Jena is doing research for a presentation about pesticides in the fruits and vegetables people eat. Which source provides the most reliable information for research? a university site showing the results of a study on which foods absorb chemicals a personal blog that talks about the superiority of organic fruits and vegetables a wiki that explains how to use pesticides sparingly on vegetable gardens a website that sells products designed for pest control in gardens

The answer is A: a university site showing the results of a study on which foods absorb chemicals.

The source of option A provides the most reliable information for Jena's research because the university site is not only presenting an opinion or suggestion about the subject, but it is showing the results of a study about the relation of the chemicals, the foods and absorbency conditions etc. A blog, a wiki and a website will probably have to use the same information in order to write their articles.
