Answer:
The answer is: Gulliver expresses frustration about the fact that Sympson has edited his text
Step-by-step explanation:
The main concern of Gulliver through the beginning of his letter is to inform Sympson of his dislike for the version that he has published of Gulliver's travels. This is made evident by Gulliver himself by telling Sympson that he has published a "very loose and uncorrect" account of his travels and that he does not remember that he gave Sympson "power to consent that anything should be omitted and much less that anything should be inserted"
