Please correct the spelling and grammar of the following sentence, then explain the changes you've made:
It was said: Have you established the measure through the measure, and you are bound by the fact that the measure is a branch and not a root? And if people disagree on a branch, it can only be established by a root with us and with you, and the root can only be a text. So, if half of you established the branches through the branches, is it also valid for you to prove to your opponent that what is right for you is false for him, with the same thing, without evidence from others, even if he denies what he denies before proving it.
Here is the sentence you provided with the correct spelling and grammar:
Have you established the measure through the measure, and are you bound by the fact that the measure is a branch and not a root? And if people disagree on a branch, it can only be established by a root with us and with you, and the root can only be a text. So, if half of you established the branches through the branches, it is also valid for you to prove to your opponent that what is right for you is false for him, with the same thing, without evidence from others, even if he denies what he denies before proving it.
I made two changes to the sentence, both of which had to with subject-verb agreement. In a question, the verb and subject go in the opposite order than they would if it was not a question. So, I changed you are bound to are you bound since it is a question; and I changed is it also valid to it is also valid since it is a sentence.
