Consider a system that categorizes job applicants based on their cumulative work experience according to the following categories: • If work experience is between 0 to 1 year, the applicant is categorized as Entry-Level. • If work experience is between 2 to 3 years, the applicant is categorized as Junior. • If work experience is between 4 to 5 years, the applicant is categorized as Mid-Level. • If work experience is 6 years or more, the applicant is categorized as Senior. Assume that work experience is expressed in whole years. How many equivalence class partitions can be identified in this scenario?
