Final answer:
Without the details of Scenario 3.4, it's impossible to specify which legally protected ground is violated, but it would be one of the grounds protected by the EEOC, such as pregnancy, religion, or age.
Step-by-step explanation:
The question refers to which legally protected ground appears to be violated in the given scenario. However, without the specifics of Scenario 3.4 stated in the original question, we can only reference the information provided which suggests that the violation pertains to either pregnancy, religion, or age. According to Figure 13.11 and the information about the U.S. Equal Employment Opportunity Commission (EEOC), these criteria are indeed protected, and employment decisions cannot legally be made based on them.
It's important to note that the Civil Rights Act of 1964 and subsequent laws enforced by the EEOC expressly prohibit discrimination based on race, color, religion, sex (including pregnancy), or national origin, among others. Given this context, without the specifics of Scenario 3.4, pinpointing the exact ground of discrimination is challenging, but one of these identified bases for protection would be the violated ground in the hypothetical or provided scenario.
