In this task, you will use your knowledge about language (and common sense) to determine what element the marked number refers to. 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. If none of them seems right to you, there's also an option for other. If your answer is "REFERENCE", also write the reference entity, otherwise write the implicit option name. Options to choose from are:
REFERENCE: Some object which is being mentioned in the text before or after the target number. The reference answer has a higher priority than any other. If both Reference and another answer are possible, prioritize the Reference.
YEAR: Describing a calendric year
AGE: Describing someone's age
CURRENCY: Reference to some monetary value e.g dollar, euro etc.
PEOPLE: Describing a single/plural persons
TIME: Describing a time of the day. Usually you can add the word o'clock after those numbers.

Example Input: 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 .
Example Output: YEAR

Example Input: Connie Rubirosa:  I told you not to get your hopes up .
Ted Sanderson: What do we do now ? We fight it . We go back to trial , right ?
Connie Rubirosa: Or we take the D.A. 's plea offer .
Ted Sanderson: Eight more years in prison ?
Connie Rubirosa: Counting the _ nine _ you 've already served , seventeen years is n't bad for two murders .
Ted Sanderson: Two murders ?
Connie Rubirosa: I have a theory . Your wife had an affair , but not with Dresner . With somebody else . You thought she might leave you , you got angry , so you called your old buddy Frank .
Ted Sanderson: What ? What are you talking about ?
Connie Rubirosa: Your old diving buddy , Frank . Frank you met in a diving class . He killed your wife for you , but in one of life 's little ironies , you were convicted on faulty evidence . And once that conviction was overturned , you got in touch with Frank .
Ted Sanderson: You 're wrong .
Connie Rubirosa: You found out he was about to get tested for cystic fibrosis , a genetic test that might bring him to the attention of the police who are still looking for an unknown murder suspect with a special disease .
Ted Sanderson: Ms. Rubirosa , it 's not true .
Connie Rubirosa: If Frank got caught , you would go back to prison , so you killed him . Like I said , it 's a theory . One that will remain between you and me , protected by the attorney / client privilege .
Ted Sanderson: But you believe it ? That 's why you want me to take a deal and go back to jail ?
Connie Rubirosa: I gave you my opinion . It 's a good deal .
Ted Sanderson: And if I do n't take it ?
Connie Rubirosa: Then we will go back to trial .
Ted Sanderson: And you tank the case . You 're gon na sell me out 'cause you think that ... I know how you people work .
Connie Rubirosa: You do n't know anything about the way I work . I am your lawyer , now same as then , and I will defend you to the fullest extent of the law . I will argue your case to the jury without reservation . That is what I 'm sworn to do . Now , you can take this plea or you can take your chances with the jury . You know how they can go . It 's up to you .
