Faithful mediation to a host

A fictional German source says that a Friday school visit will begin at ten instead of nine and asks visitors to bring identification. The learner must send an appropriate Portuguese message to an adult host who will accompany the group and ask whether the revised time is possible. A draft switches between address forms, preserves the old start time and invents a free lunch. It also omits identification because the writer considers that condition a minor detail. The task gives no universal word count or examination penalty; it asks for faithful information, a coherent register and a clear request. The source establishes conditions for this particular invented visit only, not a general legal identification rule or a promise of extra services. The recipient should be able to act without reading the German source.
