So confused on this sentence comp..

<p>After David left him waiting for the third consecutive time, Kirk realized that the same behavior he had initially valued as spontaneous and carefree was, in fact, simply ______
So we are looking for an opposite word of carefree and spontaneous
The choices are
A. capricious (this is synonymous with spontaneous so its out)
B. Incontrovertible (makes no sense)
C. extraneous (means something external or extra... not making sense)
D. captivating (something that makes you.. i don't know how to describe but I know its not this)
E. inscrutable (I know this meant inpenetrable.. which once agian makes no sense...)
So which one is it
extraneous? It kind of makes sense i guess. I can't check answers right now thats why.
NM i just remembered. Extraneous means irrelevance which makes sense.</p>

<p>collegeboard's explanation:</p>

<p>Choice (A) is correct. “Capricious” means irresponsibly unpredictable. If one were to insert this term into the text, the sentence would read “After David left him waiting for the third consecutive time, Kirk realized that the same behavior he had initially valued as spontaneous and carefree was, in fact, simply capricious.” The phrase “initially valued” suggests that after being left waiting three times in a row, Kirk changed his opinion of David’s behavior. It would make sense to say that Kirk would no longer value David’s behavior if he came to see it as “capricious,” or irresponsibly unpredictable.</p>
