Can you help me solve this problem...

1. Calculate the ES/EF (Forward Pass) for each of the activities above. (Activity H has already been calculated)
2. Calculate the LS/LF (Backward Pass) for each of the activities above.
3. Calculate the slack or float in each of the non-critical path tasks.
4. What is the Critical Path?
