Which circumstances is most likely to cause a farmer to store soybeans for future sale instead of selling them right after harvest?

The government lifts restrictions on the importation of soybeans.

Explanation:

The most likely reason why a farmer might not want to sell his beans right after harvest, and would instead want to store them for future sale would be if the government lifts restrictions on the importation of soybeans. This would mean that soybeans can be brought into the country from abroad. It is likely that these imported beans are cheaper than the ones the farmer produces, which means he might be unable to sell as many as he expected.
