Author Lauren Tarshis writes, “But is it possible that some foods are too delicious?” What literary device is she using? *

Rhetorical question.

Explanation:

In her informative essay "Are These Chips Too Delicious?", writer Lauren Tarshis delves deep into the making of the perfect taste of food and juices for our consumption. The underlying process of how the foods we consume in our everyday lives takes a great deal of expertise and "scientists" working to perfect it.

Towards the end of the essay, she asks a rhetorical question "But is it possible that some foods are too delicious?" This question brings to mind if the foods that we eat are given too much of effort and tasting, that they seem to encompass the health requirements. Rather, they seem to be the least healthy for our consumption. And that seems to be the major motive of these food companies, to make health complications so that other companies like the medical and health insurance will have their fair share of profit in treating the people.

"it's more of an essay than story, but perhaps it is best described as a mood-piece: it uses a lot of musical imagery, not to mention sea imagery, religious imagery, and any other imagery that suits his purpose."
