In this task, you're given four sentences of a story written in natural language. The given story is not complete and your job is to complete the story by selecting one of the end sentence choices from (A) and (B), such that the story does not sound complete and coherent, i.e., select an incorrect end sentence.
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. 
 (A) He is happy now. (B) He joined a gang.
Solution is here: B
Explanation: As mentioned in fourth sentence, the incident turned a new leaf to Rick's life; so, he must be happy now. Also, he was previously in gang, so, this incident cannot make him to join a gang. So, B is incorrect.

Now, solve this: Sentence1: Bob was going to take his daughter to see Grandma. Sentence2: The two drove to Grandma's house a few miles down the street. Sentence3: Grandma welcomed them with open arms. Sentence4: The 3 of them had a big dinner at night. 
 (A) Bob's daughter thanked Grandma for the delicious meal. (B) Bob angrily drove home after the meal.
Solution:
B
