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.

Lanie Parish:  Kate , I talked Castle 's doctor into letting me look him over , and I came across a few ... strange things .
Kate Beckett: Strange how ?
Lanie Parish: No trace evidence on Castle 's clothes . But did find a key sewn into the lining of his pants .
Kate Beckett: What kind of a key ?
Lanie Parish: I 'm not sure , but it has " _ 38 _ " stamped on it . That mean anything to you ?
Kate Beckett: No .
Lanie Parish: Okay . Then there 's his blood work . I found antibodies to Dengue fever . That means Castle was exposed to the virus within the last two months .
Kate Beckett: Wait . Is n't Dengue fever tropical ?
Lanie Parish: Yeah ! It 's mostly found in Latin America , Africa , and Asia .
Kate Beckett: That does n't make any sense .
Lanie Parish: Neither does the bullet wound I found . Castle was grazed across the ribs .
Kate Beckett: Okay , that makes a little bit more sense . There were bullet holes on the boat .
Lanie Parish: But this wound was mainly healed . He was shot a few weeks ago .
Kate Beckett: A few weeks ago ? Are you sure ?
Lanie Parish: Maybe even longer . Kate , what the hell was Castle mixed up in ?
