What is the first thing the reader should do to understand an unknown word?

check the meaning
memorize the word
predict the meaning
study the word closely

The correct answer is: check the meaning.

Explanation:

When we see an unknown word in one text, the first thing we should do is check the meaning of the word in a dictionary. After that, we should memorize the word and try to use it in a certain context, in order to make sure we understood its meaning.

When we are predicting the meaning of the word, we can often make a mistake, because some words and their meanings can be quite unpredictable or illogical if someone doesn't know the etymology of the word or doesn't understand the scope of its use.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
