Question

[125]. Read the following passage carefully and answer the question.

Passage: The human immune system is an army without a single general. Skin and mucous membranes form the first wall, stopping most invaders before they enter. If a germ passes that wall, white blood cells attack it, and some of them remember the invader so that a second attack is met faster and more strongly. This memory is the principle behind vaccination: a weakened or harmless form of a germ trains the system without causing the full disease. The system must also learn restraint. When it attacks the body's own tissues, or overreacts to harmless dust and pollen, the result is allergy or autoimmune disease. Health, then, is not merely the absence of germs; it is a trained balance between attack and tolerance. Which of the following can be most reasonably inferred from the passage?

1.
The passage suggests the subject is unimportant and deserves no further attention.
2.
The passage proves that every traditional practice connected with the subject should be abandoned.
3.
The human immune system has a lasting importance that goes beyond its immediate or obvious effects, and understanding it changes how we judge related choices.
4.
The passage claims that only experts, never ordinary people, can understand the subject.
