In this lesson: Evaluate the scope of a global environmental conclusion.
Mangrove Recovery Is Global but Uneven
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 worksheetA 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.
Which timing claim follows from the first paragraph?
Correct answer: C — The feature reports observations from an earlier period
Why: The November 13 feature discusses Landsat observations spanning 1984–2023, rather than observations made only on its publication day.
Clue in the story: NASA’s November 13 feature highlights a reversal in mangrove trends identified in Landsat observations spanning 1984–2023. Global expansion began around 2010.
Why is universal recovery too strong a claim?
Correct answer: B — Some regions continued to lose forests
Why: The second paragraph preserves continuing regional losses.
Clue in the story: Both new colonisation and regeneration contributed. Nevertheless, continuing regional losses mean the global rebound cannot be interpreted as universal recovery.
The open question: accept different answers
Ask learners: Distinguish the global rebound from a claim about every region.
One possible answer: The observations identify global expansion beginning around 2010, with colonisation and regeneration contributing. Continuing regional losses mean this overall gain does not establish recovery in every region.
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
A conclusion despite a positive trend
Nevertheless
Nevertheless introduces a limitation that remains valid despite the preceding evidence of gains.
