557 - Logical Reasoning

Is it wrong for doctors to lie about their patients' illnesses? Aren't doctors just like any other people we hire to do a job for us? Surely, we would not tolerate not being told the truth about the condition of our automobile from the mechanic we hired to fix it, or the condition of our roof from the carpenter we employed to repair it. Just as these workers would be guilty of violating their good faith contracts with us if they were to do this, doctors who lie to their patients about their illnesses violate these contracts as well, and this is clearly wrong.
The conclusion of the argument is best expressed by which of the following?

1. Doctors who lie to their patients about their illnesses violate their good faith contracts with their patients.
2. Doctors often lie to their patients about their illnesses.
3. Doctors are just hired workers like mechanics and carpenters.
4. It is wrong for doctors to lie about their patients' illnesses.
5. Doctors, like mechanics and carpenters, enter into good faith contracts with us when we hire them.
