  • Там нет cause

  • Точно, нет, но напрашивается. Вера, вы же сами написали, что текст с ошибками. Возможно, уважаемый автор что-то напутал или пропустил.
    С другой стороны, из предложенных слов вроде бы ни одно не подходить под контекст предложения, которое начинается со слова TODAY.
    Слово OCCUR можно было бы применить, но тогда надо было бы изменить предложение так " Today smog also refers to a condition that OCCURS when sunlight acts on the exhaust gases from automobiles, homes, and factories".
    .
    Кстати, второе предложение могло бы звучать и так" The term was first used to describe
    the__pollution_ __ of smoke and fog that sometimes hangs over London and
    other___substances ___ with high humidity."
