Final answer:
The provided stages do not correspond with Super's theory of occupational goals, and thus it's not possible to determine which stage Shelby is in without the correct terminology from Super's model.
Step-by-step explanation:
According to Super's theory of occupational goals, there are several stages of career development. However, the stages provided in the question do not match the terminology used in Super's career development model. Instead, they appear to reference Rostow's stages of economic growth or stages relating to family life cycles, product development, and societal movements. Super's theory describes stages such as Growth, Exploration, Establishment, Maintenance, and Disengagement. Therefore, it is not possible to accurately determine which stage 'Shelby' would be in without additional context or the correct stages from Super's theory. To provide an accurate response, we would need the correct stages according to Super's theory of career development.
