answers = [
('01','Model answer: “The transition should begin with reliable buses and safe cycle lanes. The main benefit is cleaner air and lower travel costs. Some residents may feel overwhelmed because they need their cars for work, so the city should offer a gradual timetable and affordable travel passes.”'),
('02','Model answer: “The closure could trigger unemployment. Families would spend less, which could devastate local cafés and shops; some might become bankrupt. First, the council should support jobs and temporary income, because this stops the damage spreading.”'),
('03','Model answer: “The app could revolutionize voting by letting people vote securely from home. However, it may backfire if older people or rural citizens lack internet access. Paper voting and digital support centres should remain available.”'),
('04','Model answer: “I would ask who was surveyed, how many people answered, and how the questions were worded. A poll can undermine confidence when it looks scientific but excludes important groups.”'),
('05','Model answer: “At this public assembly, one side wants health and youth activities, while the other fears higher taxes. We need a consensus: a smaller centre, shared funding, and a public report on who benefits.”'),
('06','Model answer: “Parliament should make the immediate flood decision because the danger is urgent. A referendum is valuable for long-term funding choices, but it takes time while the damage may devastate more communities.”'),
('07','Model answer: “The coalition could agree on housing, transparent budgets, and a review after one year. A promise to cancel every tax may backfire because public services still need funding.”'),
('08','Model answer: “I support suffrage at 16 because young people are affected by education, work, and climate decisions. Critics say they lack experience, but people learn responsibility by using it. A vote should be supported by good civic education.”'),
('09','Model answer: “Transport routes should be decided locally because regions know their needs. National security should remain federal law because it requires one standard. Devolution of power can benefit citizens when responsibilities are clear.”'),
('10','Model answer: “First, publish the facts about the scandal. Second, create an independent investigation. Third, hold open meetings with candidates. This can improve voter turnout because people see that wrongdoing is not being hidden.”'),
('11','Model answer: “The company has an interest in profit and jobs; environmental groups have an interest in clean water and safety. Officials should require an independent impact study so that the policy does not compound mistrust.”'),
('12','Model answer: “I would fund hospitals first because urgent care benefits everyone. Students may feel disappointed, and some families may feel overwhelmed by tuition costs, so grants should protect those with low incomes.”'),
('13','Model answer: “The first vote should be respected, but a citizens’ panel could examine the narrow result and propose detailed options. A later vote on those options may create consensus without pretending the first vote did not matter.”'),
('14','Model answer: “The campaign could offer transport to polling stations and simple explanations of candidates. But insulting non-voters might trigger anger and backfire. Respectful messages are more likely to increase voter turnout.”'),
('15','Model answer: “Instead of rebuilding the same vulnerable streets, the city could revolutionize the district with flood-resistant homes, parks that absorb water, and local energy. The transition is costly, so residents must help plan it.”'),
('16','Model answer: “To the local leader: Which decisions can your region manage better than the capital? To the federal law-maker: How will you protect equal services across all regions? This debate tests whether devolution of power is fair.”'),
('17','Model answer: “With proportional representation, a party winning 30% of votes receives roughly 30% of seats. It may improve representation, but parties may need a coalition, which can make decisions slower even when consensus improves.”'),
('18','Model answer: “Citizens may feel overwhelmed because three major systems change at once. Healthcare should change first if services are at risk, followed by schools and taxes. A staged transition gives people time to understand each step.”'),
('19','Model answer: “An unverified scandal can undermine parliament because people may assume all representatives are dishonest. Journalists should verify evidence, citizens should check sources, and politicians should respond with facts rather than attacks.”'),
('20','Model answer: “Our public assembly will discuss safe routes to school. Parents, students, bus drivers, and disability groups will attend. We will send a petition to parliament for safer crossings. A neutral chair and published funding records will limit vested interests.”')]
