The only possibilities **for a and** c are 3 and 1, since 3 is prime. An example is the skillful way in which his terrier Tony opened the garden gate, easily misunderstood as an insightful act by someone seeing the final behaviour. Please try again later.

Lloyd Morgan after trying out similar phrases "trial and failure" and "trial and practice".[3] Under Morgan's Canon, animal behaviour should be explained in the simplest possible way. We may check **these solutions by plugging them back** into the original equation.
