Question: Please list the IDs of the advisors of the students who are in the 5th year of their program.
Evidence: IDs of the advisors refers to p_id_dummy; in the 5th year of their program refers to yearsInProgram = 'Year_5'

SQL:
SELECT T1.p_id_dummy FROM advisedBy AS T1 INNER JOIN person AS T2 ON T1.p_id = T2.p_id WHERE T2.yearsInProgram = 'Year_5'
