Tips for Answering 
Do not merely try to consider each possible combination of answers; doing so will take too long 
and is open to error. Instead, try to analyze the passage in the following way: 
•
Read through the passage to get an overall sense of it.
•
Identify words or phrases that seem particularly significant, either because they emphasize
the structure of the passage (words like 
although
or 
moreover
) or because they are central
to understanding what the passage is about.
•
Try to fill in the blanks with words or phrases that seem to complete the sentence, then see
if similar words are offered among the answer choices.
•
Do not assume that the first blank is the one that should be filled first; perhaps one of the
other blanks is easier to fill first. Select your choice for that blank, and then see whether you
can complete another blank. If none of the choices for the other blank seem to make sense,
go back and reconsider your first selection.
•
When you have made your selection for each blank, check to make sure the passage is
logically, grammatically and stylistically coherent.
