The "Easy Way Out"

Claudia, Ben, Mary and I all attended Humber College together. We got together for coffee last week to catch up. Reminiscing our college days, we laughed about how the other students said we were taking "the easy way out" because we all took business programs.

After we all left, I was trying to remember everyone's last names, programs they were enrolled in, favourite courses, and the length of their programs. Based on what I remembered, can you help me figure out all the details?

First Names: Ben, Caterina, Mary

Last Names: Delco, Thompson, Adecco

Programs: Business Admin, Business Management, Marketing

Favourite Subjects: Business Law, Accounting, Microeconomics

Program Lengths (Yrs): 2, 3, 4

Clues:
1. Caterina felt that her accounting skills would help her run her own business after graduation.
2. The student who liked Law was in school longer than the student who likes Accounting.
3. The Marketing student was not Mary.
4. Mr. Delco's favourite subject was not Accounting.
5. The three graduates were (in increasing order of program length) the Business Management graduate, the student who liked law, and Thompson.
