Question

if a back entry door is left open to remove heat from a kitchen, what must be in the doors place? a tight - fitting screen door. something to keep the door propped open a bamboo curtain none of the above

Explanation:

When a back - entry door is left open to remove heat from a kitchen, a tight - fitting screen door is a good option. A tight - fitting screen door allows for ventilation (to remove heat) while also keeping insects out. A bamboo curtain may not provide as effective a barrier against insects as a screen door. Just keeping the door propped open (option B) doesn't address the insect - prevention aspect as well as a screen door.

Answer:

A. A tight - fitting screen door
