Select two details from paragraphs 3–6 that support the claim that robots are helpful in work environments.

3 Robotina has been in the interactive robotics lab of engineering professor Julie Shah since 2011, where it is one of three main robot platforms Shah’s team works with. Robotina is aptly named, as an aim is to give it many of Rosie's capabilities: to interact with humans and perform many types of work. . . .

4 “We focus on how robots can assist people in high-intensity situations, like manufacturing plants, search-and-rescue situations and even space exploration,” Shah said.

5 What Shah and her team are finding in their experiments is that humans often work better and feel more at ease when Robotina is calling the shots—that is, when it’s scheduling tasks. In fact, a recent MIT experiment showed that a decision-making robotic helper can make humans significantly more productive.

6 Part of the reason for this seems to be that people not only trust Robotina’s impeccable ability to crunch numbers, they also believe the robot trusts and understands them.
