Question

6 the use of exoskeletons extends into the field of medicine. some people who have paralysis or other conditions that impede their ability to move unaided use exoskeletons to help them with walking. although exoskeletons are not yet widely used for this purpose, scientists and engineers see promising signs ahead.
7 robots can be helpful in people’s homes too. these small robots function and interact with people in a variety of ways. home robots can be programmed to clean floors or do other minor tasks. some robots can even speak and answer questions as they perform these tasks around the home. there is almost no limit to the services these pint - size robots can offer.
8 most of the robots people use in their homes do not resemble living creatures. robotics companies have discovered that robots that look too human or lifelike make people uncomfortable. robotic pets are the exception. many look like the real thing, even though they cannot give the same affection that live pets do. but these robots do offer some real benefits. robotic cats and dogs can provide companionship for people living alone. and studies show that owning a robotic dog that looks and behaves like a real dog can ease

1. how does the author’s use of language in paragraphs 6 and 7 contribute to the mood of the article? select two correct answers.

• by taking a cautious approach to using robots in certain fields of work
• by hinting that patience is required while waiting for new types of robot technology
• by expressing excitement about the ways robots may help people in the future
• by indicating hope that people will one day fully embrace assistance from robots

Explanation:

1. Analyze Option 1: "By taking a cautious approach to using robots in certain fields of work" – Paragraphs 6 and 7 focus on the helpfulness and potential of exoskeletons and home robots, not caution in using robots. Eliminate this.
2. Analyze Option 2: "By hinting that patience is required while waiting for new types of robot technology" – The paragraphs talk about current uses and promising signs/few limits, not about needing patience for new tech. Eliminate this.
3. Analyze Option 3: "By expressing excitement about the ways robots may help people in the future" – Paragraph 6 says "scientists and engineers see promising signs ahead" and Paragraph 7 says "there is almost no limit to the services these pint - size robots can offer", showing excitement about future help. This is correct.
4. Analyze Option 4: "By indicating hope that people will one day fully embrace assistance from robots" – Paragraph 6's "promising signs" and Paragraph 7's wide - ranging service potential imply hope for full embrace of robot assistance. This is correct.

Answer:

C. By expressing excitement about the ways robots may help people in the future, D. By indicating hope that people will one day fully embrace assistance from robots
