Directions: Select the most appropriate fillers for the blanks such that the sentence makes coherent sense.

After an absence of 30 years, I decided to visit my old school again, where I had __________ to find changes but not a _____________ different building.

For the first blank, as speaker is visiting his school after 30 years, so he cannot know but expect, imagine, hope, or anticipate to find changes at that place. For the second blank, 'entirely' can't be used as it should be preceded by 'an', and not 'a' as given; hence, ruled out. 'Very' and 'single' are not that suited for the blank; therefore, ruled out. 'Completely' on replacing the blank gives a cogent meaning to the sentence. Hence, option (4) is the correct answer.
