Aclaim is a statement that must be arguable detailed positive factual

A claim is a statement that must be arguable.

There must be at least two sides to a claim. For example, I can claim that I am the best person in the world (not that I am). Others can either:

1) support me, and be on my side

2) argue against my claim, and point out my faults.

hope this helps

remember, the goal of an adjective clause is to add more information to a noun or a pronoun. as you can see from the examples above, you can add information by including a longer adjective clause or tighten up a sentence by turning the adjective clause into an adjective phrase.
