How does gary golden spend most of his days studying

Answer :

Gary Golden spends most of his days studying transportation. He is interested in the science of how people move from place to place. He spends his time studying the relationship between cars, subways and trains. He makes sketches of cars, trains, subways and highways to explain his ideas about these means of transportation. He is most interested in understanding the way in which these relationships are going to change in the next twenty years in the future.

Gary Golden is a futurist, that is he analyzes the way the world is today (the present) and uses the information that he has to predict the way the world would be like in the future. Futurists believe that we can improve the decisions we make today by making scientific predictions about the future.

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.
