I was doing a listening practice and came across the material:
Professor: Recently there was an archeological excavation in Egypt, on the Nile River around where enters the Mediterranean Sea where they discovered an ancient glass factory.
Robert: I thought our textbook said the Egyptians imported their glass from other countries.
Professor: Well, until now that’s what the evidence seemed to suggest. I mean, we have some evidence that suggested that the Egyptians were making glass objects, but not glass.
Robert: Ok. Am……Am I missing something? They are making glass but they are not making glass?
Professor: I said they were making glass objects, right? You see, it was previously thought that they weren’t actually making the raw glass itself that they were importing unfinished glass from Mesopotamia.
The professor says "until now that’s what the evidence seemed to suggest.". Does the evidence include the recently found one? In other words, did the Egyptians make raw glass at that time?
