Answer:
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.
