Answer to Question 1

The clarity comes from the ability of light to pass through the material unimpeded by any internal barriers. Crystal polystyrene has no crystalline structure to interfere with the passage of light

Answer to Question 2

Clarity comes only if light transmission is unimpeded in passing through the plastic. ABS is usually multiplastic and so every phase boundary is a potential light-scattering location. Hence, ABS is generally opaque.
