As many times as you want makes most sense to me but they all fit in the sentence
What are two reasons for versioning your still-life project file?
Answer: The first reason for versioning your still-life project file is because this way if by mistake or unfortunate circumstance your files does not open because it became corrupt you can recover the data from an old version file. The second reason is that you can manage to have multiple copies of it in case anything were to happen.
I hope it helps, Regards.
