Before you read: identify the kind of evidence
The main trap in this lesson is a change of meaning between “first recorded” and “first actual”. Mark those expressions before answering. A notebook records encounters; it does not automatically describe everything that happened when observers were absent. Keep the historical records, the later checks and the future plan separate in your notes.
This is original IELTS-style practice with a short, fictional learning scenario. It is not a Cambridge passage or an answer key to any named published test. Paragraph A supplies a brief factual introduction; paragraphs B–E describe invented people, materials and events. Answer from this passage alone. You do not need to research the topic or agree with a character to identify what the text says.
Read once for the overall sequence, then answer the ten questions without opening the explanations. Beside any uncertain answer, note the paragraph and the missing or contradictory detail. The response fields are for practice only: there is no submit button, automatic marking or saved result. Keep any notes you want to retain. This short lesson does not estimate an IELTS band.
When an earlier sighting needs a second look
A. Bird migration connects places where resources become available at different times. Food, breeding sites and seasonal daylight can all make a journey worthwhile. Migration patterns vary: some birds remain in one area, while others travel long distances. Departure may be influenced by changes in day length, weather and food supply. These broad patterns explain why migration attracts observers, but a local record must still be examined carefully before anyone claims that a particular route or timetable has changed.
B. The following project is fictional. At Willow Marsh, a learning group compared two spring notebooks kept ten years apart. The newer notebook seemed to show that a visiting bird appeared much earlier. Before preparing a public display, coordinator Lina asked the group to copy every entry into a shared spreadsheet. They included the observation date, the location and the length of each visit. Where an old entry lacked a detail, they left the cell empty instead of guessing what the original observer had intended.
C. A difference in observation effort soon emerged. The older group had visited only on Saturday mornings, whereas the newer group had watched the marsh every day. The first recorded sighting therefore did not necessarily mark the first arrival. A bird could have been present between the older visits without being seen. Lina asked the learners to compare Saturday records separately. This would make one part of the comparison fairer, although it could not repair every weakness in the historical notebook.
D. The team also checked descriptions rather than relying on species names alone. Two early entries in the newer notebook described an uncertain identification and included photographs. After reviewing those photographs, the group moved the entries into an unresolved category. They did not erase them. Keeping a visible record of uncertainty would allow a later reviewer to reconsider the decision. The earliest confirmed sighting was consequently later than the date that had first attracted attention, but the group did not treat this correction as a disappointing result.
E. For the display, the learners presented a calendar of confirmed observations alongside a short account of the methods. They declined to announce that the birds had changed their migration timetable, because the notebooks alone could not establish that conclusion. Next spring, the group planned equal-length visits on fixed days and a common identification guide. Lina described the display as a useful baseline for future comparisons. Its value lay in making the evidence understandable, including its gaps, rather than in producing a dramatic headline about the marsh.

Ten questions: record an answer and locate its support
Questions 1–3: TRUE, FALSE or NOT GIVEN
Choose TRUE when the statement agrees with the passage, FALSE when the passage contradicts it, and NOT GIVEN when the passage does not provide enough information to decide. A statement that sounds likely is not automatically TRUE.
Questions 4–6: sentence completion
Write NO MORE THAN TWO WORDS from the passage for each answer. Copy the wording accurately and check that the completed sentence is grammatical. Do not add an explanation in the answer field.
Questions 7–8: matching information
Choose the paragraph, A–E, that contains the specified information. A paragraph may be used more than once. Match the whole idea, not just a repeated topic word.
Questions 9–10: multiple choice
Choose one answer, A, B, C or D. Check the scope of each option: an explanation for one action is not necessarily a claim about every situation.
- To replace all future observation visits
- To review whether early identifications were reliable
- To calculate the distance travelled by each bird
- To prove a change in the migration route
- To announce a proven shift in migration timing
- To show that historical notebooks have no value
- To present usable records with their limitations
- To rank the observers by their experience
Questions 4–6: maximum two words from the passage. Answers are checked manually using the reveals below.
Answers with paragraph evidence
Open one explanation at a time. Before changing an answer, identify whether the mistake concerned vocabulary, a missing fact, the wrong participant or an exaggerated conclusion. A correct guess still needs an evidence check.
