Suppose you were hired by Turner Construction Company as a supervisor. Your first job was an assignment to finish building a 4 story apartment complex. You were given the following task table but the actual tasks were not listed because the original table had been lost in a fire. Since you're an expert, you can figure out what the original supervisor meant by each letter. Once that's done, you need to draw a graph for the table and discuss with your boss how long the job will take.

| G | 3 | D |
| H | 5 | D,E,F |
| I | 3 | G,H |

ii) How long will this job take?
iii) After studying the graph, you realize that G also has E as a prerequisite, how does this change your time frame?
