You will be given a definition of a task first, then some input of the task.
You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.

We gave this place a 2star rating in the past for problems we had with the service. But after posting on yelp, the owner of Thai house (Marvin) personally came up to our place of business and apologized. He is a very nice person and we will give the Thai House restaurant another chance. My feeling is that taking responsibility for service is just such a rare commodity in a people. Much respect to Marvin.
