Problem number two. Which figure shows a part of this necklace? Let's look at the pattern of the beads in the necklace first. We have two white beads here with just one black bead in between, then two gray beads, one black bead, two white beads, one black bead, two gray beads, one black bead. Our answers show three beads in each part, but nowhere are there any two beads of the same color next to each other. The only way that can happen in our necklace is if there's a black bead in the middle with a white bead on one side and a gray bead on the other, like this, or with the white bead on this side. Otherwise, there have to be two gray beads or two white beads shown to a black bead. Out of the answers listed, the only one that does this is C. Now let's look at the other answers. In answer A, we have one white bead between a gray and a black bead. This does not happen in our necklace because two white beads are always next to each other. In answer B, there's a black bead surrounded by two white beads. In the necklace, there's no place where there's a white bead on each side of a black bead. Answer D does the same thing with gray beads, so again, we never have that. We do not have a black bead with a gray bead on either side. And in answer E, there's just one bead between two black beads. Again, in the necklace, two white beads are always together, so they can't be just one white bead between different beads. The correct answer is C.
