What is the first name of the person who only has a GED?  Answer the above question based on the context below:  Maya Vargas is the assistant manager of the Value Shop store she has worked at for the past 15 years.  During that time she dramatically improved sales, customer relations, and general store culture through her intuitive and innovative methods.  She awaits a store visit by an executive of her company, Mr. Weiskopf, anxiously hoping to be promoted to manager.  Her boyfriend Trey, co-workers, and several regular customers all assure Maya she's guaranteed the promotion, but instead she's passed up in favor of Arthur, a non-local company employee with an MBA from Duke.  Mr. Weiskopf explains that while he values Maya's dedication and success, she only has a GED and no college degree, which makes her ineligible for the promotion by company policy.  Maya is bitterly disappointed but reluctantly agrees to stay on as Arthur's second-in-command at the store.
