  1. Find the value of the cut \(\{ A , C , D , G , H \} \{ B , E , F , I \}\) 2
  2. Write down a cut with a value of \(300 \mathrm {~m} ^ { 3 } \mathrm {~s} ^ { - 1 }\) 2
  3. Using the values from part (a) and part (b), state what can be deduced about the maximum flow through the network. Fully justify your answer.
