Abstract
We show explicitly how the T model, E model, and Hilltop inflations are obtained from the general scalar-tensor theory of gravity with arbitrary conformal factors in the strong coupling limit. We argue that attractors can give any observables and by this method. The existence of attractors imposes a challenge to distinguish different models.
