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.

What does ceiling mean here?
Correct answer: C — An upper investment limit
Why: Each ceiling limits the investment to $500 million.
Clue in the story: Reuters reported that TSMC’s board authorised separate investments in Anthropic and OpenAI on November 10. Each has a $500 million ceiling.
What cannot be established from the combined limit?
Correct answer: B — The amount ultimately spent
Why: The final sentence explicitly separates the upper limit from actual spending.
Clue in the story: The plans extend beyond manufacturing chips to holding stakes in AI developers. A combined upper limit of $1 billion does not establish the amount ultimately spent.

The open question: accept different answers

Ask learners: Write a careful financial summary.

One possible answer: TSMC authorised separate investments in Anthropic and OpenAI, each capped at $500 million. Their combined $1 billion ceiling does not reveal the amount eventually spent.

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.
