But now radiocarbon testing has established the remains - discovered in a stone box grave in Edinburgh by 19th century workmen - are hundreds of years older than anyone realised.It has become clear the skull belonged to a Bronze Age man who lived in the area which almost 4000 years later became Juniper Green.Best Friends Michael Wu, 58, software consultant and Kevin Wu, 20, Internet entertainer, Sugar Land, Texas. and Mallory Ervin, 24, Miss Kentucky 2009, Lexington.RC: Father/Son Chad Waltrip, 26, operations manager and Stephanie Smith, 23, hair stylist, Ft.

Nonetheless, dinosaur bone apatite had been successfully RC dated in the late 1980's/early 1990's and significant amounts of C-14 were detected and reported.The data was challenged by Thomas Stafford as poor science due to assumed contamination from modern C-14 with younger surficial calcium carbonate.I think I was fooled by (E) because it was directly quotable from the passage whereas (B) was an unstated inference based on what we know about radiocarbon dating. I still don't understand why (B) is right and (E) is wrong.
When in fact, the researchers simply said that those factors needed to be taken into account.E goes too far by saying that lichenometry's usefulness is limited.If you look back at lines 54-58, the passage says that conditions affecting normal lichen growth must be factored in. I agree with the above poster's reasoning for why (E) is incorrect.It was handed over to archaeologists at the time and ever since has been kept in a collection which became part of the National Museum of Scotland.However, no-one realised the significance of the find, until now, with little known about the precise age of the skull.
