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.

4. What is the meaning of the phrase 'phased in' as it is used in the third paragraph?

Correct answer: C

Rationale: 'Phased in' means implemented in stages, referring to the gradual implementation of good manufacturing practices. In the provided extract, it mentions that requirements for good manufacturing practices (GMPs) were phased in for small manufacturers through 2010, indicating a gradual implementation process. The other choices, 'stunned into silence,' 'confused,' and 'legalized,' do not accurately reflect the meaning of 'phased in' in the context of the paragraph.
