Answer : "For centuries its architects have toiled".
The main idea of the poem entitled The Armenian Language is the Home of the Armenian, is about the comforts associated with home. Among the quotations that supports the main idea are "roof and wall and nourishment", "its cupboards full, lamps lit, ovens hot, and always rejuvenated, always old, it lasts." The only quotation that does not support its main idea is this, " For centuries its architects have toiled". It does not talk about comfort but on how architects get tired throughout the years.
