The rooftop gardening talk
Text: an original contemporary report-style practice extract.
A community centre transferred Saturday’s rooftop gardening talk to an indoor room after forecasts warned of strong winds during the session. The starting time remained unchanged, and everyone with a booking could still attend. The speaker was available as planned, and no fault had been found with the rooftop surface. Organisers confirmed that the change was not caused by low ticket sales.
Identify one reason, from the extract, why the gardening talk was moved indoors.
