Question

which source is most likely an authority on the subject? dr. vale, a pediatrician, discusses electrical circuitry on her home - improvement website. jonah, an amateur cook, teaches his son how to make the best grilled cheese sandwiches. susan, an architect, presents her hand - made quilts at the quilting society. dr. patel, a cardiologist, presents her findings on heart disease.

Explanation:

A cardiologist is a medical expert in heart - related matters. Dr. Patel, being a cardiologist, is most likely an authority on heart disease. A pediatrician discussing electrical circuitry is outside their medical expertise, an amateur cook teaching about a recipe is not an expert in a formal sense compared to a medical specialist, and an architect presenting quilts is not related to their professional architectural expertise.

Answer:

Dr. Patel, a cardiologist, presents her findings on heart disease.
