Reаd the pаrаgraph. Chооse the best answer tо the question. The physical environment of a classroom is extremely important because it can influence the way teachers and students feel, think, and behave. If a student feels pressured, under stress, unhappy, or unsafe, it will be impossible for her or him to learn the lessons planned by the educator. Likewise, if a teacher feels unhappy or disorganized because of the classroom's lack of order or detail, the ability for her to teach is greatly diminished. The environment of a classroom serves four basic functions: security, social contact, pleasure, and growth. For real learning and teaching to take place, all four of those needs must be met by the class space although not necessarily in equal amounts.
