Arugument In Logos

I've chosen to talk about the topic a) Students should be allowed to set their own rules, using Logos.

   In my opinion, I believe that students should not be allowed to set their own rules. This is mainly due to the problems such a situation might cause. Firstly, students will tend to set rules that give them much freedom and liberty. They will end up setting rules that are not good for themselves, for example, allowing students to play handphone games during lessons. Another example would be giving the green light to using vulgarities whenever they want to. This would definitely have negative implications, as students will end up with poor character and discipline. We all agree than students are the leaders of tomorrow. If the leaders of tomorrow have poor discipline and character, the country will eventually turn chaotic. Hence students should not be allowed to set their own rules.

What is an exposition?

I've actually not much clue whether what my idea of exposition is correct. Anyways, here I go:

It is a writing or speech primarily intended to convey information or to explain. It is a good way to put across an arugment and convince the reader or listener about the author's view on a certain topic. Usually, I guess, a good exposition contains two sides of the issue. 

In an online dictionary, I found the following meaning for exposition:

1.a setting forth of the meaning or purpose (as of a writing)2. discourse or an example of it designed to convey information or explain what is difficult to understand
I think very much sums up what's an exposition. We all use exposition very often, I think, even the essays we write for SS and History are expositions!
