(Vocabulary) I can't find correct answers

6=Prolonged
9=Surge
10=Emulate
11=Renowned (renowned meaning well known)
12=Prospect (prospect being another word for hope)

This leaves #15 to you (note: add the letter d to the word).

Additionally be aware of your spelling error for #16. Also note that you have an incorrect response to #19. Well, that means you now have 2 words to figure out-use your dictionary!

(There may be other errors, however, you need to take out a dictionary and look up the words which have been given for the fill-in-the-blanks test.)
