What can be inferred from the passage about the kite festival’s new thread rule?
Read the passage: At the annual kite festival in the old city, the sky fills with colour from dawn until dusk. This year, however, the organisers introduced a new rule: only cotton thread could be used, and glass-coated or metal strings were strictly forbidden. Volunteers checked every spool at the entrance and exchanged banned strings for free cotton ones. Some veteran flyers grumbled that their kites would now be cut less often in friendly contests, which made the matches longer. Meanwhile, the local hospital reported that it had treated no festival injuries for the first time in many years.
Correct answer A. Coated strings had previously been a cause of injuries
After coated and metal strings were banned, the hospital treated no festival injuries for the first time in years, implying that such strings had caused injuries before.
