Final answer:
The question asks what Sandra attributes her extreme anxiety to, with options including experiences in her workplace, childhood, or community. However, without explicit details linking to these options, 'none of the above' might be selected.
Step-by-step explanation:
Sandra suffers from extreme anxiety whenever she leaves her home. The question asks what Sandra attributes her fear and anxiety to. Based on the context provided, which mentions experiences at her workplace, suffering during her childhood, and what she witnessed in her community, her anxiety can be linked to the trauma and challenging experiences in her past. However, without a specific time frame or situational context, it is impossible to determine definitively which of these experiences is the source of her anxiety. Therefore, none of the above might be chosen as an answer if the details in the question do not exactly match the options given.
