Um, no.

Here's a rule:  If Ralph is in his office, then Ralph is at MIT.
                    \                  /         \           /
                     \                /           \         /
                          Premise                 Conclusion
                        (Antecedent)             (Consequent)

We could make either part into a query:
       Is Ralph in his office?
       Is Ralph at MIT?

But it seems much more natural to think of the premise as a query; it
leads us to a very simple algorithm:

      query: Is Ralph in his office?
      on success: we can conclude Ralph is at MIT.
      on failure: we can't conclude anything from this.

How else do you see it?
