Question: Great. I need to know which first name of the instructor goes with each class and class description.
SQL: SELECT T2.emp_fname , T3.crs_description FROM CLASS AS T1 JOIN employee AS T2 ON T1.prof_num   =   T2.emp_num JOIN course AS T3 ON T1.crs_code   =   T3.crs_code JOIN professor AS T4 ON T2.emp_num   =   T4.emp_num
