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.

PROBLEM: Lanie Parish:  I pulled autopsy reports on the Phantom 's alleged victims . Total of seven ; _ four _ in L.A. , three in New York . All seven were killed with a knife .
Kevin Ryan: Any pattern besides the knife ?
Lanie Parish: No . The victims are all over the map . Four men , three women . Different ethnicities and ages . Each of the victims had something removed ; an ear , an eye , a finger .
Kevin Ryan: Why ? What 's the significance of that ?
Lanie Parish: There is none . And because of the randomness , no one was able to connect the murders . Until Phillip Harris , of course .
Javier Esposito: So Phillip was right . A serial killer 's been hunting in L.A. and New York for three years completely under the radar .

SOLUTION: REFERENCE victims

PROBLEM: Richard Castle:  Who 's Napolitano ?
Kevin Ryan: Oh , he worked with Raglan on a couple of drug busts . But he was at his daughter 's wedding the night Bob Armen was shot , so he 's not our third cop .
Richard Castle: Where is he now ?
Javier Esposito: He died of heart failure , back in _ 1993 _ . Why are you asking about Napolitano ?
Richard Castle: Uh ... he and Raglan are listed as the arresting officers on this report . But ... this has been altered .
Javier Esposito: What ?
Kevin Ryan: How can you tell ?
Richard Castle: Because I know typewriters . Older typewriters use cloth ribbon . If you look closely , you can see the striations in the typeface . Newer typewriters use film ribbon . Someone whited - out the assisting officer 's name on this report , photocopied it , and then typed in Napolitano 's name . It 's a cover - up , literally .
Javier Esposito: I 'll be damned .

SOLUTION: YEAR

PROBLEM: Lilith:  No , you do n't understand . Usually , we do n't get attached to the rats , but this _ one _ was so special . We even named him . Everyone in the lab called him Whitey .

Lilith: No , Carla , they were talking about Whitey the rat .
Carla: Okay , I 'll ask again . Are you sure they were n't talking to you ?

SOLUTION:
REFERENCE rats
