Answer:
The last one
"Summarizing explains all of the main ideas in a source while paraphrasing focuses on just a few sentences."
Explanation:
This is becuase the first options are false (I did process of elimination)
option 1- summarizing actually focuses only on the most important things being summarized, not the small deltails. for paraphrasing,,, let me give an example. if your paraphrasing the quote, "we can't see air" you would say "air is not visible". so your'e restating the statment or whatever you are paraphrasing, but in your own words.
option 2- Both paraphrasing <em>and</em> summarizing require you to write the idea in your own words.
option 3- everything about 3 looks correct to me :)
I hope this helped!!!
