Enjoying time on the lake is always fun and relaxing. Mrs. Selection has made wooden oars for over 15 years, but is looking to add another type of oar to sell along with the wooden one. She is not sure what properties are needed to make a good oar, or what other things are important, but she does know she wants it to look good so that she can sell as many as possible. Its your job to figure out what other material would be a good match for an oar, and prove it to Mrs. Selection. Maybe if the job is done well she'll take us all on a vacation to the lake.
