Answer:
Gertrude's favorite is <em>George Burn</em>
What we know from the beginning:
<u>Comedians</u>:
- George Burn
- Jack Benny
- David Letterman
- Jerry Springfield
<u>Lucy</u>: Jerry Springfield is her favorite
<u>David</u>: Does not like David Letterman
<u>Gertrude</u>: Does not like David Letterman, Does not like Jack Benny anymore
Solving:
- Since we know that <em>Jerry Springfield is Lucy's favorite</em>, he is not longer an option. This leaves George Burn, Jack Benny, and David Letterman.
- David and Gertrude do not like <em>David Letterman</em>, so he must be <em>Jose's favorite</em>. This leaves George Burn and Jack Benny
- Gertrude does not like Jack Benny anymore, so the only one left to be <em>her favorite is George Burn</em>
