Part1｜独自会話10問
Q1
Why is the conclusion uncertain?
- A. Traffic volume changed during the comparison.
- B. The crossing was removed.
- C. No accidents were recorded.
- D. All residents stopped traveling.
英文台本：Woman: The town reported fewer accidents after adding a crosswalk. Man: Was traffic the same in both periods? Woman: A nearby bridge was closed during the later survey. Man: Then traffic changes might explain the decline. We should compare similar conditions.
Q2
What will the museum do?
- A. Delete the photograph.
- B. Treat the date as provisional.
- C. Guarantee the year is correct.
- D. Publish all notes as verified.
英文台本：Man: The museum’s catalogue gives 1905 as the date of a photograph. Woman: Does that date appear on an original record? Man: Only on an unsigned note written later. Woman: Let’s label it as an estimate until the building history is checked.
Q3
What will be measured separately?
- A. The number of advertisements.
- B. The price of the laboratory building.
- C. Practical assessments that students have completed.
- D. All students as fully qualified.
英文台本：Woman: Students downloaded the laboratory training manual. Man: Does that prove they can operate the device safely? Woman: No, they still need supervised testing. Man: Then let’s report completed assessments separately from downloads.
Q4

- A. A larger lecture hall.
- B. A change of speaker.
- C. Only a notice about the broadcast.
- D. Permission for public recording distribution.
英文台本：Man: Can we stream the public historian’s lecture? Woman: Her agreement permits only an in-person audience. Man: What about posting an audio recording? Woman: We need an additional release from the rights holder first.

英文台本：Man: The utility says new filters removed all pollutants. Woman: Were all wells tested? Man: Only three showed lower concentrations. Woman: Then report those measurements without claiming that every well is safe.
Part2｜独自説明文5篇・10問
Rain gardens and flood measurement
英文台本：A fictional town installed rain gardens on streets that sometimes flood. Residents welcomed the new plants, but engineers cautioned that planted area is not equivalent to actual stormwater retention. Soil composition, rainfall intensity and clogged drains influence performance. A garden may help during moderate rain but offer limited protection during extreme storms. The municipality will compare water levels and infiltration under similar weather conditions. Maintenance teams will also check that the landscaping does not block accessible pedestrian routes. Officials want evidence of useful drainage and safe public access, not simply a larger total of green space.
Q11
Why is the planted area not enough to show flood protection?
- A. Actual retention depends on soil and weather.
- B. Every garden contains identical soil.
- C. No rain gardens were built.
- D. Flooding always disappears after planting.
Q12
What else will officials assess?
- A. Only the number of flowers.
- B. Infiltration, maintenance and safe pedestrian access.
- C. Only public photographs.
- D. A promise that no storm will occur.
Community recordings and consent
英文台本：A fictional archive gathered oral histories in a heritage language. Volunteers hoped to place the recordings online, but some participants had consented only to research storage. Other recordings contained cultural information that contributors did not want distributed without restrictions. Editors introduced different access categories for preservation, classroom use and public distribution. Language specialists also recorded local pronunciation differences. The archive plans to retain source files and correction histories while consulting contributors. Managers will evaluate accuracy, consent and educational usefulness. Uploading more files is not automatically a measure of responsible preservation.
Q13
Why do some recordings need separate publication permission?
- A. Every recording was made in public.
- B. All archives are free of restrictions.
- C. Consent to preservation may not permit unrestricted online distribution.
- D. Recording files have no cultural significance.
Q14
What will the archive retain?
- A. Only upload totals.
- B. Only one standardized pronunciation.
- C. Only promotional excerpts.
- D. Source recordings, access permissions and correction history.
Sharing expensive laboratory instruments
英文台本：A university introduced online reservations for scientific instruments. The first report showed that nearly every available hour was booked. Staff then found that some researchers made reservations but never arrived, preventing others from using idle equipment. Managers introduced cancellation rules, waiting lists and protected maintenance periods. Certain devices require supervised training before use. The university now plans to measure completed sessions, equipment reliability, fair access and operating costs. A calendar that appears full is not necessarily evidence that the instruments are being used efficiently.
Q15
Why is a full booking calendar potentially misleading?
- A. Reserved time may not be used.
- B. Every instrument is broken.
- C. No researchers need equipment.
- D. Every reservation is always completed.
Q16
What will the university evaluate?
- A. Only website visits.
- B. Completed equipment use, fair access and operating costs.
- C. Only printed schedules.
- D. A guarantee of no maintenance.
Seabird surveys and detection effort
英文台本：A fictional conservation group reported more seabird sightings after habitat restoration. Independent researchers noticed that the latest surveys used additional observers, longer periods and improved cameras. Increased detection could therefore reflect changes in observation effort rather than a larger bird population. The group is planning standardized surveys and may compare nesting outcomes when suitable. Seasonal weather and fishing activity will also be examined. Some nesting sites will remain confidential to prevent disturbance. Managers want reliable ecological evidence, not the greatest number of photographs collected.
Q17
Why do more bird photographs not prove population recovery?
- A. Birds never move.
- B. All cameras are identical.
- C. Detection effort and equipment changed.
- D. The site had no restoration.
Q18
What could strengthen the conclusion?
- A. Only more posters.
- B. Only more visitors.
- C. A guarantee that nesting increases.
- D. Comparable surveys and appropriate breeding observations.
Inspections of old railway tunnels
英文台本：A regional railway is examining older tunnels affected by moisture and blocked drainage. Inspectors have seen visible cracks, but engineers warn that photographs may not reveal internal structural defects. The company plans to combine visual inspections with targeted tests and maintenance. Repair work may interrupt train services, so alternative transport and accurate passenger notices are necessary. The evaluation will consider safety, repair outcomes, disruption and long-term costs. The number of inspection photographs is not a complete measure of whether risks have been identified and managed.
Q19
What can ordinary tunnel photographs miss?
- A. Internal structural deterioration.
- B. Every visible crack.
- C. The existence of train services.
- D. All surface water.
Q20
Which outcomes will guide repairs?
- A. Only the number of images.
- B. Actual safety, service continuity and full costs.
- C. Only the company’s logo.
- D. Only a publicity campaign.

Part4｜独自インタビュー2問
英文台本：Interviewer: Your city introduced a mobile library service for residents who have difficulty visiting branches. What problem were you addressing? Director: Some people live far from public transport, while others face mobility barriers. The vehicle visits community centers on scheduled days. Interviewer: The first report mentions many registrations. Does that establish success? Director: Not entirely. Some people register but never borrow, and others still cannot reach the stops. We measure completed loans and unfulfilled requests. Interviewer: Could e-books replace the vehicle? Director: They are useful for some residents, but not everyone has a suitable device or reliable internet. We therefore keep printed materials and telephone booking. Interviewer: What about expense? Director: The vehicle needs staff, fuel and maintenance, and we compare this approach with using existing local facilities. Interviewer: What would justify expansion? Director: Evidence that underserved residents can obtain materials safely and reliably at a manageable cost. Registration figures alone are not sufficient.
Q26
Why does the director question the meaning of registrations?
- A. Every registered person borrowed immediately.
- B. All residents have identical access.
- C. Some registrations do not lead to borrowing while other needs remain unmet.
- D. The library has no digital materials.
Q27
What will determine expansion?
- A. Only online advertising.
- B. Only the number of library vehicles.
