Marcie is a student in your fifth-grade class, and her best friend tara is in the classroom directly across the hall from yours. marcie often gets up and goes to the doorway to ostensibly use the pencil sharpener, which is located near the door, or to throw something away in the garbage can (also located near the door), but you know she's hoping to catch a glimpse of tara. you suspect that tara is doing the same thing in her room, because you see her at the classroom door frequently. knowing what you know about marcie and tara, which of the following actions on your part makes the most sense? a. visibility.
b. accessibility.
c. distractibility.
d. differentiation.
