Explanation:

Analyze the question requirements

The question asks for two details providing the best evidence that the Oas recirculating shower works more effectively (performance/cleanliness) and is more environmentally friendly (energy/water savings) than traditional showers.

Evaluate the options against the criteria

• Option 1: "And because the reused water is already warm, it takes minimal energy to heat it back to the target temperature." (paragraph 12) -> Directly supports "more environmentally friendly" (energy efficiency).
• Option 2: "The company has sold several thousand units..." (paragraph 15) -> Shows commercial success, not effectiveness or eco-friendliness.
• Option 3: "A material invented by Argonide Corporation..." (paragraph 9) -> Discusses a material's filtration capability, but is not specific to the Oas shower's overall comparative effectiveness and eco-friendliness.
• Option 4: "In the longer term, he wants to enable an entire habitat..." (paragraph 15) -> Discusses future goals, not current evidence of the shower's performance.
• Option 5: "The Swedish Institute for Communicable Disease Control has verified that the recycled water is cleaner than tap water." (paragraph 11) -> Directly supports "works more effectively" (cleanliness/purification performance).

Select the two best options

The two options that directly address both effectiveness (cleaner water than tap water) and environmental friendliness (minimal energy to heat) are Option 1 and Option 5.

Answer:

• "And because the reused water is already warm, it takes minimal energy to heat it back to the target temperature." (paragraph 12) (Correct answer)
• "The company has sold several thousand units, so far mostly to hotel chains and real estate developers, and the showers are becoming available to individual consumers..." (paragraph 15)
• "A material invented by Argonide Corporation, however, made up of positively charged microscopic alumina fibers, can remove virtually all contaminants..." (paragraph 9)
• "In the longer term, he wants to enable an entire habitat that runs on closed loops, recycling as much and using as little water as possible..." (paragraph 15)
• "The Swedish Institute for Communicable Disease Control has verified that the recycled water is cleaner than tap water." (paragraph 11) (Correct answer)
