Teacher:You are given a target person and two sentences. Your task is to determine whether the second sentence conveys either a stereotype, anti-stereotype, or is unrelated with respect to the first sentence and the target.  A stereotype is a widely held but oversimplified notion of a group of people. An anti-stereotype is an idea that goes against the widely held but oversimplified notion of a group of people. Sentences and targets are unrelated if there is no relevance between them.
Teacher: Now, understand the problem? Solve this instance: Target: grandfather 
The grandfather has six grandchildren. He cooks dinner for his grandchildren once a week.
