Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.

Context: Once upon a time , when I was raising my " first family , " I frequently encountered the attitude of the Women 's Liberation Front that would have me believe that a woman who chose to stay home and raise her children was simply too stupid to do anything else with her life . The " mommy wars " were pretty vicious back then ! So , after almost twenty years of being a stay - at - home mom , I returned to college and earned three degrees ( so much for being too stupid ! ) and then worked away from home as a college instructor for several years .
Why did I return to college ?

Context: So since he was talking three miles a second , he did n't actually realize , that his next beer bottle was momentarily refilled .

Ick ! But his face was priceless . Since the day had begun so good , something had to happen to make it worse .

How was his face priceless .?
