Abstract: It is determined whether execution is to be carried out in a first mode or in a second mode, according to a user's selection operation. In the first mode, a movement of a player object is controlled according to the user's movement operation, and a movement of a non-player object is automatically controlled. Positions of the player object and the non-player object are changed according to the user's position changing operation such that a relative positional relationship between the player object and the non-player object for use in the second mode is a first positional relationship. In the second mode, movements of the player object and the non-player object are automatically controlled while maintaining the first positional relationship.

Abstract: A hydroponic cultivation apparatus includes: a growth tank in which a plant is grown; an air blower which supplies wind; and an air blowing pipe which guides the wind sent from the air blower to the plant. The air blowing pipe includes a first pipe and a second pipe which extend in the same virtual line, and each of the first pipe and the second pipe is provided with a plurality of air outlet holes in a pipe longitudinal direction and supplies the wind from the air outlet holes to the plant. The air blower supplies the wind such that a direction of the wind inside the first pipe and a direction of the wind inside the second pipe are opposite directions.
