Read the following premise and answer if the hypothesis is true.
She didn't know if they had given themselves sufficient time to think things over before they married - that was the kind of question her sister Louise asked. Edward stayed in the Engineers for a bit, then came out and was not very successful in finding a job to suit him. That wasn't his fault and if anyone said that it was Nenna would still feel like poking a hole in them.
Hypothesis: it was Edward's fault. Is the answer "Yes", "No", or "It's impossible to say"? Respond with only the answer and no additional text.
No
It's impossible to say. The text does not provide enough information to determine if Edward's job struggles were his fault or not.
