La freccia dell'autobus (The arrow on the chart)
QCER B2370 parole
On Thursday, the council published a chart about its evening bus trial. A green arrow rose from 420 journeys in the first month to 588 in the third. Its headline said the service was working. Supporters shared the image; opponents asked why an expensive bus needed a chart to defend it. Both sides treated the arrow as a verdict.
Mara, who helped at the public library, welcomed the increase. She had watched an older visitor leave a book club early because the last bus departed before the discussion ended. Yet the chart omitted two changes: the council added a later departure in month two and extended the route to the hospital in month three. Total journeys could rise even if each hour of service attracted the same number of passengers. The figures were accurate, but the headline claimed more than they supported.
At a public meeting, the transport officer accepted this point. The council counted boardings, not complete journeys. It knew how many people got on, but not whether they were travelling to the hospital, returning from work or visiting friends. It had deliberately avoided collecting names. Mara did not ask it to start. She suggested publishing boardings per hour of service and asking volunteers to record, without identifying anyone, which stops were used on two sample evenings. That would still be a small sample, she said, but readers would know its limits.
An opponent argued that the trial should end because the chart was misleading. Mara disagreed. A weak headline did not make the bus useless; it made the case for continuing the trial more carefully. The book club visitor could now stay until the end. That mattered even if it was invisible in an upward arrow. Mara wanted another three months, with the cost published alongside passenger figures and a rule for success stated in advance. If the figures then disappointed, the decision would be harder but more honest.
The council removed the headline the following week. The arrow stayed, with a note explaining the extra departure and longer route. Some called the change an admission of failure. Mara thought of it as a beginning: the figures had not become less useful when their limits appeared beside them.

Domande
Si risponde con il testo davanti. Non è memoria: è capire.
What is Mara's main objection to the chart?
The headline overstates what the figures establish. — Il numero di corse è corretto; la conclusione che il servizio funzioni già non ne deriva senza considerare i cambiamenti dell'offerta.
The evening bus followed exactly the same route and timetable throughout the three months.
False — Falso: nel secondo mese è stata aggiunta una corsa più tarda e nel terzo il percorso è stato prolungato fino all'ospedale.
Why does Mara propose counting boardings per hour of service?
To compare demand after allowing for extra service — Il totale può aumentare perché l'autobus circola per più ore; misurare per ora di servizio rende il confronto più equo.
What does the transport officer say the council's data cannot establish?
The destinations and purposes of individual trips — Il sistema conta le salite, ma non registra la destinazione completa né il motivo del viaggio.
What is Mara's response to the proposal to end the trial immediately?
Extend it with published costs and a prior success rule — Chiede altri tre mesi e che costi, misura e criterio di successo siano pubblicati prima di decidere.
Why does Mara see the revised chart as a beginning?
It makes the limits available for the next decision — La freccia resta, ma ora se ne spiegano i limiti; così il pubblico può valutare la fase successiva con informazioni migliori.
