Until recently, many plastic water bottles contained a chemical known as BPA, which has been shown to be a carcinogen. Now, most plastic bottles and containers no longer contain BPA and so are much safer to use than plastics produced just a few years ago.

Which one of the following is best supported by the information above?
  1. It is safer to drink tap water than to drink from a bottle containing BPA.
  2. BPA is unsafe at any levels.
  3. It was not until scientists discovered that BPA caused cancer that manufacturers looked into ways to make plastic bottles without BPA.
  4. Today there is no risk to drinking from a plastic bottle as compared to alternatives, such as aluminum.
  5. If you drink from a plastic water bottle today, it is likely, but not guaranteed, that the bottle does not contain BPA.
Explanation
Answer: E - The assumption that if you drink from a plastic water bottle today it is likely, but not guaranteed, that the bottle does not contain BPA is best supported by the information from the passage. All of the other responses could be true, but may not be.
