Read the following passage, then answer the question.
The inspector arrived at the mill on a Tuesday, clipboard in hand, moving through the floor with the practiced calm of someone who had seen worse. He noted the heat first—not the kind that comes from summer but the kind that presses down from machines and never lifts. The foreman walked beside him, pointing to the newer equipment, the ventilation upgrade from last spring, the safety log hung neatly by the door. The inspector wrote steadily. When he reached the far end of the floor, where the youngest workers sorted scraps in a corner without windows, he paused. He wrote something, then crossed it out. The foreman did not follow him there.
13.
The inspector's act of crossing something out in his notes most strongly suggests a structural parallel to which concept from informational writing?
a.
Proportionality, because the inspector gives balanced attention to all parts of the floor
b.
Refinement, because the meaning of the inspector's role changes across the passage
c.
Signposting, because the crossed-out note marks a shift in the argument
d.
Burying counterevidence, because a complicating observation is quietly removed from the record
