Step-by-step explanation:
The statement that a moka is a form of marriage practiced by the Kawelka in Papua, New Guinea is false.
A moka is not a form of marriage, but rather a traditional exchange system practiced by the Kawelka people in Papua New Guinea. In a moka, individuals or groups exchange valuable items such as pigs, shells, or money to establish social relationships and build alliances, rather than formalize marriage. The documentary 'Ongka's Big Moka' provides insights into the moka tradition among the Kawelka.
