Answer: "I have spent eleven years as a train driver". The writer's first-hand experience gives authority to observations about passengers, so the reader trusts the claim about carriages going quiet.

Answer: "Last year, our network carried more than forty million trips." The writer uses an official statistic, then points out that what really matters (conversations, connection) is not measured, which turns the authorities' own logic against them.

Answer: The writer concedes that phones are useful ("I use mine"), asks only for one carriage, calls it "a modest experiment" that "costs almost nothing", and accepts that it may fail. This measured tone reduces opposition and strengthens ethos.

Answer: The lonely elderly passenger makes the issue human and moving, and the detail of the dead phone adds gentle irony. Ending with the anecdote leaves the reader with an emotional image that lingers after the reasoning.

Answer: gently ironic

The writer mocks, lightly, the idea that talking to strangers has become shocking.

Answer: Pathos becomes manipulative when the emotion replaces or distorts the evidence, for example an exaggerated or invented sad story, or fear about a danger that is very unlikely. Example: claiming that without the new law, children will die every day, when there is no evidence for this.

Answer: Logos alone can feel cold, pathos alone can feel manipulative, and ethos alone can sound like boasting. Together they make the reader trust the writer, understand the reasoning and care about the outcome.

Model answer: Public libraries deserve more funding, not less. I have volunteered at my local branch every Saturday for three years, and I have watched it become far more than a room full of books. (ethos) It is where a retired engineer teaches coding to teenagers, where job seekers print their job applications and where new arrivals take free language classes. Library visits in our region rose by a fifth last year, while funding fell, which means each dollar is now doing more work than ever. (logos) Cutting that funding would not save money so much as move the cost elsewhere, into unemployment and isolation. (logos) Last winter, a man who had lost his home came in every afternoon simply to sit somewhere warm and read the paper. One day he told me the library was the only place where nobody asked him to leave. (pathos) A city that cannot keep that door open has lost something it will struggle to buy back.
