In this task, you're given four sentences of a story written in natural language, and one last sentence (Sentence5). Your job is to classify whether the last sentence completes the rest of the story coherently or not by providing 'Yes' or 'No'.
One example: Sentence1: Rick grew up in a troubled household. Sentence2: He never found good support in family, and turned to gangs. Sentence3: It wasn't long before Rick got shot in a robbery. Sentence4: The incident caused him to turn a new leaf. 
 Sentence5: He is happy now.
Solution is here: Yes
Explanation: As mentioned in fourth sentence, the incident turned a new leaf to Rick's life; so, he must be happy now.

Now, solve this: Sentence1: The Smith's could not find their cat. Sentence2: They were afraid she had gotten outside and gotten lost. Sentence3: Everyone was sad when they sat down in front of the Christmas tree. Sentence4: Then they noticed her looking down at them from the top branches. 
 Sentence5: The Smiths all cheered, and rushed to hug their cat.
Solution:
