 Vallicella and others who pose the question in these terms make it clear that they are not after a causal story about how a particular lump of sugar or a particular black chair was made. Instead, what drives the problem as posed is the assumed contingent nature of the connection between constituents of states of affairs. This chair is black but it might have been some other color; and this blackness, for realists, need not be instantiated here, it might (and in fact is) present in many other states of affairs. So what is it that “makes it so” that this particular blackness and this particular chair are actually united? There is nothing in the natures of constituents of states of affairs to require that they come together, so—the thought is - something else must bring those constituents together.
