Answer:
El equipo positivo ha expresado su desacuerdo con el argumento del otro equipo y sus opiniones finales delante del juez.
Step-by-step explanation:
The use of the present perfect in Spanish is equivalent to the use in English. It is used to indicate that the action or event will take place in the past but still applies to the present. It is very common to see this form in the questions "Have you ...?"
The positive team has expressed their disagreement with the other team's argument and their final opinions in front of the judge.
