Question

what is the primary benefit to construction using ferroconcrete?
a. ferroconcrete minimizes the land needed for the structure.
b. ferroconcrete is the most cost effective material available in construction.
c. ferroconcrete uses both h - beams and i - beams so that it is almost indestructible.
d. ferroconcrete ensures the building will be strong and long - lasting.
please select the best answer from the choices provided
a
b
c
d

Explanation:

• Option A: Ferroconcrete doesn't primarily minimize land use; land use is more about design/layout, not the material's main benefit.
• Option B: It's not the most cost - effective material (e.g., cheaper alternatives like plain concrete for some uses, or wood in certain contexts exist).
• Option C: Ferroconcrete (reinforced concrete) uses steel reinforcement (not specifically H - beams and I - beams in the way described, and “almost indestructible” is an overstatement).
• Option D: Ferroconcrete (reinforced concrete) combines the strength of concrete (compression) and steel (tension), making buildings strong and durable, which is its primary benefit.

Answer:

D. Ferroconcrete ensures the building will be strong and long - lasting.
