Answer:
According to many people, organic food is healthier
because it does not contain the residue of pesticides.
However, numerous food scientists say that studies
have not proven that organic food is healthier. Furthermore
scientific studies have never conclusively linked pesticides
consumed on fruits and vegetables with cancer in humans.
Explanation:
First let us analyze two parts of this paragraph. First part praises organic food stating its positive health impacts and lack of pesticides. Second part does the opposite; it quotes scientific studies stating that there are no proves for claiming that organic food is healthier or that the pesticides cause cancer. Since these two parts are stating opposite things, we need to use opposing linkage such as <em>however</em>. The second part consists of two sentences which both gives us counterclaims for the first part. Since the second claim explains the first more clearly, giving us more details about it, here we need to use <em>furthermore</em>.
