Variable 'testProblemBases' Already Defined: Error Resolution Guide

This error message means that you are trying to define a variable named "testProblemBases" in a scope where it has already been defined. \n\nIn most programming languages, you cannot define multiple variables with the same name in the same scope. This is because variables are used to store values and if there were multiple variables with the same name, it would be ambiguous which value should be used.\n\nTo fix this error, you need to either remove the previous definition of "testProblemBases" or give the new variable a different name.
