which factor is least likely to affect the results and interpretation of a functional mri?\n○ cancerous growth\n○ prescription medication\n○ a sinus infection\n○ caffeinated soda
Answer
# Brief Explanations:
A sinus infection mainly affects the nasal - sinus area and is less likely to have a direct and significant impact on brain activity measured by fMRI compared to the other factors. Cancerous growths can alter brain function and blood - flow patterns. Prescription medications can influence neural activity. Caffeinated soda can also affect brain metabolism and blood - flow due to the presence of caffeine.
# Answer:
a sinus infection
