First digit was 0.The extinction of Moa birds was due to humans hunting them for proteins.. so Humans is the answer I think
Regarding the "what does speaker think of Paul's experiments".. I think the answer is something like "hope/almost it is true". I don't think it is "certainly true" as she starts in a very +ve note about the experiments, but ends it something like.. "lets get the results to close the matter once and for all". So, she sounds very +ve about it but she want Paul to confirm it.
What was the 1st digit of phone number in section 1? Was it '0' or '1'???
Also..the question was what the lady thinks..not paul...and lady was certain..anyways not sure about ans..
