Question 14
The original asks “Which two manhole covers are safer?” and shows A square, B circle, C triangle, D horizontal rectangle and E vertical rectangle. Discuss whether the pictures alone justify a unique pair or guarantee that a cover cannot fall through its opening. Give checked geometric examples. AI reconstruction: for the examples only, use rigid flat ideal covers and similar slightly smaller openings; no latch or special supporting mechanism is assumed. This is a geometry exercise, not practical safety advice.
