Explanation:

Adolescence is a phase of human life that begins around 11 years of age. This is the period of life in which the most apparent changes in the body occur due to hormonal changes. At this stage of life it is common to try to move away from the family, because it no longer satisfies them in relation to social interests. Individuals who enter puberty tend to behave slightly differently, beginning to contradict and disagree with their parents, they also tend to be taller and heavier than individuals of the same age who did not enter puberty.  Franca is showing these signs, so we can conclude that she is entering adolescence.
