Read the passage(s) below and answer the question on the basis of what is stated or implied in the passage(s) and in any introductory material that may be provided.
Passage
During the process of photosynthesis, algae produce a small amount of hydrogen gas. Recently, microbiologists funded by the Department of Energy figured out how to create mutant versions of algae that generate much more hydrogen. You are probably wondering why the Department of Energy is funding this research. The answer is that the hydrogen produced by algae could one day be used to provide energy to entire cities.

What assumption does the author of the passage make?

Rationale

Readers do not associate the Department of Energy with algae research.

The author assumes that the general public lacks a connection between the Department of Energy and the research on algae, which influences the way the information is presented in the passage. This assumption helps frame the argument for the potential benefits of using algae in energy production.

A (Gases produced by algae will be cheaper to produce than other gases.) YOUR ANSWER

The author does not make a direct comparison of the costs associated with algae-produced gases versus other sources in the passage. This choice introduces a potential outcome rather than addressing the underlying assumptions about public perception or knowledge.

B (The Department of Energy is already using hydrogen-producing algae as a source of energy.) YOUR ANSWER

This option suggests a current state of affairs that is not addressed in the passage. The author does not assume that the Department of Energy is currently utilizing algae, but rather implies that there is a need to change perceptions about their involvement in algae research.

C (Mutant versions of algae will not be capable of the process of photosynthesis.) YOUR ANSWER

This statement reflects a specific biological assumption about algae that is not mentioned in the passage. The author's focus is on the association of the Department of Energy with algae research rather than the capabilities of mutant algae.

Conclusion

The passage relies on the assumption that readers do not typically associate the Department of Energy with algae research, shaping the narrative to address this misconception. By highlighting this disconnect, the author aims to advocate for further exploration and potential investment in algae as an energy source, while the other options either introduce unrelated concepts or misinterpret the assumptions made within the text.
