Today's SAT question has underlined portions of a sentence to check for errors. Adding to the mystery of what to notice is the fact that you are asked if changing one of the underlined portion will improve the sentence. Therefore, you know that the underlined portion may be correct all by itself--but it may need a change to correct the sentence.
The only way to do this is to read the sentence noting what could be the question (the dual role of reading and evaluating): INotice whether the sentence is a complete sentence (not a fragment), whether the sentence is a run-on (using a comma where a semicolon or period is necessary to divide into 2 sentences), whether there is subject-verb disagreement, pronoun-antecedent disagreement. In short, watch for the predictable errors that SAT sentence errors include.
There are none. This takes LESS THAN A MINUTE.
Mark: No error. Glance over it again as a whole sentence, reading for comprehension. No error. Mark it and Move on.
This is our patent ROCKETCAT RACECAR strategy. You read it forwards. You find the answer and mark it. You speed backwards to eliminate the other possibilities. (Racecar is the same word read backwards. It is a palindrome.)
You have this point. Move on.
