$12.$True or False: EFV distillation is particularly useful for predicting the yield of light distillates from crude oil, aiding in the logistical planning of refinery operations.

True or False: Atmospheric and vacuum distillation units are designed to operate independently, with no interdependence or sequential processing relationship between them.

True or False: The $5-95$ gap provides a measure of the volatility of crude oil, with a smaller gap indicating a more volatile and potentially hazardous crude.

True or False: The degree of difficulty of separation $($t$50)$ offers insights into the thermal stability of crude oil fractions, guiding the selection of appropriate processing temperatures.
