Teacher: 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.

Teacher: Now, understand the problem? If you are still confused, see the following example:
Jess Mastriani: No, I don't want another crooler, thank you very much.
 FBI Agent Nicole Scott: But it's good for you. It's got... honeyglaze. Please die for this crooler, Jess.
 Jess Mastriani: I've had _ two _ already. Who eats three croolers in a night? 
FBI Agent Nicole Scott: Take a look. [Nicole takes a huge bite] Mmmmm, Mmmmm, Mmmmm!
Solution: REFERENCE crooler

Now, solve this instance: Emily Prentiss:  No , it 's more personal than that . It 's their story .
Derek Morgan: What ?
Emily Prentiss: All of the details are a part of their story . Their timeline suggests they were both destructive before they met .
Erin Strauss: So , we 're talking about ex - military turning on their country .
Emily Prentiss: It 's rare , but soldiers become disenfranchised no matter what the nationality . And if he met someone like - minded at that time , there 'd be no stopping them .
Aaron Hotchner: So , you 're thinking they met during the civil unrest in Chad in ' 8 .
Dr. Spencer Reid: Yeah , and one or both of them are pilots .
Emily Prentiss: So , if Garcia concentrates on that region , specifically weapons running in and out of Libya , there 's a good chance we 'll find their paths crossed .
Penelope Garcia: Okay , multiple entries into Libya from a private pilot named Matthew Downs in ' _ 8 _ , but I do n't have her name .
Emily Prentiss: Well , because she had aliases . It 's the only way to stay a ghost . Here 's the thing . They are a couple . Regardless of what we believe of them , they will celebrate themselves and their connection . Is there anything that happened on this date in Chad ?
Penelope Garcia: Oh , you are good , Emily Prentiss . But this news is not . Yes , there were multiple explosions on this date in ' 8 .
Aaron Hotchner: Where were the most casualties ?
Penelope Garcia: At a church . No , no , a train .
Derek Morgan: Semtex and C-4 ?
