TO, IN ORDER TO, AND. Any difference? The usage of commas as well.

[Jesule]

Hello! How are you? Thanks in advance!

Can I use all of them and mean the same thing?


I shall open the box 'TO' see if it´s true what you´re saying.
I shall open the box 'IN ORDER TO' see if it´s true what you´re
saying
I shall open the box 'AND' see if it´s true what you´re saying.


2.- You don´t go to that club ´cause
the music played, you say, is too loud.


Is it correct to use that "you say" between
commas? We can use it in Spanish, but I don´t know if that´s correct
in English.


Thank you very much!
