Sam is writing a research paper on the benefits of healthy eating habits. He drew a chart to help him brainstorm his thoughts which three items on the chart would be best for him

You did not attach the chart that the question is referring to, but I can help you by stating that the items on the chart that would best provide information about Sam's work would be the items that showed the association of some foods with the increase in benefits in the body, or the association of some foods with the reduction of malefic factors for the body.

Explanation:

Sam needs to use the graph to support his research and the arguments he wants to make about the importance of food for human health. To do this he must carefully analyze the items on the graph and observe the relationship that each item establishes with the other.

The items that will best help Sam's research are those that associate a food with an increase in beneficial factors for the body. An example of this would be the association of lentils and peas with the increase in the body's iron content, which decreases the chances of anemia in an individual. It could also use the association of food with the reduction of malefic factors in the body. As an example of this, he could observe the association of fibrous foods with the reduction of digestive problems in an individual.

the correct answer is:   [c]:

                    →     " leave it out. "  

hope this is to you!

        best wishes!
