Multiple choice

The popular perception is that allergy is not organic in origin and is caused by dust and other allergens that we breathe in. A recent report, however, shows that irrespective of the type of allergens - organic or inorganic - allergy has not much to do with extraneous factors. It is not the exposure or the risk of exposure, but the lack of exposure that is primarily responsible for children and adolescents falling prey to allergies of various kinds.

Which of the following statements best explains the apparent paradox regarding exposure?

  1. Limited exposure helps build up the immune system.

  2. Allergy is internal, not external.

  3. Children and adolescents should be exposed to clean and hygienic environs.

  4. Some of the allergens do not come from the air we breathe.
