Answer:
D). By eliminating emotional language used to describe the charity work.
Step-by-step explanation:
Objectivity is characterized as the factual and truthful representation of a situation. Such a description is free from any kind of involvement of author's personal opinions, bias, or feelings.
The most appropriate way to enhance the objectivity in the given paragraph is 'to eliminate the emotional language that has been employed to describe the charity work' as the use of descriptive words like 'tirelessly', 'obvious', 'impressive', etc. reflects author's personal opinion and prejudice towards Garcia Ruiz. Thus, the removal of these words would help offer an actual and objective description of her work and leave it to the audience to decide rather than imposing a pre-defined opinion(of author's own) to them. Thus, option D is the correct answer.
