D

Mr. Frank shot well and once he had come in fourth in a competition.

Then he went to a big city on business. There he joined the local rifle club. The club had a very good team, which used to take part in a lot of important shooting competitions. One of these took place while Frank was with them. But one of the members of the club's team suddenly fell ill just before the match. The captain had heard of Mr. Frank. He therefore invited Mr. Frank to take the sick man's place.
