Final answer:
In classical architecture, the outer columns may be adjusted in spacing or thickness to create visual balance, not to serve as a reduced-width 'column border.'
Step-by-step explanation:
The statement provided by the student, describing a column border as an unused column with a significantly reduced width, is not accurate. Instead, what the student seems to be referring to is a technique known as entasis, which is an architectural feature seen in classical buildings such as Greek temples, where the outer columns are intentionally made to appear closer or slightly thicker to give a more balanced appearance.
Beth's observation about columns being closer to each other at the edges implies an understanding of this ancient technique. Similarly, Steven's comment provides more insight into why ancient architects might have chosen to create this visual effect. It's believed that outermost columns, described here as an 'orphan,' could be made closer to their adjacent columns to provide an illusion of structural stability and visual harmony.
