Definition: 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.
Input: Context: It 's so much nicer than having a busy old street for a view . Here are the dresses that I found at the antique sale this weekend . When I first got to the sale and wandered over to the vintage clothing room I got disappointed that there was nothing at all that interested me . But then I found these three dresses hanging on a wall in another room , and I knew I had to get them . The two on the left are from the ' 50s and the one on the right is from the ' 40s .

What may be the reason for their trip to the antique sales ?
