Kelly, Lisa, Mark, and Ned are friends. One is a painter, another a doctor, another a lawyer, and another a salesperson. Each has a
hobby: their hobbies are tennis, jogging, poker, and gardening.
1) Lisa is the lawyer.
2) Mark is the doctor and his hobby is not gardening,
3) The painter's hobby is jogging.
4) Kelly's hobby is tennis.
Even if we did not know that Kelly's hobby is tennis, which of the
following statements could we deduce to be true?
1 Kelly is either the painter or the salesperson
2 Nancy's hobby is gardening
3 Mark's hobby is either poker or tennis

3.   Mark's hobby is either poker or tennis.

Explanation:

Kelly                    Lisa                Mark              Ned

salesperson      lawyer            doctor           painter

tennis              gardening         poker           jogging

1.   No, because we are told that the painter's hobby is jogging, so as the salesperson, Kelly doesn't jog.

2.  No, because we know that Nancy (Ned? Is this a typo?) likes jogging because she's (he's) the painter. (If this ISN"T a typo, then, of course, #2 is wrong simply because there is no Nancy.)
