Before a craft fair begins, three groups of volunteers must do five projects- G, H, J, K, and L. Each project is done y exactly one group. Each group does at least one project and finishes all of its projects before the next group begins doing projects. The following limitations apply:
The second group does not do project J or project K. If the first group does project G, then the third group does project H. The group that does project H does no other projects. Project J cannot be done earlier than project L. Solution: Distribution Game. 1. J, K -> ~2 -> 1 or 3. 2. G1->H3 H1/2->G2/3 3. H is always alone. 4. ~J...L ___ ___ ___ 1 2 3 19. Which one of the following is a complete and accurate list of the projects, any one of which could be the only project done by the first group? (A) H (B) G, K (C) H, J, K (D) H, K, L (E) G, H, K Notice that H and/or K are listed in four answer choices. You can safely assume that they will both be in the correct answer choice. Therefore, focus on (C), (D), and (E). Use trial-and-error approach. D - is the right answer choice. Pay attention to the wording and use the strategy of commonalities and, only then, stat using trial-and-error approach.
