Part1｜独自会話10問
Q1
What will the museum do?
- A. Erase the interview.
- B. Share it under the research agreement.
- C. Seek permission for online distribution.
- D. Assume every recording is public.
英文台本：Woman: The museum plans to release an interview online. Man: Does the original consent allow public access? Woman: It covers only research storage. We must obtain another release first.
Q2
Why is the conclusion uncertain?
- A. Traffic conditions differed.
- B. No crossing was built.
- C. Accidents were never recorded.
- D. Every road was closed.
英文台本：Man: The new crossing seems safer because the accident count fell. Woman: Was traffic volume the same? Man: A nearby bridge was closed during the later survey. Woman: We should adjust for that difference before attributing the decline to the crossing.
Q3
What will the library compare?
- A. Printer colors.
- B. Lifetime costs and support.
- C. Only delivery fees.
- D. The size of the packaging.

- B. No survey was performed.
- C. All cameras were identical.
- D. Detection effort increased.
英文台本：Man: A new reef survey counted more fish. Woman: Did researchers use the same cameras and observation hours? Man: The new survey used better cameras for longer. Woman: Then additional detections cannot prove population recovery alone.
Q5
What is required?
- A. More downloads.
- B. A different poster.
- C. A supervised competence check.
- D. The cancellation of the club.
英文台本：Woman: The science club wants to operate the analyzer tomorrow. Man: Several students downloaded the instructions but have not passed the practical safety assessment. Woman: We should complete the required checks before use.

Part2｜独自説明文5篇・10問
Airport bird safety and habitat
英文台本：A fictional airport is reviewing how birds use the land near its runways. Some managers suggested removing all vegetation, but ecologists warned that such changes could attract other species and erode soil. The airport is comparing recorded strikes, near misses, seasonal movement and aircraft activity. It is also improving waste handling to reduce food sources that attract birds. Officials will trial targeted measures before using them everywhere. They emphasize that a high bird count alone cannot describe the complete risk, since location and flight operations matter.
Q11
Why is removing all vegetation questionable?
- A. Every airport has no birds.
- B. It may cause other ecological or safety problems.
- C. All vegetation is legally protected.
- D. It eliminates all flight activity.
Q12
What will airport staff examine?
- A. Only tree counts.
- B. Only ticket sales.
- C. Only advertising.
- D. Strikes, species behavior and operating conditions.
Citizen telescopes and observation quality
英文台本：Several community observatories have started measuring the brightness of stars. Their results initially differed widely, and volunteers assumed some devices were defective. Scientists explained that clouds, atmospheric turbulence, light pollution and exposure settings may account for differences. They proposed using reference stars and recording the conditions under which each photograph was taken. The team will compare selected results with independent measurements. Its purpose is to develop meaningful observations, not simply generate a large number of images.
Q13
Why may the observations differ?
- A. Every telescope was broken.
- B. No stars were visible.
- C. Viewing conditions and settings varied.
- D. The cameras were never installed.
Q14
What would make the data more comparable?
- A. Reference calibration and consistent records.
- B. More publicity posters.
- C. Ignoring cloud cover.
- D. Removing all old data.
Public footpaths during construction
英文台本：A fictional town is rebuilding uneven public footpaths. The completed design includes safer crossings and accessible surfaces, but the construction detour creates difficulties. One temporary route includes stairs, while another adds a long walk to the nearest bus stop. Engineers intend to test actual journeys with residents who use mobility aids rather than rely only on a planning map. Managers will also record how quickly barriers are removed and whether local shops remain reachable. They will evaluate practical access, safety and costs, not merely the number of meters resurfaced.
Q15
What is a problem with the temporary detour?
- A. The town has no roads.
- B. Every route is identical.
- C. No works are scheduled.
- D. Stairs may exclude some users.
Q16
What is the intended success measure?
- A. Only construction length.
- B. Safe, usable routes and manageable impacts.
- C. Only the appearance of new paving.
- D. Only the number of workers.
Metals recovered from electronics
英文台本：A fictional cooperative is assessing how to recover useful metals from discarded electronics. Supporters hope to reduce demand for some newly mined resources. Technicians warn that different devices contain different metal concentrations, and dismantling may expose workers to hazards. Chemical extraction consumes energy and can leave residues requiring safe disposal. The cooperative will measure actual usable output, electricity consumption, worker safety and cost. It will compare alternative processes before building a permanent facility. The number of collected devices does not establish environmental benefit.
Q17
Why are collection totals misleading?
- A. All electronics contain the same metal amounts.
- B. Every device is immediately reusable.
- C. Actual recovery and processing impacts vary.
- D. Recycling never needs energy.
Q18
What will the cooperative consider?
- A. Only collection bins.
- B. Only publicity.
- C. Only the size of the warehouse.
- D. Usable output, safety, energy and residues.
Preservation of old video interviews
英文台本：A community archive is converting old video interviews into files usable on modern computers. Staff found that some converted versions had audio synchronization errors and unclear dates. They decided to retain originals and display correction histories. Some participants had approved research storage but not unrestricted online release, so access decisions must also be reviewed. Managers will measure whether recordings remain playable, correctly documented and legally accessible over time. Converting more files is not by itself evidence of successful preservation.
Q19
Why keep original recordings?
- A. Conversion can introduce errors.
- B. Every converted file is perfect.
- C. No permission rules exist.
- D. The original voices must be deleted.
Q20
How will success be evaluated?
- A. Only total file size.
- B. Accuracy, permission and long-term usability.
- C. Only upload speed.
- D. A guarantee that every file is public.

Part4｜インタビュー2問
英文台本：Interviewer: Your council is planning a shared battery-storage program for public buildings. Why share equipment? Director: Some facilities need emergency power only occasionally, and a shared arrangement might reduce duplicated capacity. However, there are maintenance and safety requirements. Interviewer: Are initial results promising? Director: We installed several batteries, but that says little about how much useful electricity they deliver during outages. We will measure service continuity, failures and replacement costs. Interviewer: Could the program reduce bills? Director: Possibly, depending on when electricity is bought and how much is used. We cannot promise savings based on one short trial. Interviewer: Do all sites have identical needs? Director: No. A clinic may need far more reliable backup power than a meeting hall. Trained staff must monitor exceptional conditions even when routine scheduling is automated. Interviewer: What would justify wider adoption? Director: Dependable backup power, fair arrangements and benefits that exceed all operating and equipment costs.
Q26
Why is the number of installed batteries insufficient?
- A. Every battery eliminates maintenance.
- B. All facilities have the same needs.
- C. Actual delivered power and service reliability must still be evaluated.
- D. The council has stopped the project.
Q27
What would justify expansion?
- A. Only website traffic.
- B. Only publicity.
- C. A guarantee of stable electricity prices.
- D. Reliable backup supply with benefits exceeding full costs.
