It’s a CB releasted QAS exam, and yes, it is “incomplete”–Earl gives some reasons in the quote, then the narrator (Virgil) says “there were other reasons,” meaning that the reasons Earl gave weren’t all the reasons–in other words, his explanation was “incomplete.”
As always look for the BEST answer as in NOT being subject to personal interpretation. Ask yourself … why could ore would C be … wrong? It is clearly an answer that works in all cases. On the other hand, the other choices are debatable and questionable. You have to “stretch” the text to support the other choices.
An easy C on that one as the test writers added a huge “look here” when they included the word OTHER and suggested an answer that is INCOMPLETE.
A little thought usually helps. Read around the lines mentioned in the question and look for words such as “other,” as xiggi pointed out. Also, Virgil does not say or imply that Earl is narrow-minded. C must be the correct option.
This is an example of how personal filters affect critical reading scores. People see the word ‘sentimental’ and immediately, a judgment is formed; a button is pushed for them.
