Question

which sentence should be removed from paragraph 2 to improve the flow?
a. it was originally meant to be a bell tower for a cathedral
b. many cathedrals were built in europe around this time
c. the original architect of the tower is presumed to be bonanno pisano
d. it was built with limestone and lime mortar, which has helped the tower to remain standing despite its tilt.

Explanation:

Paragraph 2 focuses on the origin, construction material, and early structural issue of the Leaning Tower of Pisa. Sentence A repeats information from sentence 5, sentence C repeats sentence 4, and sentence D repeats sentence 7. Only sentence B is irrelevant to the specific details of the tower, as it makes a general statement about European cathedrals that does not contribute to the flow of the paragraph about the Pisa tower.

Answer:

B. Many cathedrals were built in Europe around this time.
