The three correct answers that help develop the theme of perception versus reality in the text are:
- Gortsby believes that the absence of a bar of soap means that the young man’s story is untrue.
- Gortsby finds the soap and concludes that the young man’s story was true.
- Gortsby interprets the man’s actions as a performance intended to create sympathy.
These events illustrate the contrast between Gortsby's initial judgment based on his perception and the reality of the situation as it develops.
