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 implicitly assumes that there is a lack of public awareness or association between the Department of Energy and algae research, which may influence perceptions regarding the viability of hydrogen-producing algae as an energy source. This assumption is crucial for understanding the context in which the author discusses the topic.

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

This assumption is not made by the author. The passage does not discuss the cost comparison of gases produced by algae versus other sources. Instead, it focuses on the relationship between public perception and the association of algae research with the Department of Energy.

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

The passage does not provide any information or evidence that the Department of Energy is currently using hydrogen-producing algae. The author discusses the potential for algae research but does not claim that it is already being implemented as a source of energy.

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

The author does not make any claims regarding the capabilities of mutant algae in photosynthesis. This option introduces a new concept that is not relevant to the main argument about public perception and the association with the Department of Energy.

Conclusion

The author’s assumption highlights a gap in public awareness regarding the Department of Energy's involvement in algae research, which is critical for understanding the broader implications for the acceptance and promotion of hydrogen-producing algae as a clean energy source. By recognizing this assumption, readers can better appreciate the challenges faced in advancing algae research within the energy sector.
