①If a child whose livelihood was maintained by the father or mother at the time of the death of the father or mother, who met the requirement of Article 42, item (i) of the National Pension Act, is, on August 1, 1965, in a state of disablement of the degree specified in the Appended Table of that Act as amended by this Act and is 18 years of age or older but under 20 years of age, then, notwithstanding the provisions of the main clause of that Article, the orphan's pension under that Article is paid to that child; provided, however, that this does not apply if the child falls under any of the following items:
