The reason why "good vs. evil" is a universal theme is because there are always two forces at work one for good and one for evil and for every good/evil thing there is an evil/good thing that will go up against each other until the end of time or at least until one of them is defeated, but then another good/evil thing will appear to take it place. 
Example 1:
                Your in high school and there is a bully and you try to stop the bully from hurting others. This makes you the good force and the bully the evil force (he/she doesn't have to be "evil" per-say just bad or mean will do).
        
             
        
        
        
The central idea is the same as the main idea. Most of the time, the main idea is mentioned in the Title. Without reading the essay, I do not know what the central/main idea is.
        
             
        
        
        
Answer:
1. The author's argument is that evolutions in language such as "textspeak" do not ruin our language, rather, they are creative ways of incorporating symbols in technology.
2. The author claims that
a. Changes in language do not demonstrate decay, rather they indicate flexibility.
b. Emoticons are not just faces. They convey feelings.
c. The use of emoticons in language makes ideas to be better clarified. They ease the flow of conversations.
d. A symbol can communicate an entire message.
3. Reasons to support the claims
a. History shows that people have always complained about changes in language but time shows that these changes are not harmful but rather innovations.
b. Emoticons convey feelings of happiness, sadness, or anger during text communications. These symbols aid the flow of communication and clarifies ideas that would otherwise not be understood because the communicators cannot see each other physically.
Explanation:
In the article by Lauren Collister, she argues against the popular belief that emoticons are ruining language. She rather believes that these symbols are innovations that should be embraced by all because they ease the flow of communication. Dating back to A.D 63 when some Latin students began writing the French Language, a scholar tagged the language an "artificial language". Today, this is the language of an entire people.
 Innovations in language are to be embraced not rejected.
 
        
                    
             
        
        
        
Answer:
C). Life can be challenging, but sometimes dreams come true.
Explanation:
"Rickie Fowler Make-a-Wish and the walk a lifetime at Detroit golf" penned by Shawn Windsor explores the story of a young boy, Anthony Trudel, of 15 suffering from brain cancer and his immense love for golf. Rickie Fowler, one of the top fifteen PGA players, was Trudel's favorite player and he always dreamt of playing golf with him. Thus, the central idea of the story would be that 'life can be challenging, but sometimes the dreams come true' as, despite the illness, Trudel's dream of playing with his hero gets accomplished when he plays with him for a charity match. Hence, <u>option C</u> is the correct answer.
