Which of these is an experimental type of romanesque architecture? a. ribbed domes b. ribbed arches c. ribbed vaults d. all of these above

The correct choice would be the third answer.

Letter C.

The correct answer is C., ribbed vaults are an experimental type of Romanesque arquitecture. Ribbed vaults became popular in the 12th century, but they faced a lot of structural problems. Ribs were used both transversally and diagonally, but, because arches were mostly semicircular, de difference in length between the ribs was significant. Builders had to experiment with different solutions to fix the problem.

im not sure but i have a question for you?

abraham was promised great blessings by god, both to himself and his family, including all of his descendants. those blessings are called the abrahamic covenant.

the abrahamic covenant bible story has three main features:

1. the promised land of canaan (gen 12: 1) (gen 15: 7).

2. the promise of offspring to a 75-year-old childless abraham (genesis 12: 2) (gen 15: 4-6) (gen 17: 6-8).

3. the promise of blessings and redemption to abraham and the families of the earth through him. (genesis 12: 3).

finally, god gave abraham the rite of circumcision as the specific sign of the abrahamic covenant (genesis 17: 9–14).
