Final answer:
Hal's statement about his friend Kal's cold is an example of the Just-World Hypothesis, where he implies Kal's actions led to his illness.
Step-by-step explanation:
When Hal suggests that Kal caught a cold because of not wearing a hat and not taking vitamins, Hal is demonstrating the Just-World Hypothesis. This hypothesis is the belief that good things happen to good people and bad things happen to bad people, and people get what they deserve. In this scenario, Hal implies that Kal's cold is a direct consequence of his actions (or lack thereof), which aligns with the Just-World Hypothesis rather than the other biases or fallacies.
