Trois annonces à Lyon Part-Dieu : laquelle croire ?
You are accompanying a group of 24 students on a school exchange in Lyon. The group is booked on TGV 6172 to Annecy, and the teacher's printed itinerary says « départ 14 h 42, voie 11 ». At 14 h 20, near the ticket machines, you hear three announcements in quick succession. The first states: « Le TGV 6172 à destination d'Annecy partira voie 11 avec un retard de dix minutes. » A second, twenty seconds later, says: « Les voyageurs du TGV 6172 pour Annecy sont invités à se rendre voie 7 ; le départ est avancé à 14 h 37. » A third adds: « En raison d'un incident technique, la voie 11 est fermée. » Your handwritten notes still read « 11 – 14:42 ». A classmate insists she heard « voie 7, 14 h 47 ». The teacher is at the far end of the concourse buying water, and it is now 14 h 24. The group is spread out and two students have gone to the toilets.

The reliable information is voie 7, départ 14 h 37. The reasoning is layered. First, a later announcement supersedes an earlier one in a station, especially when it gives a cause: the third message explains that voie 11 is closed for a technical incident, which confirms the change of platform rather than contradicting it. Second, the word avancé is decisive: it means the train leaves earlier, not later. Candidates who hear only « retard de dix minutes » and relax will miss the train. Third, 14 h 47 is almost certainly a mishearing of « quatorze heures trente-sept »; the classmate has inverted the numbers. The original itinerary is now obsolete. With 13 minutes left and a scattered group, the correct judgement is to act immediately on the latest complete instruction: platform 7, 14 h 37, and treat the printed sheet as historical information only.

Model: « Monsieur, le TGV part finalement voie 7 à 14 h 37, donc cinq minutes plus tôt que prévu. Il faut rassembler le groupe tout de suite et rejoindre le quai ; je vais chercher les deux élèves qui sont aux toilettes. » The register point matters: the teacher is an adult and the group leader, so vous is required, not « tu ». The message should put the essential facts first (platform, time, change), then the action. « Il faut + infinitive » expresses necessity without sounding like an order to a superior, and « je vais chercher » offers a concrete division of labour. Avoid « on doit se dépêcher » alone: it communicates panic but not the information the teacher needs. Also avoid repeating « retard », which is no longer true.
3. Pourquoi la distinction entre « retard » et « avancé » est-elle décisive ici ?
Read the worked answer
Because the two words point in opposite directions in time. Un retard means the train will leave later than scheduled; avancé means the departure has been brought forward. A candidate who catches only the first announcement will mentally add ten minutes and may sit down or let students go to the shop. A candidate who catches « avancé » knows the margin has shrunk from 22 minutes to 13. The trap is realistic: station announcements often contain both a delay and a platform change, and the delay may belong to an announcement that is later cancelled. The exam-tested skill is not translating each word in isolation but tracking which message is still valid. Here, the sequence « retard » then « avancé » then « voie fermée » means the only operative facts are the new platform and the earlier time.
