As we said, since the bar graph is drawn to scale, and since the bars start at zero, we can do some quick estimation to narrow down our choices. In 1969, more domestic ships were inspected than foreign ships (not too surprising, since that's true for every year on the graph). So the ratio must be more than one. The solid bar is considerably less than twice the length of the shaded bar, so we can see that the answer can't be choice (1) or (2). Reading from the top of the 1969 solid bar over to the left, we see that a little more than 12 thousand domestic ships were inspected. Reading from the shaded bar to the left, we see that around 9 thousand foreign ships were inspected. So the answer is a little more than the ratio of 12 to 9 , or a little less than $\(\frac{12}{9}\)$. Since, $\(\frac{12}{9}\)$ can be reduced to $\(\frac{4}{3}\)$, choice 5 is best.
