Please write one sql query for the following 5 question:

Print the name and department of each professor who has taught a course not from his/her department at least once Print the sid and name of each student who has earned a 3.5 or higher grade in at least two different courses. Print the name and age of the student (s) with the highest GPA in their exact age group (i.e., the name and age of the student (s) with the highest GPA among all 15 year olds, the name and age of the student(s) with the highest GPA among all 16 year olds, and so on), for ages less than or equal to 18 For each department that both (a) has the substring "Engineering" in its name (e.g., "Electrical Engineering") and (b) has at least 2 students majoring in the department, print the name of the department and the average GPA of the students who major in the department Some courses are popular among students just because students enrolled in those courses usually get good grades. Print the department name, course number and course enrollment of each course C such that the following two conditions hold: (1) course C's enrollment is at least 3% larger than the average enrollment of the courses offered by C's department, and (2) course C's average grade is at least 3% larger than the average grade obtained by students in the courses offered by C's department. Assume that the enrollment of a course is the sum of the enrollment of all its sections. You can completely ignore any course that has no students enrolled in it
