Fill in the blanks, thinking back to the answer to the question following each section numbers. Read the finished summary aloud.

Curling has become popular because of the ①（strategy and skill） it requires. In the game, stones and brooms are used. To score points, each team must not only try to place their stones ②（closest to the center〔as close as possible to the center〕） of the house, but also prevent the other team from doing so. Sometimes a team will use the strategy of “③（blank end）” to get last-stone advantage, which makes it easier to score points. ④（Sweeping （the ice with brooms）） also plays an important role because doing so changes the stone’s path. Curling requires a great amount of ⑤（mental skill） in addition to physical skill, so it is sometimes called “chess on ice”.
