In my understanding, the way this works, is that there is a protein in dry beans that serve as a protection against the bean being eaten by animals, so that it can remain a seed and grow more beans. When the bean is soaked, and begins to sprout, that protein is activated, and it is undigestable to animals, who learn don't eat that thing. By providing an enzyme that either converts starch to sugar, or by fermentation (converting sugar to alcohol), that protein can be pre-digested, to make it digestable by humans.

or getting financing. There are different types of contingent statuses. For example, Contingent - Show means that it is still possible to tour the property and submit a backup offer in case the current one falls through. Contingent - No Show indicates that the seller no longer wishes to show the property. Contingent with Kick-out means that the seller is willing to accept a better offer if one comes along and may kick out the current offer.
