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.

Hal Jordan:  As a Green Lantern , I face some of the nastiest villains in the galaxy . Then I met Star Sapphire . She was different . Easy on the eyes . And we actually had a lot in common . She was a humble Earthling who encountered some otherworldly beings , the Zamorans . They chose her to be a host body for their queen . I ca n't say I blame them . They even gave her a ring . But it came with a hitch : once that ring slid onto her finger , she was a changed woman . She became a being of pure evil , bent on the conquest of Earth . I never had any problems with ladies before , but like I said , this _ one _ is different .
