Ответ:
Lady Grey’s cat, Pepper, leaves the house. It goes to the park. It picks the birds in the park. Then, two dogs chase Pepper. Pepper runs away and climbs a tree. The dogs sit under the tree. They wait for Pepper.
Lady Grey arrives. She hits the dogs on the nose with her umbrella. The dogs run away. Lady Grey picks Pepper up. They go home.
В предложении «It picks the birds» по смыслу, вероятно, должно быть it watches the birds; однако в списке глагол watches имеется, поэтому правильное заполнение: watches.
