1. In fluid machinery, pumps are designed to primarily increase the fluid's:

• A. Pressure
• B. Velocity only
• C. Both pressure and velocity
• D. Neither pressure nor velocity

Correct answer: A

Rationale: Pumps in fluid machinery are designed to primarily increase the fluid's pressure. This increase in pressure allows the fluid to flow through the system efficiently and overcome resistance. While pumps can also impact the velocity of the fluid to some extent, their main function is to elevate the pressure to facilitate the movement of the fluid within the system. Choice B is incorrect because pumps do not focus solely on increasing velocity. Choice C is incorrect as while pumps can affect velocity, their primary purpose is to boost pressure. Choice D is incorrect as pumps aim to increase either the pressure, velocity, or both.

2. Select the word that makes the following sentence grammatically correct. The intern had to select _________ three specialties.

• A. among
• B. between
• C. with
• D. along

Correct answer: A

Rationale: The correct answer is A, 'among'. When choosing from more than two items, the preposition 'among' is used. In this case, 'among' is the appropriate choice as the intern had to select from three specialties, indicating a selection from a group rather than a choice between two specific options. Choice B, 'between', is incorrect because it is used when choosing between two items. Choice C, 'with', and choice D, 'along', are also incorrect as they do not convey the idea of choosing from a group of items.

3. Select the meaning of the word 'initial' in the sentence: 'The doctor made an initial examination of the patient.'

• A. Complete
• B. First
• C. Incomplete
• D. Discharge

Correct answer: B

Rationale: In this context, 'initial' means 'first,' referring to the first examination conducted by the doctor. The initial examination is the first assessment or evaluation performed on the patient. Therefore, 'first' is the correct meaning in this sentence. 'Complete' (choice A) is incorrect as initial does not imply completeness, 'incomplete' (choice C) is incorrect as initial does not mean unfinished, and 'discharge' (choice D) is unrelated to the concept of an initial examination.

4. How many feet are in 6 meters?

• A. 1.83 feet
• B. 18.48 feet
• C. 18.8 feet
• D. 19.68 feet

Correct answer: D

Rationale: To convert meters to feet, you can use the conversion factor: 1 meter = 3.28084 feet. Therefore, for 6 meters: 6 × 3.28084 = 19.684 feet. Rounding to two decimal places, the answer is 19.68 feet. Choice D, 19.68 feet, is the correct conversion. Choice A, 1.83 feet, is incorrect as it seems to be a miscalculation. Choice B, 18.48 feet, is incorrect as it doesn't match the correct conversion. Choice C, 18.8 feet, is also incorrect as it is not the accurate conversion from 6 meters to feet.

5. What charge do Group VA elements typically have?

• A. -1
• B. -2
• C. -3
• D. 0

Correct answer: C

Rationale: Group VA elements, also known as Group 15 elements, typically have a charge of -3. This is because they have five valence electrons and tend to gain three electrons to achieve a stable octet configuration, resulting in a -3 charge. Choice A (-1) and Choice B (-2) are incorrect because Group VA elements need to gain three electrons to reach a stable electron configuration, not just one or two. Choice D (0) is also incorrect because Group VA elements do not lose electrons to form a charge of 0.
