**Problem Statement:**

Let \( L_1 \) be the line passing through the point \( P_1(-3, 1, -2) \) with direction vector \( \mathbf{d} = [0, -1, 2]^T \), and let \( L_2 \) be the line passing through the point \( P_2(3, 5, -5) \) with the same direction vector.

Find the shortest distance \( d \) between these two lines, and find a point \( Q_1 \) on \( L_1 \) and a point \( Q_2 \) on \( L_2 \) so that \( d(Q_1, Q_2) = d \). Use the square root symbol ‘\(\sqrt{}\)’ where needed to give an exact value for your answer.

**Solution:**

- Shortest distance, \( d \): 
  \[
  d = 0
  \]

- Point \( Q_1 \) on \( L_1 \):
  \[
  Q_1 = (0, 0, 0)
  \]

- Point \( Q_2 \) on \( L_2 \):
  \[
  Q_2 = (0, 0, 0)
  \]
