💡 Detailed Explanation
The female student points out that paper cups are already stocked, so there is no need to buy them. Regarding the board (看板), the male student says he will make it now ('materials are bought, so I will make it in a hurry now'). She then offers to handle the projector check ('I will do the connection test for the projector, so you concentrate on completing the board'). Therefore, he must prepare the board.
