Definition: 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.
Input: Officer Peter J. Malloy:  From now on , she 'll have to open her own doors . Carry her own troubles . And her childrens ' . Alone . From now on , it 's just the three of them , instead of just the _ four _ . And if there must be a final postscript to all of this , then let it here be noted : the coffin will soon be buried . He will be forgotten except by a very few . Out of sight , out of mind . And strangely enough , in view of current custom , no one will raise a placard to denounce his senseless murder . No one will raise indignant cries of protest at the shedding of his blood . No one will march in anger because of his death .
