Which statement best describes one way that Classical Greek sculpture influenced Roman sculptors?

Greek sculpture influenced the Romans from the 2nd century BC. Prominent 1st century BC and 1st century AD Romans such as Cicero and Pliny the Elder greatly admired the innovative work of classical Greek sculpture artists, such as Polykleitos. However, the Romans did not produce much sculpture based on the classical Greek model. Their sculpture was predominantly portraiture (see below) until , from the 1st century AD, the Romans adopted Hellenistic sculpture, which took sculpture to a different level, as a model for their own sculpture.

Prior to the influence of Greek sculpture, Roman sculpture was portraiture sculpture (busts). Their portraiture sculpture is regarded as the best sculpture of this kind ever produced.
