Answer:
The question is incomplete, but I guess its about variable and fixed inputs. In this case, Van's workers are considered the variable input since Van can hire or fire workers in the short run. While the ovens are fixed inputs, since Van cannot change the number of ovens due to space and legal limitations (lease contract).
The short run or the long run are not specific time frames, it is not like current or non-current assets or liabilities. The short run refers to a time period where a business can only change certain inputs, e.g. labor or hours worked. While the long run refers to a time period where a business can change all of its inputs. I.e. in the long run, all costs are variable.
E.g. If Van's lease contracts (restaurant and ovens) expired in 6 months, and he was then able to get a new place and enter new contracts, then the long run would be in 6 months. But under the current conditions, the long run is 4 years since that is when the lease contracts expire.
