I am not sure if my reasoning is correct for this one because a lot of the answer choices seemed attractive.
My pre-phase was the illusion of direct knowledge stems from the fact that we become experts like chess players.
A) Ignoring feedback was never mentioned unless some inference on ignoring feedback can be drawn.
B)All looks good but overlooking instances was not mentioned unless some inference can be drawn regarding this
C)Seems pretty close to the passage. The passage's discussion on being experts did talk about how the expertise means we change our perception towards the subject without really noticing it ( see the quoted lines below)
D) I think this statement is true but is not the reason why we have illusions of direct knowledge.
E) This seems attractive in that in plays on the fact that maybe our thought process is not all that precise. Regardless, the passage does not say it is because of uncertain internal thoughts that creates the illusion of non-inferential thought. IF anything it is because of our sheer certainity that creates the illusion. The sheer certainty has some support in lines 54-56
Actual Answer from the Text: Line 35-40 and Line 52 to 54. In the 35-40 section it says "we fail to notice we are making them [inferences]" because we are experts. In the Line 52 to 54 it affirms it is the "frequent occurrence " of our activities that creates this illusion.
Hence between C and D even though I personally do not know why D is wrong C is a closer fit, especially to Lines 35-40
