There is one verb tense error in this paragraph. correct it:

that said, the first truly accepted take-off and flight powered by nothing other than the pilot himself, occurred almost fifty years later in november 1961, when derek piggott flies the sumpac ( southampton university’s man powered aircraft)a then world-record distance of 650-yards (594m).

The verb tense error in the paragraph is: flies

That said, the first truly accepted take-off and flight powered by nothing other than the pilot himself, occurred almost fifty years later in November 1961, when Derek Piggott flew the SUMPAC (Southampton University’s Man Powered AirCraft) a then world-record distance of 650-yards (594m).

The verb "flies" should be in past-tense because throughout the paragraph all the verbs are in past tense, indicating that an event has already occurred. Therefore, it should be replaced with the word "flew."

answer: buck is a dog living a charmed life on the estate of judge miller, during the time of the klondike gold rush in 1897. he is the king of all the animals on the estate and as such enjoys special privileges, such as the run of the estate and the admirable position of being the judge's favorite dog.

this all ends the day he accompanies manuel on a walk through the orchard to a flag station, where manuel sells him to a stranger. manuel sells buck, because he has gambling debts he needs to pay and a family to support.

this one act changes buck's life irrevocably. it is the catalyst for the rest of the story about buck and his transformation from domestic pet to wild animal.
