Answer:
The area in which the author backs up her claim with an evidence was when she included a research study printed in the 'Journal of Social and Personal Relationships.'
Explanation:
'Turning Off, Dining In' is an article which states the importance of dining out with family by keeping all the electronic devices and other distractive materials, and spend that few minutes with family.
In her article, the author asserted that the age-old tradition of family coming together to dine-out and spend that time together has been interrupted by using phones, newspapers, magazines, etc on dining table.
To support her claim, she backed up by citing a research study printed in the 'Journal of Social and Personal Relationships', according to which the quality of having one-on-one conversation is declined due to phone usage. In the fifth paragraph, the author supported her claims by providing evidence of the research study in the printed journal, researchers point of view, and also the viewpoints by research subjects.
