Passage 2
Paper money is used every day but people do not often think of money as just paper.This is?because people agree that it has value,and paper money is supported by the government.
People have used paper money for only a few hundred years,but what did people do before?printed money was invented?In Medieval England,a stick was the official representation of money.The common system that was used involved counting debt on a piece of wood called a"tally stick".The tally stick was marked with a knife.Each mark,or tally,indicated an amount of money.The?tally stick acted as a contract.
No one really knows who invented the tally stick,but King Henry I of England is credited as?the first to use the stick in a widespread fashion.In England,the tally stick was used from?1100-1826.Marks were made on a tally stick to represent the amount of service or goods that were?exchanged.The tally stick was cut in half lengthwise into two parts,and one stick was longer than?the other.The person giving services or goods received the longer end of the stick,called the"stock",and the person paying for the service or goods received the shorter end.Once the stick was?cut,it could not be altered.When put together,the two halves fit perfectly together.
Medieval England was not the only country to use the tally stick system.In 1960,Belgian?scientist Jean de Heinzelin de Braucourt discovered an extremely old tally stick made of baboon?bone in Africa.At first,he determined the stick to be between about 8,000 to 10,000 years old.This?surprised many people because it proved that the tally stick system had been in use for much longer?than everyone had previously thought.Further research has shown that this stick is actually much?older:now,scientists believe it is 20,000 years old.
The tally stick system may no longer be in use today,but its influence is still apparent.People?still make contracts and people still borrow and lend money.People still trust that"things"--whether they are sticks,paper,or coins--have value.The next time paper money is used,just?remember:it is only paper!
Which of the following statements is true?

For hundreds of millions of years,turtles have struggled out of the sea to lay their eggs on sandy?beaches,long before there were nature documentaries to celebrate them,or GPS satellites and?marine biologists to track them,or volunteers to hand-carry the hatchlings down to the water′s edge?lest they become disoriented by headlights and crawl towards a motel parking lot instead．A?formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic?coastlines．With all that attention paid to them,you′d think these creatures would at least have the?gratitude not to go extinct．
But Nature is indifferent to human notions of fairness,and a report by the Fish and Wildlife?Service showed a worrisome drop in the populations of several species of North Atlantic turtles,notably loggerheads,which can grow to as much as 400 pounds．The South Florida nesting?population,the largest,has declined by 50%in the last decade,according to Elizabeth Griffin,a?marine biologist with the environmental group Oceana．The figures prompted Oceana to petition the?government to upgrade the level of protection for the North Atlantic loggerheads from"threatened"to"endangered"--meaning they are in danger of disappearing without additional help．
Which raises the obvious question:what else do these turtles want from us,anyway?．It turns?out,according to Griffin,that while we have done a good job of protecting the turtles for the weeks?they spend on land(as egg-laying females,as eggs and as hatchlings),we have neglected the years?they spend in the ocean．"The threat is from commercial fishing,"says Griffin．Trawlers(which drag?large nets through the water and along the ocean floor)and longline fishers(which can deploy?thousands of hooks on lines that can stretch for miles)take a heavy toll on turtles．
Of course,like every other environmental issue today,this is playing out against the?background of global warming and human interference with natural ecosystems．The narrow strips?of beach on which the turtles lay their eggs are being squeezed on one side by development and on?the other by the threat of rising sea levels as the oceans warm．Ultimately we must get a handle on?those issues as well,or a creature that outlived the dinosaurs will meet its end at the hands of?humans,leaving our descendants to wonder how creature so ugly could have won so much affection．
