The ancient Greek theater of Epidaurus, constructed in the fourth century BCE, is renowned for its extraordinary acoustics. Performers on the open-air stage can be heard clearly by spectators seated in the top rows, some sixty meters away. For decades, researchers debated the mechanism behind this phenomenon. In 2007, acoustic experts discovered that the secret lies in the theater’s limestone seats. The theater, which could accommodate up to 14,000 spectators, was designed by the architect Polykleitos the Younger. The researchers found that the corrugated surface of the seats acts as a natural sound filter, reflecting high-frequency sounds—such as the actors' voices—toward the audience while absorbing low-frequency background noise like the rustle of wind and the murmur of the crowd.
The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?
- AKeep it, because it provides essential context about the size of the audience required to test the theater's acoustic properties.
- BKeep it, because it identifies the architect responsible for building the limestone seats described in the paragraph.
- Delete it, because it interrupts the explanation of the theater's acoustics with details about its seating capacity and architect.Cevap
- DDelete it, because it repeats information about the physical layout of the limestone seats that is explained later in the paragraph.
