Would "What is the name of this square?" also be correct? If not, how would you ask that ?
It is correct and accepted. If you have a similar problem, use "My answer should be accepted".
Why isn't - What is the name of the square - marked correct? (what shows that this must be that square and not the square?)
There was a coding error in one of the translation groups, which has now been fixed. "What is the name of the square?" should be accepted in the future. Thanks for the tip!
