Hi!
Your answer is C.
A is <u>NOT</u> correct because most times you will not have a dictionary nearby, therefore you don't want to skip every unknown word you come across. It could confuse you as a reader.
B is <u>NOT</u> correct because it is not the best answer. You might have written it down on your running list, but you still don't want to simply skip the word. Again, it may confuse you as a reader without that word.
C <u>IS</u> correct because you want to understand the passage you are reading. If it is clear without knowing the word, you can infer what the word means and you can keep on reading, because you know what the passage was about.
D is <u>NOT</u> correct because it does not matter if it was a quote spoken by a character; you still want to understand what you're reading, right? Being spoken by a character is no reason to skip a word.
