Read and understand · 1/2How did the response extend the laptop warning?

Read the answer and explanation

The robot avoided electronics more generally. The second paragraph describes a broader electronics category.

Clue: In a coffee task, a warning about a laptop helped the robot avoid electronics more generally. The demonstrations were simulations rather than tests in homes.

Read and understand · 2/2Which detail limits the demonstrations?

Read the answer and explanation

They used virtual arms rather than home tests. Both paragraphs describe virtual demonstrations and simulations.

Clue: In a coffee task, a warning about a laptop helped the robot avoid electronics more generally. The demonstrations were simulations rather than tests in homes.

Grammar in this story: Contrast with rather than

simulations rather than tests in homes

Rather than distinguishes the setting actually tested from a setting the report does not claim to have tested.

Your turn

Explain the broader response and its experimental limit.

See one possible answer

A warning about a laptop helped the virtual arm avoid electronics more generally. The work was demonstrated in simulations, so it does not show how the system performs in homes.
