B. To be uniquely discovered

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.

C. Vanilla worked better than lemon for stress.
D. The study took place at Ohio State University.

Correct answer: C

Rationale: The passage does not support the idea that vanilla worked better than lemon for stress relief; instead, it focuses specifically on lemon and lavender as the tested scents. The absence of this information regarding vanilla makes C the correct answer, as it is not included in the details provided in the passage.

5. What is the meaning of the word 'enlist' as it is used in the second paragraph?

A. call into service
B. write down
C. send away
D. put across

Correct answer: A

Rationale: In the context of the immune system, 'enlist' means to call into service. Immune cells recruit other cells to fight infection by producing chemicals that regulate their growth, behavior, and direct new recruits to trouble spots. This process is essential for the immune system's defense mechanism. The other choices are incorrect: 'write down' and 'put across' do not capture the action of mobilizing immune cells, and 'send away' is opposite in meaning to what is happening in the immune response.
