Final answer:
It's not possible to determine if Joel Weber is Shoshana's older brother without additional context, as these names do not correspond to well-known individuals in standard educational materials.
Step-by-step explanation:
Without additional context, it's impossible to determine if Joel Weber is Shoshana's older brother as this question pertains to specific individuals rather than a widely recognized fact or event. The names Joel Weber and Shoshana do not correspond to widely known historical figures or concepts covered in standard educational curricula, and personal relationships such as siblings are usually not a matter of public record unless the individuals are public figures.
If Joel Weber and Shoshana are characters from a literary work, tv show, or part of a hypothetical scenario in a learning module or textbook, more information would be necessary to accurately answer the question.
