答案：they are complex
原文定位：I guess it would be pretty easy to fake one of those paintings;No way, Emily. I know a lot of people think that even a child could paint one. To the untrained eye, they might look simple, but they're incredibly intricate works of art
同义替换：「complex」↔「incredibly intricate」
答案：it lacked documentation
原文定位：Why;Well, one critic said that compared to other Pollocks, the white and yellow lines on the painting were too straight;Come on, Josh. That doesn't seem that convincing;No, you're right. It is a bit weak. But the strongest argument was that there were no records of previous owners. For the painting to be authentic, you really should be able to trace the painting all the way back to the artist's studio
同义替换：「because」↔「the strongest argument was that」，「it lacked documentation」↔「there were no records of previous owners」
答案：the type of paint used
原文定位：Did they consult with anyone else;Mm. The International Foundation for Art Research got involved;And what was their verdict;Well, they saw a definite similarity in the painting techniques used... And they noted the dirt and paint marks on the back, which all of Pollock's paintings have... But the foundation were worried about the acrylic paint that was used on the painting. It's quite common now, but it was very unusual back in Pollock's day
同义替换：「reject」↔「worried about」
答案：Experts from the science and art worlds should work together.
原文定位：Art historians have always judged paintings, but things are changing now. If we have modern scientific techniques like fingerprint analysis, why not use them;Mm, that's true. Well, maybe we need a combination;I think you're right
同义替换：「Experts」↔「art historians」，「should work together」↔「need a combination」，「art evaluation」↔「authenticity」
答案：a laser scanner
原文定位：Right. So Seracini had a theory that the painting was still there, and he set out to prove it. He used a lot of different technology, like radar and thermographic cameras. But initially, he scanned every inch of the hall with a laser in order to make a really accurate three-D model of the building's design
同义替换：「to help make a model of the building」↔「in order to make a really accurate three-D model of the building's design」
答案：a thermgraphic camera
原文定位：Exactly. Then, to find out what the hall looked like in Leonardo's time, he took pictures of it with a thermographic camera;Couldn't he have used ultrasound to do that;Not really. Different types of building materials produce different amounts of radiation, and you can really see those differences in a thermal image
同义替换：「to reveal different materials in the wall」↔「Different types of building materials produce different amounts of radiation, and you can really see those differences in a thermal image」
答案：glass
原文定位：Yes. Seracini worked out what the building looked like when it was first built and what renovations took place after that. He found that two large glass windows on the east wall had been removed and filled in by the time Da Vinci started work on his painting, leaving a space big enough for it
同义替换：「in a space that used to hold」↔「leaving a space big enough for it」
答案：a radar machine
原文定位：Did he use the thermographic camera again;No. This time, he used another kind of technology, radar;And what did that show;It showed there were, in fact, two walls there, an older one and a newer one built in front of it
同义替换：「discovered a second wall behind it」↔「It showed there were, in fact, two walls there, an older one and a newer one built in front of it」
答案：stone
原文定位：So does Seracini believe that Da Vinci's painting is on the concealed wall;Yes, on a stone wall concealed by the newer brick wall
同义替换：「hypothesised」↔「believe」
答案：gamma-ray technology
原文定位：So what's the next stage in the investigation;Well, he isn't allowed to remove any plaster or bricks, so he's now experimenting with a gamma ray camera to try and verify his theory
同义替换：「prove」↔「verify」，「using」↔「experimenting with」
