Aslam, a 12-year-old, gets too tired by evening to complete his homework. This is because he goes off for football training soon after school. The school counsellor advised Aslam to reduce his football training time and increase his weekend practice time. This way, Aslam will not be too tired and will be able to complete his homework. Identify the antecedent operation:

Reduce his football training time on weekdays

The correct answer is Option (3) → Reduce his football training time on weekdays

In this scenario, the school counsellor's advice to reduce training time during the week is the antecedent operation. An antecedent operation is a change made to the environment or a specific condition that occurs before a behavior to alter its probability. By reducing the football training time, the counsellor is changing the condition (less fatigue) to increase the likelihood of the desired behavior (completing homework).
