A speaker addresses a person for various reasons. For example, s/he may see that the listener is distracted and s/he may want the addressee to focus more on what s/he has to say. Moreover, it can happen in the middle of a speech, because what will follow is really important and s/he feels the need to underline it by asking for more attention from the listeners. Furthermore, the speaker may address a person because s/he may want to talk specifically to this person about something or in order to give him/her the stand.
So, from all the above, it could be concluded that the basic request of the speaker when s/he addresses a person is to grab the listener's attention.
The answer would be D, it is half of what it was before.
The first one is correct. "It is like" the best decision you can ever make.
Saying it that way, is the same as saying that it would be the best decision that you can ever make, but adding more to it. Almost as if soeaking to someone who is overdramatic, and constantly say the word like.
I hope this helps
I would say D. Because authors always try and make their characters have a strong and unique voice to make their writing piece more comforting or relatable
