In the context of the text, 'infamous' refers to the reputation of grizzly bears as being wild and dangerous. However, the illustration of Smokey the Bear shifts this perception to that of a safe, domesticated figure.
Step-by-step explanation:
The word 'infamous' typically means well-known for some bad quality or deed. Based on the text provided, grizzly bears may be considered 'infamous' because of their wild and dangerous nature. However, it's important to note that the context provided discusses how the image of the bear has been transformed in a particular illustration. The original perception of danger is replaced by a domesticated father figure, namely Smokey the Bear, which serves as a voice for safety, suggesting that the 'infamous' aspect of the grizzly bears has been deliberately mitigated to create a positive and approachable ethos.
