When searching a business on Google, how can you change what snippets of a review site are shown? Especially regarding Yelp

Have a question about what results Google pulls when searching for a small business. A client I represent has many 4 and 5 star reviews on Yelp. However, when you Google this store’s name, Yelp returns second and the snippet beneath that is terrible review by a lunatic customer. So the second result on Google Search is Yelp, with a specific highlighting of the bad review. 1. Why does Google show THAT specific review when pulling up the Yelp result, and not one of the many 4 or 5 star ones (which far outnumber this one review)? 2. Is this a Google issue or Yelp issue? Does Yelp select what gets brought up on a Google search? 3. How can this be changed? Thanks!
