APPLICATION / ANALYSIS
Q12. A student experiences sneezing, itchy eyes, and a runny nose every year specifically during the spring pollen season, but has no symptoms the rest of the year. Explain, using your understanding of allergies, what is likely happening in this student's immune system during pollen season.
