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.

Let me give you an 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!
The answer to this example can be: REFERENCE crooler
Here is why: In this example, the number two refers to something that appears in this text. In this example, it refers to the word: crooler.

OK. solve this:
Captain Kathryn Janeway:  You 're not suggesting we wait until this ... Chaotica defeats the aliens ?
Tom Paris: No , no . I 'm suggesting , that we help the aliens to defeat Chaotica . They think he 's leading some kind of hostile invasion force , once that threat is gone it 's a good bet they will leave and close up their portals .
Chakotay: How do you propose to defeat Chaotica ?
Tom Paris: Well , he 's been attacking the aliens with his Death Ray ...
Tuvok: It 's a shame we do n't have _ one _ .
Tom Paris: No , forget about what it 's called Tuvok ! In the world of Captain Proton it 's the most powerful weapon that there is , and because it 's photonic it 's lethal to these aliens . Now , in chapter 18 Captain Proton disables this weapon Just before Chaotica can use it to destroy Earth .
Captain Kathryn Janeway: And you think that Proton - namely you , of course - could still do that ?
Tom Paris: Well , we 'd have to knock out the Lightning Shield first ...
Seven of Nine: A force - field .
Tom Paris: Yep , now you 're catching on . The Destruct - o Beam on my Rocket Ship can can disable the Death Ray but only if someone gets inside the Fortress of Doom and can shut down the Lightning Shield .
