Final answer:
Huck feels uneasy at Mrs. Loftus's house because his disguise as a girl is being tested, he fears being discovered and losing his freedom.
Step-by-step explanation:
The question refers to Huck feeling uneasy at Mrs. Loftus's house in the novel The Adventures of Huckleberry Finn. Huck is uneasy because he is in disguise as a girl and is afraid that his true identity will be discovered. The unease is further heightened by his interaction with Mrs. Loftus, who is testing his disguise and eventually figures out he is not who he claims to be.
Huck is concerned about maintaining his freedom and avoiding being caught and sent back to his abusive father or the widow who wants to 'sivilize' him, contributing to his discomfort.
Huck feels uneasy while at Mrs. Loftus's house for several reasons. One reason is that Mrs. Loftus suspects that he might be a runaway boy. This makes him anxious and afraid of being discovered. Another reason is that Mrs. Loftus is very observant and asks him detailed questions, making him uncomfortable and forcing him to create false stories to hide his true identity.
Additionally, Huck is not used to living in a civilized environment and feels out of place and restricted in the strict and proper atmosphere of Mrs. Loftus's house.
