Swift Leaves an Archive After Operations End
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.
What operational limitation ended observations?
Correct answer: A — Drag prevents steady aim
Why: Maintaining telescope aim is no longer possible.
Clue in the story: Swift’s declining orbit has ended its observing mission: atmospheric drag now prevents the telescopes from maintaining steady aim, NASA reported on October 23.
Which sequence matches the text?
Correct answer: B — Final observation, announcement, expected re-entry
Why: October20 preceded the October23 report; re-entry is future.
Clue in the story: Its last observation occurred three days earlier. Atmospheric re-entry is expected within weeks, while its extensive public archive offers material for future discoveries.
The open question: accept different answers
Ask learners: Retell the chronology while distinguishing observation from forecast.
One possible answer: Observations ended before the announcement. Re-entry is expected later; archived data remains useful.
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.
