Last year , when I stopped carrying an umbrella it rained so rarely , my allergies were hardly noticeable . This year , uh . Mold is # 1 with a bullet on the allergy list ( dust is # 2 ) , although there are also some autumn spores that get me .
According to the above context, answer the following question.
Why is mold # 1 with a bullet on the allergy list ?


Because mold activates the writer 's allergies .
