Teacher: 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 _. Your answer should be chosen from the given text, and should not contain other words.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Jess Mastriani: No, I don't want another crooler, thank you very much.
FBI Agent Nicole Scott: But it's good for you. It's got... honeyglaze. Please die for this crooler, Jess.
Jess Mastriani: I've had _ two _ already. Who eats three croolers in a night?
FBI Agent Nicole Scott: Take a look. [Nicole takes a huge bite] Mmmmm, Mmmmm, Mmmmm!
Solution: crooler
Reason: In this example, the number two refers to something that the word: crooler.

Now, solve this instance: Diane Chambers: She was the only _ one _ in my life who was always there . When everybody else was mad at me , she always liked me . When I 'd hide when my parents argued , she 'd come with me , and whenever I was sick , she never left my bed until I was well again . And then when I was twelve years old , my parents separated . It was maybe the worst night of my life . Believe it or not , I actually thought about throwing myself in the lake . But then I looked down at this cat in my lap and I thought , Who would take care of Elizabeth ? She saved my life that night . And I know it 's crazy and it 's irrational , but ... Oh Sam , I ca n't help thinking that last night when her time came she must 've wondered where I was .
