Part1｜会話10問・独自台本
会話1
Q1. What will the organizers tell participants?
- A. The hall is permanently closed.
- B. The venue is provisional pending a safety check.
- C. The lecture has already been canceled.
- D. The inspection report has been approved.
英文台本：Woman: The community hall can host our lecture on Friday, but the ventilation inspection ends at noon. Man: Could we confirm the evening session now? Woman: The facilities officer says approval depends on the inspection report. We can keep the date provisionally, but we shouldn’t announce the venue as certain. Man: Then I’ll tell participants that a final notice will follow.
会話2
Q2. Why does the woman reject the causal claim?
- A. Other changes could also explain the increase.
- B. No scholarship applications were submitted.
- C. The advertising campaign was never launched.
- D. Every applicant received a scholarship.
英文台本：Man: The new scholarship portal received twice as many applications. Doesn’t that prove the advertising campaign worked? Woman: It may have helped, but the application fee was removed and two extra centers opened. Man: So several factors changed together. Woman: Exactly. Let’s report the increase without attributing it entirely to the campaign.
会話3
Q3. What must happen before online publication?
- A. Every recording must be deleted.
- B. The museum must close temporarily.
- C. The archive must change its name.
- D. Separate publication permission must be obtained.
英文台本：Woman: Can we include those recorded interviews in the public exhibition? Man: The families agreed to preserve them for research. Woman: Does that cover online publication? Man: No. A speaker’s voice might still reveal their identity, so a separate release is required. Woman: I’ll obtain it before we put any clips online.
会話4
Q4. Why is the temperature result uncertain?
- A. The sensor has no measurements.
- B. The region has certainly cooled.
- C. The sensor’s new location may affect readings.
- D. The reference station has been destroyed.
英文台本：Man: The overnight temperature sensor shows a sudden jump. Woman: Was it moved during maintenance? Man: Yes, closer to a wall that receives afternoon sunlight. Woman: We should compare its readings with a reference station before presenting the change as a regional trend. Man: I’ll request that comparison today.
会話5
Q5. What will the man do first?
- A. Cancel every registration.
- B. Confirm the instructor’s availability for Saturday.
- C. Reserve the smaller room for thirty people.
- D. Publish a definite new date immediately.
英文台本：Woman: The health seminar has thirty registered participants, but Room C holds only twenty-four. Man: The larger room is free on Saturday, although the instructor has not confirmed that day. Woman: Let’s ask her first. We shouldn’t move the event until she agrees. Man: I’ll contact her before changing the booking.
会話6
Q6. What is the recommended response?
- A. Repeat the survey with comparable sampling routes.
- B. Declare the species extinct.
- C. Discard all previous data immediately.
- D. Assume maintenance cannot affect observations.
英文台本：Man: The coastal survey found fewer fish than last year. Woman: Were the same areas sampled? Man: No, several boats had to avoid the estuary during maintenance. Woman: Then the lower count could reflect a changed route. We should note the limitation and repeat the observation under comparable conditions.
会話7
Q7. What explains the waiting list?
- A. The title was never published.
- B. Every reader lacks a computer.
- C. The library has no internet connection.
- D. The license restricts simultaneous borrowing.
英文台本：Woman: Our digital library has a waiting list for a popular title. Man: But digital books don’t occupy shelf space. Woman: The publisher’s license permits only a limited number of simultaneous loans. Man: Can we obtain more licenses? Woman: Possibly, but we need to compare renewal costs first and explain the restriction to borrowers.
会話8
Q8. What will the company do?
- A. Replace all vehicles immediately.
- B. Stop handling heavy equipment permanently.
- C. Test bikes on appropriate loads while keeping vans for heavier ones.
- D. Ignore the certified weight limit.
英文台本：Man: The electric delivery bikes work well for light parcels. Woman: Can we use them for every shipment? Man: No. Some equipment exceeds their certified weight limit. We should retain vans for those loads and trial bikes on suitable routes. Woman: Agreed. Let’s track costs and delivery reliability before expanding.
