decrease. Choices B, C, and D are incorrect because an increase in frequency does not lead to an increase in wavelength or changes in amplitude.

5. The plumber used a tube to navigate through the curved pipe. What type of tube would be most suitable for this task?

• A. Solid
• B. Rigid
• C. Flexible
• D. Perforated

Correct answer: C

Rationale: A flexible tube would be appropriate for navigating through a curved pipe as it can bend and maneuver easily within the pipe's shape. This flexibility allows the plumber to access and address any blockages or issues efficiently. Solid and rigid tubes would be challenging to use in a curved pipe due to their lack of flexibility, making navigation difficult. Perforated tubes, with holes, are not typically used for this purpose and are more suited for specific applications like drainage systems.
