Answer:
external
Step-by-step explanation:
According to psychology, when a person has an external locus of control they tend to believe that their successes or failures come from external factors that they cannot control. In other words, events are caused by external factors out of their control.
In this example, Achak flunked his midterm, he things that this is his teacher's fault and "it's all their fault" is a commonly heard phrase from Achak. We can see that Achak believes that his failure is caused by external factors out of his control, like his teacher or other people. Therefore, this is an example of external locus of control.