会話9
Q9. What will the school consider?
- A. Changes in occupancy and weather.
- B. Only the price of the insulating material.
- C. The number of school clubs.
- D. A guarantee that insulation caused every reduction.
英文台本：Woman: Our school reduced electricity use after installing insulation. Man: That’s encouraging, but several classrooms were closed during renovations. Woman: So lower occupancy may have affected the comparison. Man: Yes. Let’s adjust for room usage and weather before estimating how much insulation saved.
会話10
Q10. How will the museum revise the label?
- A. It will claim the purpose is certain.
- B. It will describe ceremonial use as a possible interpretation.
- C. It will remove all information about the object.
- D. It will stop the exhibition permanently.
英文台本：Man: The museum label says the ancient container was used exclusively for ceremonies. Woman: Is that established? Man: No, there are competing interpretations. Woman: Then we should describe ceremonial use as one possibility, not a proven fact. Man: I’ll revise the wording and retain the verified discovery details.
Part2｜説明文5篇・独自10問
河川の微小プラスチックと試料採取
読み上げ用英文台本：A fictional river research team collected water samples before and after a new waste-reduction campaign. The number of plastic fragments found in several samples fell. Some campaigners took this as evidence that the program had worked. However, the researchers explained that water flow, rainfall and the locations of sampling points had also changed. A few samples were collected near the surface, while others came from deeper water. Because these differences could affect measured concentrations, the team planned to standardize sampling depth and timing. It also wanted to record the volume of water analyzed and have a second laboratory examine selected samples. The scientists supported efforts to reduce pollution, but they cautioned that one promising measurement could not establish a long-term river-wide decline. They hoped that transparent methods would make later comparisons more meaningful.
Q11
Why is the apparent decline in plastic fragments uncertain?
- A. All sampling conditions were identical.
- B. Different water conditions and sampling methods could affect the results.
- C. The campaign was legally prohibited.
- D. Every sample contained no water.
Q12
What will the scientists do next?
- A. Stop measuring plastic completely.
- B. Assume one sample proves long-term recovery.
- C. Change every result to zero.
- D. Standardize collection and seek independent checks.
山林の自動録音と動物保全
読み上げ用英文台本：A conservation group installed automatic audio recorders in a forest to monitor bird calls. The devices produced thousands of files, and software classified many recordings without human assistance. Organizers initially celebrated the rising number of detected calls. Yet ecologists noted that better microphones and a new recognition model could themselves increase detection rates. A louder recording did not necessarily indicate more birds, and some species were harder to identify than others. The team began testing the software against manually reviewed samples and recording device settings for each observation period. It also examined whether breeding habitat and food availability had changed. These checks took time, but they helped distinguish improvements in technology from ecological recovery. The group’s priority was not to maximize the number of audio files but to build evidence that could guide responsible conservation decisions.
Q13
Why may detected bird calls have increased?
- A. New microphones and software may detect more sounds without more birds.
- B. Every bird species disappeared.
- C. The forest had no recorders.
- D. Every recording was manually created.
Q14
What is the purpose of manual review?
- A. To destroy all sound recordings.
- B. To eliminate ecological monitoring.
- C. To check whether automated classifications are reliable.
- D. To guarantee identical habitats.
食品支援団体の配送需要予測
読み上げ用英文台本：A regional food charity introduced software to predict demand at its distribution sites. The system used historical pickup numbers, seasonal weather and local event schedules. Initially, a successful week encouraged managers to consider making every delivery automatic. Volunteers warned that past collection totals did not capture people who could not travel to a distribution site. Severe weather might also prevent recipients from arriving even when their need remained high. The charity therefore invited feedback from people who had missed earlier services and added a process for staff to override automatic decisions. It measured food spoilage, unmet requests and the cost of emergency transfers. Managers concluded that forecasts could support planning, but a high prediction score was not the same as meeting community needs fairly.
Q15
What is missing from past pickup figures?
- A. The names of every employee.
