Answer to Question 1

ANS: B
This question involves the Venturi principle, which states that the pressure drop caused by fluid flowing through a tubular constriction can be restored to preconstriction values by allowing for a gradual dilation in the tube.

Answer to Question 2

ANS: C
As fluid approaches a constriction in a tube, the flow of the liquid will accelerate (increase) as it enters the constriction, which in turn causes a decrease in lateral-wall pressure.
