Question: Find names of all students who took some course and the course description.
SQL: SELECT T1.stu_fname, T1.stu_lname, T4.crs_description FROM student AS T1 JOIN enroll AS T2 ON T1.stu_num = T2.stu_num JOIN CLASS AS T3 ON T2.class_code = T3.class_code JOIN course AS T4 ON T3.crs_code = T4.crs_code
