C. Modern baseball began about 150 years ago in New York, USA and has been popular sport ever since. It has changed a little bit over the years but the basic game remains the same. Baseball is played with a bat, which is a stick of about 100 cm long, made of metal or wood, and a small hard ball. Each player wears one heavy leather glove to catch the ball. Baseball is played on a special outdoor field.

D. The game of baseball is divided into nine parts, called innings. During an inning, each of the two teams takes its turn to bat, which means trying to hit the ball that is thrown to them by the pitcher of other team. After the ball is hit, the player tries to run and touch three different bases before running to the home base. The team that is not batting tries to catch the balls that are hit, and stop the runners before they score. The team that scores the most runs by the end of the ninth inning wins.
