Answer:
The correct answer is letter "B" and "C": Keep an open mind; Separate facts from opinions.
Explanation:
At the moment of solving different-point-of-view issues, it is important to be open-minded, otherwise, we could only remain with our opinion discarding others' critic point of view that could be useful at the moment of taking decisions. Besides, it does not matter if other individuals are biased since we can separate the facts from those points of view. Separating the facts implies analyzing what others have to say in deep regardless of what their emotions can be about that matter. It implies subtracting an objective idea from a subjective point of view.
