Which of the following is the best analogy for the process by which minimal contact with an allergen can cause a major reaction?
A) People with unhealthy diets are more susceptible to diabetes and high blood pressure.
b) Because minor earthquakes can weaken the existing infrastructure in an area, a series of minor earthquakes can sometimes lead to more damage than a single major earthquake.
c) Peanut allergy sufferers should avoid all potential contact with peanuts.
d) A student who fails a test can still earn a good grade if she works hard for the rest of the semester.
e) Drivers who speed regularly are more likely to be caught than those who speed only occasionally.
