Question

1. the large, open spaces in gothic cathedrals were made possible by the use of:

a. ribbed vaults and flying buttresses
b. reinforced concrete
c. solid stone walls
d. wooden beams

Explanation:

To determine the correct answer, we analyze each option:

• Option a: Ribbed vaults and flying buttresses are key architectural features of Gothic cathedrals. Ribbed vaults distribute weight efficiently, and flying buttresses transfer the weight of the roof and walls to external supports, allowing for large, open interior spaces.
• Option b: Reinforced concrete is a modern building material, not used in Gothic cathedrals.
• Option c: Solid stone walls would be too heavy and would not allow for large, open spaces; they were a feature of earlier Romanesque architecture.
• Option d: Wooden beams were used in earlier architectural styles but are not associated with the large, open spaces of Gothic cathedrals.

Answer:

a. Ribbed vaults and flying buttresses
