1. Which of the following words is hyphenated correctly?

A. Ex-president
B. Hyperactive
C. Self-made
D. Mid-America

Correct answer: D

Rationale: The correct answer is 'Mid-America.' It is correctly hyphenated as it combines 'Mid' and 'America' to form a compound noun. Choice A, 'Ex-president,' should be hyphenated to show the prefix 'Ex-' before 'president.' Choice B, 'Hyperactive,' should not be hyphenated as 'hyper' is a prefix. Choice C, 'Self-made,' should be hyphenated to connect 'self' and 'made' in this compound adjective.

2. Which of the following touch receptors respond to light touch and slower vibrations?

A. Merkel's discs
B. Pacinian corpuscles
C. Meissner's corpuscles
D. Ruffini endings

Correct answer: A

Rationale: The correct answer is A, Merkel's discs. Merkel's discs are touch receptors that respond to light touch and slower vibrations, making them ideal for detecting subtle tactile stimuli. Pacinian corpuscles are specialized in detecting deep pressure and high-frequency vibrations, not light touch or slower vibrations. Meissner's corpuscles, on the other hand, are sensitive to light touch and low-frequency vibrations, but they do not specifically respond to slower vibrations. Ruffini endings are responsible for detecting skin stretch and continuous touch pressure, differentiating them from Merkel's discs, which are specifically attuned to light touch and slower vibrations.

3. How does an increase in mass affect the force required to produce the same acceleration on an object?

A. Increases force required
B. Decreases force required
C. Has no effect on force required
D. Causes unpredictable changes in force required

Correct answer: A

Rationale: The correct answer is A, 'Increases force required.' According to Newton's second law of motion, force is directly proportional to mass and acceleration (F = ma). Therefore, an increase in mass will require an increase in force to produce the same acceleration on an object. Choice B is incorrect because an increase in mass does not decrease the force required; it increases it. Choice C is incorrect as increasing mass does affect the force required. Choice D is incorrect as the relationship between mass and force is predictable according to Newton's laws of motion.

4. What is the most effective way to combine the two sentences below?

A. German cuisine is known for its hearty meat and potato dishes but families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
B. German cuisine is known for its hearty meat and potato dishes, but families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
C. German cuisine is known for its hearty meat and potato dishes and families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.
D. German cuisine is known for its hearty meat and potato dishes, and families often enjoy a rich Sunday dinner of roast meat, potatoes, and cabbage.

Correct answer: D

Rationale: The correct answer is D. This choice effectively combines the two sentences with the use of a comma before 'and' to connect the two related but independent clauses. The comma helps to separate the contrasting information about German cuisine and the Sunday dinner, maintaining a clear and coherent structure. Choices A, B, and C are incorrect because they either lack the necessary punctuation or use 'but' instead of 'and,' which disrupts the flow of the combined sentence and fails to convey the intended relationship between the two ideas.

5. The SI prefixes micro and milli represent, respectively:

A. 10^-6 and 10^-3
B. 10^-9 and 10^-6
C. 10^-12 and 10^-9
D. 10^-15 and 10^-12

Correct answer: A

Rationale: The prefixes 'micro-' and 'milli-' represent 10^-6 and 10^-3, respectively. 'Micro-' denotes one-millionth (10^-6), while 'milli-' denotes one-thousandth (10^-3). Choice B is incorrect because it confuses the order of magnitudes for micro and milli. Choice C and D are also incorrect as they provide the wrong values for the prefixes micro and milli.
