Final answer:
Pablo's incredulous look indicates he was feeling disbelieving. This expression conveys disbelief rather than anger, confusion, or joy.
Step-by-step explanation:
The question asks for the emotion that Pablo was feeling when he had an incredulous look on his face. Based on the description, the look of incredulity indicates a feeling of disbelief. In the context of facial expressions and emotions, an incredulous look does not generally convey anger, confusion, or joy, which eliminates options a), c), and d). Therefore, the correct answer is b) disbelieving.
Emotions can be complex and are often conveyed through a combination of facial expressions, gestures, and actions. For example, a smile of pleasure on an artist's face upon viewing their work indicates satisfaction and pride in their creation, whereas a faint smile of bewilderment might suggest confusion or mild surprise. Similarly, a short abrupt laugh followed by a quick departure could imply discomfort or a sudden realization. These examples showcase different emotions that can be linked to specific facial expressions or behaviors.
