Answer:
The columnist is correct.
Step-by-step explanation:
Thought is that which is brought into existence through intellectual activity. For this reason, it can be said that thought is a product of the mind, which can arise through rational activities of the intellect or abstractions of the imagination. For this reason, we can agree with the columnist that thoughts are something voluntarily controlled and altered depending on the situation in which they are inserted.
An emotion is a set of chemical and neural responses based on emotional memories that arise when the brain receives an external stimulus. Emotions are not voluntarily controlled or modified, they arise involutely due to a situation. For this reason, we can conclude that the columnist is correct once again.
