Which is the best strategy for determining the meaning of a word in context?
a) see how many times the word is used in the passage.
b) use a similar sounding word in its place and see if it makes sense.
c) use the sentences around the unknown word to determine what it might mean.
d) realize that the meaning of the word is not necessary for understanding the passage.

While there are many strategies that can work, the BEST strategy is to C, use the sentences around the unknown word to determine what it might mean.  This is also the same strategy you use when you look up the work in the dictionary.  Often, the word has more than one definition.  In order to choose the correct definition, you must read the sentences around it to determine which definition is right.
