Reasonable.

If the social science fund is not used up at the end of the project, it will be recovered. There should not be too much remaining funds for the project, which means that the budget is unreasonable. Although it will not affect the completion of the project, it may have some disadvantages in the future.

For example, if the school has more than a year left, it must be used up, otherwise it will be taken back. For 863 or other vertical subjects, the remaining funds will be recovered no matter how much they are.
