Teacher guide & answers

In this lesson: Explain why major-flood resilience takes longer than some smaller-event benefits.

Restoration benefits need a time horizon

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 the roughly 20-year estimate concern?
Correct answer: C — New trees withstanding major floods
Why: The paragraph separates major-flood resilience from possible earlier benefits.
Clue in the story: Vegetated banks reduce erosion. Newly planted trees were estimated to need about 20 years to withstand major floods, although smaller events could see benefits earlier.
What information helps interpret an estimated return?
Correct answer: A — Its calculation and time horizon
Why: A meaningful estimate needs a defined measure and period.
Clue in the story: The important reading distinction is between estimated benefits and an immediate cash return. A percentage without a defined calculation and time horizon can mislead; this account does not promise investors a payout.

The open question: accept different answers

Ask learners: Why does the 20-year estimate not mean there are no earlier benefits?

One possible answer: The estimate concerns new trees withstanding major floods. The passage says smaller events could see benefits earlier, so the timescale depends on the type of benefit.

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

Concession with although

although smaller events could see benefits earlier

“Although” introduces a fact that contrasts with the main clause. Example: “Although the road was narrow, the bus passed.” Do not add “but” between the same clauses.
