Answer: c. looked / was searching
Explanation:
<em>When I first got off the plane, I </em><em><u>looked</u></em><em> around as if in a fog. I </em><em><u>was searching</u></em><em> for my classmates. </em>
The sentence started with the past tense being used by the narrator. As such, the rest of the narration has to be in past tense as well.
With this in mind, the word <em>looked</em> and the phrase <em>was searching</em> would be the right words to use to fill in the blanks.
The answer is B) "<span>seen from a higher still, and the highest, who shall say what they are, or that they are worth looking at or thinking of at all?"
</span>
I am 100% sure because the THESAURUS of implicitly, not definition (because this is english) means completely, absolutely, totally, etc.
Also, the question states that 'implicitly argues that people need to think independently and QUESTION authority?" So, B is the only option that demonstrates that people need think independently. Plus, its the only option that has a QUESTION MARK!
