$5.$True or False: EFV distillation is used to estimate the maximum yield of distillates from a crude oil, and it closely mimics the conditions in an actual refinery.

True or False: Atmospheric distillation operates at pressures significantly above atmospheric pressure to increase the efficiency of separation, and vacuum distillation follows to process residues.

True or False: The $5-95$ gap is used to assess the quality of crude oil, with a narrower gap indicating a higher quality and easier$-$to$-$refine crude.

True or False: The degree of difficulty of separation $($t$50)$ helps in determining the optimal feed rate for distillation columns, and a lower value indicates a need for slower processing.
