Based on the following passage, where would you be most likely to find Fourcault glass? Float glass, perfected in the 1950s, has become standard in buildings today. It improves upon the imperfections of the Fourcault process because it creates a product of uniform thickness with no optical distortion.

Float glass became the standard in buildings only after it was perfected in the 1950s, replacing glass made by the less uniform Fourcault process. A historic bungalow is the choice most likely to predate that change, so it is the most likely place to find Fourcault glass. The other choices are more likely to use modern float glass.
