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: Professor Richard Lazarus:  I find that nothing 's ever exactly like you expect . There 's always something to surprise you . Between the idea and the reality , between the motion and the act ...
The Doctor: Falls the shadow .
Professor Richard Lazarus: So the mysterious Doctor knows his T.S. Eliot . I 'm impressed
The Doctor: Would n't have thought you 'd have time for poetry , Lazarus , what with you being so busy defying the laws of nature and everything .
Professor Richard Lazarus: You 're right , Doctor . One lifetime 's been too short for me to do everything I 'd like . How much more I 'll get done in two , or three , or four .
The Doctor: It does n't work like that . Some people live more in twenty years than others do in _ eighty _ . It 's not the time that matters , it 's the person .
Professor Richard Lazarus: But if it 's the right person , what a gift that would be .
The Doctor: Or what a curse . Look at what you 've done to yourself .
Professor Richard Lazarus: Who are you to judge me ?
