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.

Now, solve this instance: Aang:  I do n't understand .
Aang: Why
Aang: did n't you free yourself ? Why did you surrender when Omashu was invaded ? What 's the matter with you , Bumi ?
King Bumi: Listen to me , Aang . There are options in fighting , called " jing . " It 's a choice of how you direct your energy .
Aang: I know .
Aang: here
Aang: 's positive jing when you 're attacking and negative jing when you 're retreating .
King Bumi: And neutral jing , when you do nothing .
Aang: There are * three * jings ?
King Bumi: Well , technically there are _ eighty _ five , but let 's just focus on the third . Neutral jing is the key to Earthbending . It involves listening and waiting for the right moment to strike .
Aang: That 's why you surrendered , is n't it ?
King Bumi: Yes , and that 's why I ca n't leave now .
Aang: I guess I need to find someone else to teach me Earthbending .
King Bumi: Your teacher will be someone who has mastered neutral jing . You need to find someone who waits and listens before striking .