1. Reveal answer and explanation
TRUE. Paragraph B says the spreadsheet included the length of each visit. “Duration” paraphrases “length” here. This is a direct match about the information copied, rather than an inference about how long any particular visit lasted.
2. Reveal answer and explanation
FALSE. Paragraph C says the older group visited only on Saturday mornings. Daily watching describes the newer group. The statement transfers a detail from one group to the other, so the passage contradicts it rather than leaving the frequency unknown.
3. Reveal answer and explanation
NOT GIVEN. The passage mentions learners, uncertain identifications and a coordinator, but it does not state the training history of every participant. Calling people learners does not prove that none had professional training. The complete claim about all members cannot be checked.
4. Reveal answer and explanation
spreadsheet. Paragraph B names a shared spreadsheet. Copy this single noun exactly; “notebook” is the original source of entries, not the destination into which the group transferred them. The adjective “shared” is already provided in the question.
5. Reveal answer and explanation
Saturday. Paragraph C says Lina requested a separate comparison of Saturday records. The answer identifies the common observation day, not the newer group’s daily schedule. One word completes the sentence and keeps the distinction between the two recording methods.
6. Reveal answer and explanation
baseline. Paragraph E describes the display as a useful baseline. In context this is a starting reference for future comparisons. “Calendar” describes something included in the display, but it is not the role expressed in the sentence to be completed.
7. Reveal answer and explanation
C. Paragraph C describes the gaps between Saturday visits and explains that a bird might have been present without being observed. Match the explanation, not merely a repeated word: paragraph B introduces the notebooks but does not yet explain this limitation.
8. Reveal answer and explanation
D. Paragraph D moves doubtful entries to an unresolved category and explicitly keeps them available for reconsideration. The question is about preserving uncertainty, not correcting missing cells in paragraph B. Both involve records, but the reasons for the actions differ.
9. Reveal answer and explanation
B. Paragraph D links the photographs to checking uncertain identifications. The outcome is a change in which sighting is confirmed. The passage does not say photographs replaced visits, measured journey lengths or proved a route had changed; those alternatives add unsupported purposes.
10. Reveal answer and explanation
C. Paragraph E emphasises understandable evidence, its gaps and a baseline for comparison. The group expressly avoids announcing a changed timetable. The most suitable answer recognises that a careful, limited account is valuable even without a dramatic conclusion.
Review the reasoning behind your choices
Compare your answers to Questions 1 and 3. The passage explicitly lists information in a spreadsheet but leaves participant qualifications unstated. An answer should depend on that difference in evidence, not on whether a claim sounds plausible. For Question 2, draw two columns labelled older and newer, then place the visit schedules in the correct columns. This simple check prevents a factual detail from being attached to the wrong group.
In this passage, “unresolved” means that a decision has not yet been settled. “Confirmed” signals stronger support for an identification. “Baseline” is the reference used for a later comparison. Notice how these words describe the status or use of evidence rather than a bird’s physical behaviour.
Choose one answer you initially doubted and complete this evidence note: “I selected this answer because paragraph ___ says ___; the alternative would require ___.” If you cannot complete the final part, reread the competing answer rather than simply memorising the key. Your next practice goal should name a process you can repeat, such as checking the speaker or preserving a qualification.
Paraphrase without changing the certainty
Sentence from the passage: The first recorded sighting therefore did not necessarily mark the first arrival.
Rewrite the sentence using “earliest observation” and “might”. Preserve the uncertainty and the difference between an observation and the event itself. Then explain why replacing “might” with “definitely” would change the claim.
Reveal one possible rewrite and the meaning check
Possible rewrite: The earliest observation might have occurred after the birds had already arrived.
This version keeps open the possibility of an earlier arrival without asserting that it certainly happened. “The birds definitely arrived earlier” goes beyond the notebook evidence. A good paraphrase preserves the level of certainty as well as the general subject.
This is an open-ended language exercise, so other accurate rewrites are possible. Check the actor, action, time and level of certainty before judging style. Replacing words with synonyms is useful only when the new sentence still makes the same claim.
Choose the next Reading skill to practise
Continue with short-answer and exact-word practice if your completion answers exceeded the limit. Use matching features to work on attaching details to the correct people or groups. For a change of text type, try two original Academic-style texts. Keep the answer explanations closed until you have made an evidence-based attempt.
