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.
OTHER: Some other option, which isn't listed here.
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
Reason: In this example, the number two refers to something that appears in this text. In this example, it refers to the word: crooler.

Kate Beckett: No , I will tell you what makes sense , Dr. Weiss . Either you 're part of a cover - up or you 're a murderer or both .
Dr. Ari Weiss: What ? Wh ... why would I kill anyone ? I have a family .
Kate Beckett: Well , then did you take them into consideration when you colluded in moving a body from a murder scene ?
Dr. Ari Weiss: That was a _ one _ in a million circumstance , and everyone ended up getting what they needed .
Kate Beckett: Then why is it at every step of this investigation , you have gotten in my way ? Hamilton ends up dead and in your custody ; the DA 's about to turn over the body to me , and you negotiate to keep the head ; I get a warrant for the head , and suddenly it ends up missing .
