1. F

The paragliders decided not to practise because the weather was so bad.

(One morning, as they were getting ready to take off, they noticed a thunderstorm approaching. However, they decided to carry on.)

2. T

The weather got worse during the morning.

(Unfortunately, as the competitors took off, the weather quickly got worse.)

3. T

The storm damaged one of the wings of her glider.

(But fortunately, her glider, which was spinning above her head, was still in one piece.)

4. T

Ewa was still able to compete in the World Championships.

(There's no logical reason why she survived. Ewa had frostbite on her ears and legs, but a few days later, she competed in the World Championships.)
