The numbers are marked with two underlines around them, like: _ number _. There are several possible answers, you'll need to choose the proper one. Carefully read the given text, pay special attention to the marked number, think about what (unwritten) information the marked number holds inside, choose the most adequate word(s) from the optional answers.

question:
Derek Morgan:  What 'd you find , Reid ?
Dr. Spencer Reid: I went back ten years , matching reports of missing children with Daniel and Tyler 's victimology , and in my estimation , this UnSub may have taken 12 victims .
David Rossi: How can you attribute all of those to the same offender ?
Dr. Spencer Reid: The dates and locations of the abductions create an unmistakable pattern .
Emily Prentiss: Now , if he 's been abducting children for ten years , why were n't we called in before now ?
Dr. Spencer Reid: The thing is , he walks the entire trail , end to end , and each way takes approximately six months . His sixth victim was taken from Dawsonville , Georgia , in _ 2006 _ . Then he walked all the way to Manchester , Vermont , and he took a seventh victim in 2007 . He was n't down south again until 2009 , when James Clutter 's parents woke up from a night of camping , he was gone . They just assumed he wandered off .
Aaron 'Hotch' Hotchner: We did n't get called in because nobody knew he existed . The crimes are years apart and across state lines .
Dr. Spencer Reid: The interesting thing is , ten years ago he was a more aggressive hunter , likely on the move hunting and killing all 365 days a year , but two years ago he stopped travelling so far .
Emily Prentiss: He 's slowing down .
Dr. Spencer Reid: I think something 's affected his mobility , or old age , or an injury from years of living on the trail . But the odd thing is , for the past two winters , he 's returned to this 30 mile radius . He takes a victim with him in the fall to stay with him until spring somewhere within that area .
David Rossi: These are harsh winters . He needs to find shelter .
Derek Morgan: And it would have to be heavily camouflaged . Even the most experienced hikers haven't seen it .
