this is what the response draft question was we had to answer:

Descartes goes through quite a bit of trouble convincing himself to adopt a fairly radical sort of skepticism in Meditation I. Over the course of the remaining Meditations, he attempts to work back from that skepticism to a firm foundation that he can be certain of and avoid the risk of error moving forward. He argues the he can be certain of his own existence, that he is a thinking thing, for God’s existence as an infinite substance, and finally, in Meditations V-VI, for material things (including his own body).

In your judgment, does Descartes adhere to his own standards of certainty beyond any possible doubt throughout the Meditations? If so, walk your reader through a sketch of the arguments he offers and explain why each step is sound. If not, identify where he seems to be abandoning his own standard and why he should not be permitted to make the step in question.
