Answer:
1. sound waves
2. eardrum vibrates
3. the bones in the middle ear amplify
4. the hair cells move up and down
I'm pretty sure the answer is D because it seems like the most logical statement that could be made by an explorer.
Art Noveau is portrayed by many women with long hair and floral backgrounds so maybe you could advertise a certain beauty product, like maybe a fragrance with the aroma of spring flowers. Or maybe a new fancy beverage like wine or champagne or something. Hope this helps!!
