I haven't seen this before but by looking at this can be make out that there will be more than 1 critical path - so not good for the project.
There are 3 task as start activity with different duration - and overlapping each other and same goes for end activity as well.

For this question, you need to first draw the network diagram and then calculate critical path. As we don't know the type of dependencies(SS,SF, FS, FF), don't get into the details and also this info is not required to solve this question.

For some reason, I'm unable to attach the critical path image, so here is the calculation

Length of different paths
start->1->2->end = 10 months
start->3->5->end = 11 months
start->4->5->end = 12 months

so critical path = start->4->5->end = 12 months
