below each text by choosing A,B,C or D.Mark your answers on the ANSWER SHEET.(40 points)Text 1Nearly 2000 years ago,as the Romans began to pull out of Scotland,they left behind acurious treasure:10 tons of nails,nearly a million of the things.The nail hoard was discovered in1960 in a four-metre-deep pit covered by two metres of gravel.Why had the Romans buried a million nails?The likely explanation is that the withdrawalwas rushed,and they didnt want the local Caledonians getting their hands on 10 tons ofweapon-grade iron.The Romans buried the nails so deep that they would not be discovered foralmost two millennia.Later civilisations would value the skilled blacksmiths labour in a nail even more than theraw material.As Roma Agrawal explains in her new delightful book Nuts and Bolts,early17th-century Virginians would sometimes burn down their homes if they were planning to relocate.This was an attempt to recover the valuable nails,which could be reused after sifting the ashes.The idea that one might burn down an entire house just to reclaim the nails underlines how scarce,costly and valuable the simple-seeming technology was.The price of nails fell by 90%between the late 1700s and mid-1900s,as economist DanielSichel points out in a research paper.According to Sichel,although the falling price of nails wasdriven partly by cheaper iron and cheaper energy,most of the credit goes to nail manufactures whosimply found more efficient ways to turn steel into nails.Nails themselves have changed over the years,but Sichel studied them because they haventchanged much.Roman lamps and Roman chariots are very different from LED strips and sportscars,but Roman nails are still clearly nails.It would be absurd to try to track the changing price ofsports cars since 1695,but to ask the same question of nails makes perfect sense.I make no apology for being obsessed by a particular feature of these objects:their price.Iam an economist,after all.After writing two books about the history of inventions,one thing Ivelearnt is that while it is the enchantingly sophisticated technologies that get all the hype,its thecheap technologies that change the world.The Gutenberg printing press transformed civilisation not by changing the nature of writingbut by changing its cost-and it would have achieved little without a parallel collapse in the price ofsurfaces to write on,thanks to an often-ove。
