Answer:
"Alex Gómez was unkind and dishonest."
All the other options are facts clearly stated in the excerpt, this one could count as only a personal opinion.
Boolean searching:
Most searches will return too many or too few records. It takes a long time to look at hundreds of records. By putting a little effort into constructing search strings (what you type into the search box) you can save a lot of time. The database can do a lot of work for you if you take the trouble to add a little sophistication to your search strings.
To do this with databases you need to know about the Boolean system. By the use of a few simple linking words, called operators, you can make your searches much more precise.

The second-person “you,” likening the reader to a trusted confidant. The final line of the flashback portion of the novel is “God, I wish you could’ve been there,” suggesting Holden’s loneliness would have been relieved by having a friend like the reader with him during his experiences. The second-person address also draws attention to Holden’s unreliability as a narrator. Throughout the novel, Holden tries to convince the reader to interpret events one way while simultaneously presenting evidence that the opposite interpretation is correct. For example, he frequently insists how well he knows people – “The thing is, you didn’t know Stradlater. I knew him,” or “I know old Jane like a book.” However, his interactions with Stradlater, and his reluctance to contact Jane, suggest he is neither as intimate nor comfortable with them as he’d like the reader to believe. He also makes several references to how much he hates movies, and thinks his brother D.B. is a “prostitute” for writing for them, yet he mentions going to the movies several times. In these ways, Holden’s attempts to control the reader’s impression of him end up revealing who he really is.
