问题 This passage is mainly about the development and safety of robots.
Mr. Angle says a heterogeneous swarm of robots will take care of the house instead of ______.

选项

答案a humanoid robot maid

解析 全文最后一段最后一句:Rather than a humanoid robot maid,"it’s going to be a heterogeneous swarm of robots that will take care of the house," he says.空白处需要名词或名词词组,作instead of复合介词的宾语。原文中的rather than与题目中的instead of一样表示否定,因此答案为rather than之后的a humanoid robot maid。
