Answer 2

The statement that arches are structures used to span spaces and support the weight above it is true.  These structures are curved members that are used to span an opening and to support loads from above.

Arches were known in ancient Egypt and Greece but were considered unsuitable for monumental architecture. The Romans, on the other hand, used arches in bridges, aqueducts, and large-scale architecture.
