森林での計画的な火入れと地域の煙害
A fictional woodland authority is considering controlled fires in areas where dry vegetation has accumulated. Specialists believe carefully planned low-intensity burning could help manage particular fire-adapted habitats and reduce some fuel loads. The authority has emphasized that this is a limited option, not a universal way to prevent wildfires.
Conditions can change rapidly, however. Stronger wind or unexpected dry weather may allow a planned fire to cross its intended boundary. Smoke can also reach nearby settlements and affect residents with respiratory difficulties. Managers therefore need to [23] _____ before approving any operation.
Officials are comparing controlled burns with mechanical clearing and habitat restoration. Some techniques cost more in labor, while burning can proceed only during suitable weather. The plan should [24] _____, with clear communication to residents rather than one fixed timetable for every site.
A pilot will measure vegetation, smoke, near-miss incidents, habitat condition and operating costs. The aim is [25] _____ rather than burning the largest possible area.
Q23
- A. evaluate weather, containment and smoke exposure
- B. assume wind can never change
- C. allow untrained volunteers to act without supervision
- D. exclude nearby residents from all notices
Q24
- A. require every site to use the same approach
- B. adapt methods and warnings to local circumstances
- C. remove all ecological measurements
- D. treat public communication as unnecessary
Q25
- A. eliminating every future natural fire
- B. maximizing the number of burn announcements
- C. reducing relevant risks while protecting people and habitats
- D. ensuring smoke has no possible effects
学校の水道と鉛を含む旧配管部品
A fictional school district is reviewing older water fixtures because some components may contribute to lead contamination. Officials have considered replacing affected taps and connectors, particularly in buildings with outdated plumbing. Parents welcome inspections but want assurance that safe drinking water is available during repairs.
Engineers caution that installing a new tap does not prove that an entire water system is safe. Remaining pipes, the chemistry of water and the length of time water sits unused can influence test results. Therefore, the district should [26] _____ rather than judge progress only by the number of fixtures installed.
Schools are discussing temporary drinking-water alternatives and clear updates for families. Staff also need to know when sampling must be repeated after repairs and how results will be recorded. Officials aim to [27] _____, recognizing that one favorable measurement does not guarantee conditions will never change.
A pilot will compare confirmed water quality, service interruptions, correction times and maintenance expenditure. Its goal is [28] _____, not an impressive tally of replacement work.
Q26
- A. assume all water systems are identical
- B. test complete water pathways under appropriate sampling conditions
- C. remove independent checks from the process
- D. accept every supplier claim without evidence
Q27
- A. avoid informing families until all work is finished
- B. treat every initial reading as permanently final
- C. provide usable alternatives and explain monitoring results clearly
- D. require children to perform technical inspections
Q28

デジタル遺産と故人のオンライン記録へのアクセス
A fictional consumer-support organization is examining how families can handle digital accounts after the account holder dies. Photographs, messages and purchased media may be stored on online platforms rather than on devices held by relatives. Some services permit users to nominate a contact, but the powers granted to that person differ.
Legal advisers emphasize that paying for online content does not automatically create a transferable right to distribute it. A private conversation may contain information about another person who has not consented to publication. Even when a deceased user wanted certain files preserved, relatives may need to follow platform terms, applicable law and secure identity checks.
The organization proposes clearer instructions explaining the difference between downloading personal photographs, closing an account and obtaining access to private messages. Consumers are encouraged to review service-specific options and record lawful preferences in advance. However, a password list from several years ago may be outdated, and informal sharing of credentials can increase security risks.
Some families want rapid access to treasured recordings, while others worry about intrusive disclosure of sensitive messages. The organization is considering procedures that allow limited review and appeals rather than unrestricted access for every relative. It also wants providers to explain what happens to data if a service is discontinued.
The evaluation will focus on accurate handling of authorized requests, user understanding and protection of third parties. The goal is dignified, lawful treatment of digital records, not the automatic transfer of every online account.
Q29
Why might relatives lack the right to obtain all digital account contents?
- A. Licenses and third-party privacy may restrict access and redistribution.
- B. Every piece of online content is freely transferable.
- C. All platforms use identical inheritance policies.
- D. Online accounts cannot contain private messages.
Q30
What is recommended for people planning ahead?
- A. Publishing a public list of passwords.
- B. Reviewing service-specific options and recording lawful preferences.
- C. Assuming one handwritten note overrides all rules.
- D. Sharing all messages with relatives immediately.
Q31
What is the main goal of clearer digital legacy rules?
- A. To make every paid license permanent.
- B. To eliminate privacy after death.
- C. To enable secure authorized handling with respect for others.
- D. To let any claimant sell private correspondence.
マングローブ植林と海岸侵食への適応
A fictional conservation group has proposed planting mangroves along an eroding coast. Supporters hope that suitable trees may provide habitat and reduce the force of certain waves. Local volunteers have offered to grow seedlings, and initial reports have emphasized how many trees could be planted.
Ecologists warn that survival depends on water depth, tidal variation, salinity and the species selected. A mangrove planted in the wrong location may die or damage an existing habitat. Even a high first-year survival rate would not prove that severe storms could no longer cause erosion.
Small-scale fishers also use shallow waters near the proposed sites. Some worry that planting could obstruct boat access, while others see potential benefits from healthier habitats. Scientists recommend mapping local conditions and consulting coastal users instead of placing seedlings uniformly along the entire shoreline.
The conservation group plans a series of small trials, comparing natural regeneration with active planting and other protective methods. Monitoring will include species survival, habitat changes, shoreline measurements, costs and the continued ability to use coastal routes.
The objective is durable ecological and protective value where planting is appropriate, not the maximum number of seedlings distributed at public events.
Q32
Why may a large planting campaign fail?
- A. Sites and species may not match the physical conditions.
- B. Every mangrove grows equally well in all water depths.
- C. High seedling counts guarantee storm protection.
- D. No mangrove needs suitable soil.
Q33
Which stakeholder concern is described?
- A. Only the cost of souvenir shops.
- B. Access to shallow water used by small fishing boats.
- C. Internet bandwidth at the planting site.
- D. Ownership of nearby satellites.
Q34
What will the group compare before wider adoption?
- A. Only publicity photographs.
- B. Only the total number of volunteers.
- C. Natural regeneration, targeted planting and measured outcomes.
- D. A universal planting plan without field checks.
Q35
Which result best demonstrates success?
- A. The largest possible event attendance.
- B. A guarantee against all future storms.
- C. No future maintenance expenditure.
- D. Verified habitat and coastal benefits without unjustified local disruption.
