It means that you are essentially a historian. You look at the past to figure out things, that way people can lake the future better.
        
                    
             
        
        
        
It is an Adverb. Adverb modifies and functions like an adjective.
        
             
        
        
        
It all depends on one's confidence and way of expressing themselves. Personally, I would say no. After everything that's been going on in this horrid year of 2020, the BLM movement has reasons. Since society today <em>still</em> has to fight for black lives (as well as others that aren't cis, straight, white men), the Pledge of Allegince speaks lies. Many people may pledge "justice for all," but our actions speak different from our words. If you are safe and have the confidence to rebel for what is just, <em>do not stand</em>, as one with heart shall not stand for injustice.
Hope this helps!
I absolutely love writing stuff like this, and it feels good.
 
        
             
        
        
        
You can. If I were you, I would try to use your character inner thoughts to try and start it off. You can do that by using italics. Here's an example:
(Based on a different show, Riverdale. I'm using the last sentence from your story to show you how it would work)
(...) I tried getting my arm free from underneath the bed. As I pulled, I was able to get my hand out. I was appalled, but grateful.
<em>How did that happen? </em>Betty thought to herself as she shook her head.
I hope you undertood that and that it helps.
 
        
             
        
        
        
Answer:
Explanation:
1. I will first Identify the claim. The claim is sometimes stated in a very general way, then elaborated on throughout the essay. 
2. I will next examine the claim for qualifiers; words like "some," "many," "most of the time," etc. It can sometimes be damaging to an argument to omit qualifiers, particularly if there are also no exceptions provided. It is up to you as a reader to determine whether the writer's unqualified claim is damaging to this particular argument. 
3. I will then examine the claim for an exception. After looking for qualifying words in the claim, the next step is to determine what the writer considers to be the situations in which the writer's claim doesn't apply. In other words, it is necessary to identify any exceptions the writer makes to her claim.
