Example Input: Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging. <sep>How is it a win-win to buy durable goods?<sep>You will have more things at a lower cost
Example Output: No

Example Input: Littlefoot 's grandfather one night tells the children a story about `` The Lone Dinosaur '' , a legendary longneck who once protected the Great Valley from the most ferocious sharptooth ever to live . A fight ensued , which led to the Sharptooth 's death . However , the sharptooth left `` The Lone Dinosaur '' with a scar slashed across his right eye . Soon after the battle , a huge monolith that resembled a proud sauropod , having life-sized Sharptooth teeth arranged around his neck , came out of the ground during an earthquake . The dinosaurs called it `` Saurus Rock '' . The legend also states that if anyone damages the monolith , bad luck would descend upon the valley . A few days later when the kids are playing , Littlefoot accidentally falls off a cliff . Just before he hits the ground , a gruff Diplodocus rescues him . This longneck introduces himself only as `` Doc '' and gives no knowledge of his history . Littlefoot is intrigued by this newcomer , who is scarred across one eye and displays prior knowledge of the Great Valley 's topography . For the preceding reasons , Littlefoot assumes that Doc is the Lone Dinosaur . He tells his friends this , narrating an apparently extemporaneous legend to support his assumption . Inspired , Cera 's infant nieces , the twins Dinah and Dana , go to Saurus Rock without anyone noticing . Later when the friends are playing , they notice that Dinah and Dana are missing . Recalling their talk of the day before , they go to Saurus Rock to find them . <sep>Who was the enemy of the Dinosaur?<sep>Sharptooth
