What is the part of the mosque that faces east to mecca called not the prayer hall the thing that shows you where to face plus why are we allowed no punctuation other than 1 question mark?

It is called the qiblah, and only points east in places west of Mecca. Places east of Mecca have the qiblah on the west side, south of Mecca point to the north, etc., etc.

As for the punctuation question, I have no idea. I guess they don't want you to use profanity, so they limit all punctuation to a question mark.
