You will be given a definition of a task first, then some input of the task.
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.

Zoe:  How did you pilot the rocket , Doctor ?
Dr. Who: I do n't think we 've met have we ?
Dr. Gemma Corwyn: Zoe ... Doctor ... John Smith , is n't it ?
Jamie: John ... John ...
Dr. Who: John ... John ...
Zoe: I 'm an astrophysicist . Pure - mathematics major .
Dr. Gemma Corwyn: With honors .
Dr. Who: Oh , I am impressed .
Dr. Gemma Corwyn: We use Zoe as our second opinion .
Zoe: You did n't answer my question .
Dr. Who: What question ?
Jamie: You know , I surprised you did n't know the answer . Now , do n't tell me there is something you ca n't work out !
Zoe: How did you pilot the rocket ship ? You see , I 've calculated its original course . It was a surface and supply station for Number Five Station , overdue and presumed lost nine weeks ago . Well the rocket could n't have drifted eighty seven million miles off course .
Dr. Who: So what 's your theory ?
Zoe: Well , there is a record of the last contract with the Silver Carrier rocket . It had seven million miles to touchdown , and enough fuel for _ twenty _ million . Well , it could n't have drifted here off course in the time involved . It must have been driven and piloted .
Jamie: Och , you are a right wee space - detective !
Zoe: There 's only one solution . That rocket was re - fuelled in space . - Provided for at least with another twelve fuel rods .
Dr. Who: Well , it is an interesting theory ...
Zoe: Oh , it is n't a theory . You ca n't disprove the facts . It 's pure logic .
Dr. Who: Logic , my dear Zoe , merely enables one to be wrong with authority . Supposing there was a faulty automatic pilot ?
Zoe: To drive a rocket eighty seven million miles on fuel for twenty million ?
Dr. Who: Well , it 's a possibility .
Zoe: That rocket was driven here somehow . I know it was .
Output:
REFERENCE miles
