DIRECTION: Read the paragraph and find the correct assumption that answer them below: Studies last year concluded coffee drinking had little, if any, effect on the risk of pancreatic or kidney cancer.

Which of the following statements, if true, would weaken the conclusion drawn above?Choices:- The study is done in cold countries only, countries in arid and semi-arid regions are not considered under this study.

The study did not consider the milk intake.
