In short
More words help only when they develop the requested response. Check the audience, purpose and required content. A long passage on another topic cannot replace a missing decision, reason or next step. Equally, a clear short fragment can still leave parts of the task unanswered.

Consigne originale
Votre collègue vous propose deux salles pour une réunion : l’une est proche mais petite, l’autre plus éloignée mais assez grande. Écrivez-lui pour choisir une salle, expliquer deux raisons et proposer une solution pour le trajet. Pour cet entraînement B1, écrivez au moins 160 mots.
Je choisirais la grande salle : elle peut accueillir tout le groupe et permet de travailler autour de plusieurs tables. Pour le trajet, nous pourrions organiser un départ commun depuis le bureau.
I would choose the large room: it can accommodate the whole group and allows work around several tables. For travel, we could arrange a shared departure from the office.
This extract addresses the choice, two practical reasons and a travel proposal. It would still need appropriate development to complete the full writing task. Useful expansion could explain the group size, compare the nearer room and specify how the shared departure would work.
Quand j’étais enfant, notre école avait un grand jardin. J’y passais beaucoup de temps avec mes cousins. Nous parlions de nos vacances et de nos animaux préférés.
When I was a child, our school had a large garden. I spent a lot of time there with my cousins. We talked about holidays and our favourite animals.
This second extract is grammatical narrative, but it does not help the colleague choose a room or organise travel. Continuing the childhood story would increase the word count while leaving the practical requests unanswered.
Vrai ou faux ? Decide before you see the verdict.
Nommer la solution choisie aide à répondre à cette consigne.
VraiThe prompt asks for a decision, so the choice must be explicit.
Une longue description de mon enfance remplace la décision demandée.
FauxLength does not supply the missing decision or address the colleague’s need.
Expliquer un avantage pratique peut développer un argument pertinent.
VraiA concrete advantage links the choice to the situation.
Ajouter une attaque personnelle contre le destinataire rend le texte plus adapté.
FauxA hostile personal attack conflicts with a cooperative message to a colleague.
Une réponse courte qui oublie deux demandes est complète parce qu’elle est claire.
FauxClarity does not replace required content.
Une concession peut être utile si elle conduit à une solution.
VraiIt can recognise a constraint and explain the compromise.
Le nombre de mots suffit à montrer que le destinataire et le but sont respectés.
FauxAudience and purpose depend on the content and register, not the count alone.
Expand the part that does work
To develop the first extract, explain how the room’s capacity affects participation or how tables support the planned activity. Then acknowledge the longer journey and make the travel proposal specific. This adds content the recipient can use. Avoid adding an unrelated advanced structure just because it seems more impressive.
Use the prompt as a map while drafting: choice, reasons, travel solution, audience. Develop each part with details that connect to the situation. Length then follows purposeful explanation rather than becoming the sole measure of completion.
