The guys built this sculpture / bench area while I was skim boarding further out with Quill . Quill ( blonde ) and Dillion ( brown hair ) are the ones you see skimboarding . Clark and Eric are sitting on benches they built . Mark 's the unaccounted for figure , he was doing poi .

Question: What is a likely reason that Clark and Eric built a sculpture and benches ?
Answer: None of the above choices .They are in a bench building competition and are vying to get the gold medal for the best benchThey are being judged on who can build the best bench possible and will win a beach passThey wanted something fun to do , and incidentally ended up with somewhere to sit as well
