On the surface, what seemed most appropriate was the idea that one possessed for the problem.
Certainly, one needed to consider another possibility that might exist within oneself when facing the problem, thus understanding it.
Then further explanation and clarification became the most fitting for one's satisfying cognition of the problem.
Subsequent actions, however, might again elicit another understanding or doubt that people could grasp.
On the surface, what appeared to be very nice, agreeable, was facing more ideas about the matter that arose in one's own mind.
The need for explanations ceased to exist, as what seemed very nice became clear, and natural pondering no longer involved more doubt.
On the surface, the difficulty or ease of acceptance, or rather a very clear attitude that one had towards the problem.
Those situations on the surface seemed to have the most fitting handling of the problem, which looked to be the best.
