USAPL National Referee Practice Exam

In this item the focus is on weight classes that are reserved for younger age divisions. Some men’s weight classes are designated specifically for sub-junior and junior lifters, meaning those classes aren’t open to the adult/open division. The standard open classes like 59 kg, 66 kg, and 74 kg are part of the open lineup and are not restricted to sub-junior or junior competitors. The 53 kg class is explicitly listed as sub-junior and junior only, so it exists solely for those younger divisions and is not an open class. That explicit designation makes it the correct choice among the options.
