Read the passage given below and answer the questions that follow.

Let $\alpha,\beta$ and $\gamma$ be real numbers such that the system of linear equations $$x+2y+3z=\alpha$$ $$4x+5y+6z=\beta$$ $$7x+8y+9z=\gamma-1$$ is consistent. Let $|M|$ represent the determinant of the matrix $$M=\begin{bmatrix}\alpha&2&\gamma\\ \beta&1&0\\ -1&0&1\end{bmatrix}$$ Let $P$ be the plane containing all those $(\alpha,\beta,\gamma)$ for which the above system of linear equations is consistent, and $D$ be the square of the distance of the point $(0,1,0)$ from the plane $P$.

IIT-JEE 2004Question 414
$P_1$ and $P_2$ are planes passing through the origin. $L_1$ and $L_2$ are two lines on $P_1$ and $P_2$ respectively such that their intersection is the origin. Show that there exist points $A,B,C$, whose permutation $A',B',C'$ can be chosen such that (i) $A$ is on $L_1$, $B$ on $P_1$ but not on $L_1$ and $C$ not on $P_1$; (ii) $A'$ is on $L_2$, $B'$ on $P_2$ but not on $L_2$ and $C'$ not on $P_2$.
