TASK 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

PROBLEM: FBI Special Agent Seeley Booth:  Here we are , all of us , basically alone , separate creatures , just circling each other , all searching for that slightest hint of a real connection .

Why ? Because every once in a while ... every once in a while , two people meet and there 's that spark , and yes , Bones , he 's handsome and she 's beautiful and maybe that 's all they see at first , but making love ... making love ... that 's when two people become _ one _ .
Dr. Temperance Brennan: It is scientifically impossible for two objects to occupy the same space .
