Question 15

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

The author assumes that the general public may not connect the Department of Energy with research on algae, particularly in the context of hydrogen production. This assumption underlies the rationale for the funding and the innovative research being discussed.

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

This option is incorrect because the passage does not provide any information or implication regarding the cost-effectiveness of gases produced by algae compared to other sources. The focus is on the potential energy benefits rather than economic comparisons.

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

This option is also incorrect. The passage discusses ongoing research funded by the Department of Energy but does not suggest that they are currently using hydrogen-producing algae as an energy source. It implies future potential rather than present application.

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

This choice is incorrect as the passage states that mutant versions of algae can generate more hydrogen, which implies they are capable of photosynthesis. The assumption that they would not be capable contradicts the information presented.

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

This is the correct assumption made by the author. The passage hints at a disconnect between the Department of Energy's role and current public perception regarding their involvement in algae research, thereby highlighting a need for awareness about the innovative research being conducted.

Conclusion

The assumption that readers do not associate the Department of Energy with algae research is central to the author's argument, as it helps to justify the funding and highlights the novelty of the research. All other options fail to align with the information provided in the passage, focusing instead on irrelevant aspects or misinterpretations of the data presented.
