Project Management- What is the critical path according to the original statements of precedence

HMS PinaforePlease focus on the following questions.1. What is the critical path according to the original statements of precedenceconstraints?2. What activities are worthwhile to consider for crashing?3. What logical inconsistencies may be contained in the statement of theprecedent constraints? That is, can the order of certain tasks bere-sequenced in order to reduce the makespan?MS Bicycle:Please focus on the following questions:1. What is the critical path according to the original statement of precedenceconstraints?2. Propose an alternate sequence of tasks that is logical and shrinks the criticalpath. What is the revised critical path? Does it achieve a makespan of 23 days orless?3. Justify using the optimistic times for solving for the critical path. You canassume that the optimistic times are the task duration times associated withcrashing each task to its fullest.4. Propose a contingency plan that the project managers should haveimplemented at the onset of the project that could have alleviated the currentstress.
