Which sentence uses an objective tone and formal language?
a) the research revealed that cats, on average, sleep 50% more in a 24-hour period than dogs.

c) we believe that even though dogs do not sleep as much as cats, they still sleep a good portion of the day.
d) while our research didn't prove this, we believe that dogs eat, on average, more than cats during a typical day.

The answer to your question would be that the sentence that uses an objective tone and formal language is A.

Explanation:

A is the sentence that has an objective tone and formal language because of the choices of words selected (reveal) and the facts provided to back up the statement (the percentage). What is more, the statement is not biased, it does not contain any subjective information that may have to do with the personal opinion of the author (see B, C, and D).

third person

explanation:

note the usage of names and pronouns, "james" & "the old man". this alone can confirm it as third person, as first person uses "i" and the like, while second person uses "you" and the like.
