Let \( ABCDV \) be a rectangle based-pyramid, where \( V \) is its apex, and let \( XY \) be a line where:
\begin{align*}
X&\text{ lays on the side }AV\text{ and }|AX|=|XV|,\\
Y&\text{ lays on a ray }DC\text{ and }|DY|=1.5|DC|
\end{align*}
(see the picture). The points of intersection of the line \( XY \) with the surface of the pyramid are:
the point \( X \) and a point on the pyramid face \( BCV \)
the point \( X \) and a point on the pyramid face \( DCV \)
the point \( X \) and a point on the pyramid edge \( CV \)
the point \( X \) only
