FLEX Extends a Warning Beyond One Object

How to use these two pages

Give learners the student worksheet. It contains the story and questions, without the answers. Keep this guide for yourself. Use it to lead the activity and explain the answers afterwards.

Student worksheet

A simple 15–20-minute lesson

Before reading · 2 minutes
Show the title. Ask: “What do you think this story is about?”
Read and answer · 8–10 minutes
Give out the student worksheet. Learners read for the main idea, then reread to answer the 2 questions. They can compare answers with a partner.
Discuss and write · 5–8 minutes
Check the answers below together. Ask learners to point to the clue in the story, then finish with the open question.

Adjust the support: Let learners use word help or Level 1 if needed. For a challenge, compare the wording in another level. This activity is not a proficiency test.

Answers to the 2 questions

The question numbers match the student worksheet. Each answer includes a reason and the clue learners can find in the story.

How did the response extend the laptop warning?
Correct answer: A — The robot avoided electronics more generally
Why: The second paragraph describes a broader electronics category.
Clue in the story: 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.
Which detail limits the demonstrations?
Correct answer: C — They used virtual arms rather than home tests
Why: Both paragraphs describe virtual demonstrations and simulations.
Clue in the story: 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.

The open question: accept different answers

Ask learners: Explain the broader response and its experimental limit.

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.

This is an example, not the only correct answer. Look for a relevant idea, a reason and the learner’s own words. Learners can answer aloud or write one or two sentences.

Grammar to discuss

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.
