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? Solve this instance: Wizard - Host:  It was a time of chaos . The unstoppable Cragmite empire wreaked havoc across the galaxy until a race of unlikely heroes fought back : the Lombaxes , who may be some sort of lemur - wombat .
Boomstick - Host: Well , whatever they are , they 're pretty good at kicking the shit out of Cragmites and ended up stopping the empire by banishing them to another dimension . Well , all except one and boy , would that come back to bite 'em in the ass !
Wizard - Host: Raised as one of their own , the last Cragmite betrayed his foster Lombaxes , raised an army of fish people , and , in some sense of cruel ironic justice , banished the entire Lombax race to their own dimension as well . And , just as ironically , missed one who would prove to be his greatest adversary .
Boomstick - Host: This lone Lombax 's name was Ratchet , and he spent most of his days stranded on a random planet , dicking around with mechanical stuff , and dreaming of one day exploring the galaxy . So , this alien ... kitty cat ... thing scrounged up all the scraps he can find , used his natural gift with machines , and built a space ship so incredible , it would finally take him off this boring planet once and for ...
Boomstick - Host: ...
Boomstick - Host: all .
Wizard - Host: Without an onboard robot ignition system , this hunk of junk would never fly .
Boomstick - Host: And with Ratchet 's luck , it 's not like _ one _ was just gon na drop out of the sky or something .
Boomstick - Host: Well
Boomstick - Host: , I 'll be damned .
Wizard - Host: This was the sentry bot serial number XJ-0461 .
Boomstick - Host: But that 's hard to say in conversation , and he makes a clanky sound when he falls over , so ...
Clank: Maybe I 'll just call ya ... Clank .
Wizard - Host: Clank had just been assembled maybe half an hour earlier , and was already running for his life .
Boomstick - Host: Yeah , see , he came from a robot killing machine making factory , but when the factory malfunctioned and made this little guy , it decided to scrap him for parts . So , naturally , he got the hell out of there , ended up with Ratchet , and together they became the greatest hero duo in the galaxy .
