<span>#1) What creature helps Gulliver to escape from Brobdingnag?
Answer: The creature that helped Gulliver escape from Brobdingnag after two years being there is a Giant Eagle who picked up the traveling box where Gulliver was in. After a while the Eagle realized that this box was not edible and dropped it in the middle of the sea where Gulliver was later picked up by a passing ship.
When on tour of the South coast of the Kingdom of Brobdingnag, Gulliver goes down to the beach with a servant. At this point, Gulliver really wants to go home, as it has been two years since he arrived at the kingdom. As Gulliver is relaxing in his box, a giant eagle comes and picks him up. the eagle eventually drops the box at sea, and Gulliver is rescued by some sailors who are his same size.
No improvement to this sentence is necessary. It makes perfect sense on its own and sounds right. "Either" always takes an "or" else the word wouldn't make sense, as it's meant to contrast binary options.
