Directions: Select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.

I have found it helpful to make a distinction between essential consciousness or “awareness” and ________ consciousness.

(1) This is correct as the author speaks of 'essential' consciousness. “Supplemental' consciousness provides the needed differentiation and 'extended' provides the similar word. (2) This is correct as the author speaks of 'essential' consciousness. “Extended' consciousness provides the relevant contrast and 'supplemental' provides the similar word. (3) This is incorrect as 'exacerbating' means 'aggravating', and the word does not fit in the sentence. (4) This is incorrect as 'exacting' would imply 'something difficult', which would not fit in the sentence. (5) This is incorrect simply because 'protracted' has a negative connotation, while 'extended' and 'stretched' do not. (6): This is incorrect simply because there is no matching word among the options.
