Solution

1.B. irreversibility

Irreversibility is one of the characteristics of behaviorist Jean Piaget\'s preoperational stage of his theory of child development. It refers to the inability of the child at this stage to understand that actions, when done, can be undone to return to the original state.

2. C. overregularization

Overregularization is a part of the language-learning process in which children extend regular grammatical patterns to irregular words, such as the use of goed for went, or tooths for teeth. Also known as regularization.
