Question

Tom believes that ---


Gatsby disabled Myrtle.


Myrtle disabled herself.


Wilson disabled Myrtle.


Daisy disabled Myrtle.

Answer 1

Do you mean Tom Buchanan (from The Great Gatsby)? And do you want a plain English answer, a justification from the novel, or a formal/logic representation (e.g., belief operator B_t(...))?

If you mean Tom Buchanan and want the plain answer + brief justification from the novel:
- Tom believes that Gatsby disabled (killed) Myrtle. — yes. After the accident Tom points Wilson toward Gatsby and frames Gatsby as the driver/owner of the car.
- Tom believes that Myrtle disabled herself. — no.
- Tom believes that Wilson disabled Myrtle. — no.
- Tom believes that Daisy disabled Myrtle. — no (Tom knows or suspects Daisy was involved but he deliberately blames Gatsby and does not acknowledge Daisy as the responsible party).

If you want these as formal belief statements, I can write them as B_t(Gatsby disabled Myrtle), B_t(Myrtle disabled herself), etc. Which output do you want?