- B. The needs of people unable to reach distribution sites.
- C. All seasonal weather information.
- D. A guarantee of food storage.
Q16
Why retain human overrides?
- A. To forbid all forecasting tools.
- B. To remove volunteers from the program.
- C. To assume no forecasts can ever be helpful.
- D. To respond when software recommendations miss real needs.
科学講座の字幕と不確実性
読み上げ用英文台本：A public science lecture series introduced automated captions to help audience members follow presentations. Visitors welcomed the new service, but specialists noticed that certain technical terms and expressions of uncertainty were transcribed incorrectly. In one case, a speaker who said that a result might occur appeared to state that it would definitely happen. Organizers invited people who relied on captions to test the system and added human review for important passages. Some viewers preferred immediate text, whereas others accepted a short delay in return for accuracy. The team compared error severity, comprehension and staffing costs rather than assume that one setting would suit every event. They planned to expand the program only after finding a reliable approach for different types of lectures.
Q17
What was one serious captioning error?
- A. A possibility was presented as a certainty.
- B. The lecture was never delivered.
- C. All vocabulary was transcribed correctly.
- D. No audience member could read.
Q18
Why test captions with actual users?
- A. To increase publicity alone.
- B. To prohibit human review.
- C. To assess comprehension and the balance of delay and accuracy.
- D. To guarantee one setting suits everyone.
地域修理センターの安全管理
読み上げ用英文台本：A community repair center helped residents fix small appliances rather than discard them. At first, organizers counted the number of items brought to each workshop and described the rising total as environmental progress. Technicians noted that some items could not be repaired safely and that other repaired products were stored rather than used. Electrical work also required training and suitable inspection procedures. The center began recording the number of items still in service months later and the maintenance costs of shared tools. It consulted qualified specialists before accepting more complex repairs. Volunteers worried that complicated requirements might discourage participation, so managers proposed simple guidance for low-risk tasks and stricter supervision for hazardous ones. The program would be evaluated by safe reuse and actual disposal reductions rather than workshop attendance alone.
Q19
Why are workshop attendance numbers incomplete evidence?
- A. Every appliance is equally easy to repair.
- B. They do not establish that items remain safely in use.
- C. All tools are free to maintain.
- D. Repair centers cannot count visitors.
Q20
How will the center manage risk?
- A. Let volunteers attempt every high-risk task.
- B. Eliminate all practical guidance.
- C. Stop repairing low-risk items.
- D. Use proportionate guidance and specialist supervision for hazardous work.

Part4｜長尺インタビュー2問
英文台本：Interviewer: Your library now lends measuring instruments to residents. What prompted the program? Director: Community groups wanted to examine noise and indoor temperatures without purchasing expensive devices. We thought shared tools could help them ask informed questions. Interviewer: Can the resulting measurements be used in official decisions? Director: Sometimes they reveal issues worth investigating, but they do not automatically meet the standards of accredited monitoring. Devices require calibration, and measurements made at different times may not be comparable. We provide guidance and ask borrowers to record how and where readings were taken. Interviewer: Wouldn’t professional equipment be more reliable? Director: For certain purposes, yes. But responsible community observation can complement specialist work. The important thing is to state the limits of what a finding establishes. Interviewer: What about maintenance? Director: We inspect devices, replace batteries and train borrowers. Some instruments are popular while others are rarely used. Before expanding the collection, we will compare those costs with actual learning and community participation. Interviewer: So how do you define success? Director: Residents using equipment responsibly and understanding what their observations can and cannot show. The number of loans alone is insufficient.
Q26
Why does the director distinguish community data from accredited monitoring?
- A. All measuring instruments are inaccurate.
- B. The library refuses any research use.
- C. Community measurements may be informative without meeting official controls.
- D. Professional monitoring has been prohibited.
Q27
What will determine whether the program expands?
- A. Only the number of promotional posters.
- B. Only the number of instruments.
- C. A guarantee that no tool needs maintenance.
- D. Useful learning and responsible use relative to costs.
