Bob has an unknown liquid and must determine what it is. he decides to systematically use a number of tests to determine the correct answer. according to piaget, bob has most likely reached the stage of cognitive development.

The Formal Stage

Explanation:

The Stages of cognitive development are as follows:

The Sensorimotor Stage, which is what babies go through, and consists of touchy-feely actions. The name comes from "Sensor" (feelings, nerves) and "Motor" or actions and movements.

The Preoperational Stage is when younger children begin to develop reading and writing skills, along with speech and recognization skills.

The Concrete Operational Stage is where kids start thinking more logically, instead of pretend situations. For example, a boy might understand a dog will play with him if he is calm and collected, instead of when he is rough and loud, thus scaring the dog away.

The Formal Operational Stage is when older kids start to make more logical conclusions through running tests and collecting data in a organbized way. This is when the child begins thinking like an adult.

Based on the information given, Bob best fits the 4th stage, Formal, because he chooses to do systematic tests to find what the liquid is.

na idade média, existia o santo ofício, responsável pela censura. hoje em dia, em um país democrático, temos algo que se assemelha a essa medida que é quando o governo impõe censura a um indivíduo ou meio de comunicação.

por constituição:

"art. 5º da constituição federal - inc. ix - é livre a expressão da atividade intelectual, artística, científica e de comunicação, independentemente de censura ou licença;

liberdade de expressão a garantia assegurada a qualquer indivíduo de se manifestar, buscar e receber ideias e informações de todos os tipos, com ou sem a intervenção de terceiros, por meio de linguagens oral, escrita, artística ou qualquer outro meio de comunicação. "

esse direito da constituição, quando contrariado, é o mais próximo ao julgamento político de obras e ações da antiguidade.
