Phil and Jenny want to start a support group for single parents. The local high school will provide space for the group to meet, free of any charge. However, only the main gymnasium will be available for their use. While it is a large space, there are no chairs or tables available. In addition, per school regulations, the gymnasium must remain unlocked and open to other persons during the time the group meets. What physical and or environmental factors could have a negative impact on the group's communication? What can Phil and Jenny do structure the environment to address or minimize the impact of these factors?
