Which questions should a writer ask when revising an argumentative essay to make sure it is in a formal style?

check all that apply.
are my ideas logically connected?
are my arguments well organized?
do i avoid a casual style and tone?
where can i insert some contractions?
which wording should be more colorful?

The answers are:

Are my ideas logically connected?

Are my arguments well organized?

Do I avoid a casual style and tone?

An argumentative essay, like any other piece of formal writing, should try to avoid a casual tone, sticking instead to a formal tone; that is to say, a form of expression that is concise, accurate, meaningful, and avoids the ambiguities of a casual tone. A final revision should also contemplate the first two answers, and one of the best ways to do this is to read the essay aloud or have someone read it aloud since listening, rather than reading, can more clearly reveal if the ideas are logically connected and well organized.  

different routes can lead to sammy to different places, with different roads.   if you check a map, you can see the routes.   try to make connections of the places and count how many there are.   hope this : )
