Cоnsider the chаrt given belоw, lоok very cаrefully to understаnd what the chart is about and what its story is. Spend some time on this before you answer any questions below. Do not rush to answer questions before you examine the chart well. Judge it based on what it did versus what it intended to do. While doing that also think about alternative ways of achieving the very same, if any. Then, answer the questions. The chart requires eye travel.
