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.

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.

question:
David Rossi:  Victim one gets dropped here .
Derek Morgan: While number two comes around the corner to see what 's happening , and ... the unsub attacks him here .
Emily Prentiss: The female victims were probably here when the first attack occurred .
Derek Morgan: Which means somebody would have to control them pretty quickly .
Emily Prentiss: How many unsubs are you thinking ?
David Rossi: At least one to move the body inside , another one to take out man number two , and one more to subdue the others .
Emily Prentiss: Well , vandalism breeds a pack mentality .
Derek Morgan: If it is the same unsubs , then yeah , we 're looking at a group of three , maybe _ four _ .
David Rossi: These are n't kids . They 're too efficient . There 's control and precision . Juveniles are sloppy .
Emily Prentiss: He 's right . There is nothing tentative about these kills . There 's no experimentation . These guys know what they 're doing .
Derek Morgan: I do n't know ...
David Rossi: What are you thinking ?
Derek Morgan: I can understand vandalism escalating into violence , but that 's usually gradual . An assault , a single murder maybe , but come on , this ? This feel fully evolved .
