Which sentence is the claim?
Read each statement and match with the correct C-E-R method.
Plastic bottles should be completely banned.
Claim
Based on a study by USC, "every year billions of plastic bottles are landfilled, incinerated, or dumped in the ocean, where they leach pollutants into our water, air, soil, and food."
Evidence
This proves that plastic bottles should be completely banned because plastic bottles ruin our environment.
