need help, explanation with diagram please

Use the empty boxes drawn below to arrange the following tasks in an order that fulfills the process description below. Label each box and draw ALL connecting arrows. Process Description: There are eleven (11) Tasks to this process. There are twelve (12) boxes drawn below for your use, however, you will only use eleven (11) of the boxes below. Place an " X " across the one (1) boX you do NOT use. Use following Tasks and their relationships to mark-up the process. Use the empty boxes drawn below to arrange the following tasks in an order that fulfills the process description below. Label each box and draw ALL connecting arrows. Process Description: There are thirteen (13) Tasks to this process. There are eighteen (18) boxes drawn below for your use, however, you will only use thirteen (13) of the boxes below. Place an " X " across the boxes you do NOT use. Use following Tasks and their relationships to mark-up the process. Using the data and process map you created for Problem 2 (prior page), calculate how long (duration) it will take to complete the entire project. To do this, you will need to look at every possible sequence of tasks in the process and calculate which sequence takes the most time (in days). This will be called the "Critical Path". The following diagram has eight (8) blank rows, however, you may not need to use all of the rows. The first row provides an example sequence (or path)
