1. Which neuromuscular system controls voluntary movement?

A. Autonomic
B. Somatic
C. Sympathetic
D. Parasympathetic

Correct answer: B

Rationale: The correct answer is B, Somatic. The somatic nervous system controls voluntary movements of skeletal muscles. It is responsible for carrying sensory and motor information to and from the central nervous system. Choices A, C, and D are incorrect. The autonomic nervous system (choice A) controls involuntary functions such as heart rate and digestion. The sympathetic (choice C) and parasympathetic (choice D) nervous systems are subdivisions of the autonomic nervous system and are responsible for the body's fight-or-flight response and rest-and-digest functions, respectively.

2. 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.

3. Where does sperm production occur?

A. Prostate gland
B. Seminal vesicles
C. Scrotum
D. Seminiferous tubules

Correct answer: D

Rationale: Sperm production occurs in the seminiferous tubules within the testes. These tubules are responsible for spermatogenesis, the process of sperm creation. The prostate gland and seminal vesicles contribute to seminal fluid production, while the scrotum houses the testes but does not produce sperm. Therefore, choices A, B, and C are incorrect as they are not sites for sperm production.

4. 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.

5. How does the author generally present the information in the extract?

A. Chronological order
B. Comparison-contrast
C. Cause-effect
D. Conclusion-premises

Correct answer: C

Rationale: The author generally presents the information in a cause-effect format. The scientist talks about the increase in carbon dioxide emissions by countries like China, India, and Brazil leading to rising global temperatures. The politician, on the other hand, argues against a causal link between carbon emissions and temperature increase, suggesting a natural rise in temperatures. The information is structured around the cause of carbon emissions and its effect on global temperatures. Choice A, chronological order, is incorrect as the information is not presented in a time sequence but rather based on cause and effect. Choice B, comparison-contrast, is not the best description as the focus is more on cause and effect rather than comparing or contrasting different elements. Choice D, conclusion-premises, is also incorrect as the information does not follow the pattern of drawing conclusions based on premises but rather discusses the relationship between carbon emissions and temperature increase.
