Answer 1

I've edited the question to add code formatting; we can see the colour changes midway through Department's faculty office:

because the apostrophe is throwing it off. The same colour change happens in SWISH. As @brebs comments, things starting with a capital are Variables and must be wrapped in single quotes to be atoms. Ones with quotes used as apostrophes need to have the apostrophe escaped with a backslash:

verify('Department\'s faculty office')
