Answer:
Critical thinking
Step-by-step explanation:
Critical thinking is a process of deep analysis, evaluation, and synthesis of facts and evidence that will lead to the formation of well-thought jugdement.
In this case, Christina is not analysing in a critical way because she believes the first thing she hears/reads without evaluating the sources, evidence, and facts that lie behind the claim that "the consumption of orange juice triggers hyperactivity in children."
In order to form a judgement, she would have done research that provides evidence to this claim to actually accept it.
Therefore, the correct answer would be: Christima was NOT demonstrating critical thinking.
