D. Logic at a National Park

Grace, Roberto, and Peter visited the National Park on a field trip. Each had a different favorite activity at the park (wildlife movie, fossil collection, or nature display). Each liked a different location at the park (the quarry, the excavation, or the river bluff). Each bought a different lunch (chili, hamburger, or soup). Read these clues to see who liked what best.

  1. Grace bought a hamburger for lunch, and Peter enjoyed the movie.
  2. The boy who loved fossils and the quarry talked to the park ranger.
  3. The boy who ate chili and likes the river bluff wrote notes in his book.
