writing out factors to a situation

Hi,

I think when you are giving names of categories, parts, roles, or the likes of them, you are at liberty in terms of putting or not putting articles. Can 'factors' be one of them? I think it can. Can you say consistency needs to be followed for situations like those indicated? I am asking because this type writing is important to know.

Expanding on 'why'.

There are many factors: The parts of language (the speech rate [too fast/ slow], pausing [too much / little], ... , amount and organization of language, content, and context and kind of text.

My problem is this:

1) When you put 'the' as the first factor, could that mean a person meant to extend 'the' to others in the list? Obviously, 'pausing' need not have 'the', although there is no harm to have one; and that goes for the word 'amount' and the rest too, until you come to the word 'kind'. Until this word, all nouns, that are 'parts', 'pausing', 'amount', 'organization', 'content', and 'context', are fine to me because they are either uncountable or plurals, but the use of the word 'kind' is baffling because it stands out among the words that consistency prevails--unless 'the' is extended to it.

2) What is with the brackets? Are they used if one needs to expand on a content in parentheses?

Help if you could follow what I am saying. Thank you.
