If you look very carefully to the graph you can find the solution pretty fast.

I admit that the graph itself is distracting and seems a mess. However, the question is quite straightforward.

It asks you what % are lawyers of all members who compose the Congress.

The total numbers of members are 535. It is at the top of the chart.

Now, on your right, the lawyers are 215 at the Hour of representatives and 63 at Senate for a total of 278.

Now, the question is: Approximately what percent of the members of Congress are lawyers which means, translating words into math, $$278 = \frac{x}{100} * 535$$

$$\frac{27800}{535} = 51.9$$

$$D = 52 %$$ so is the right answer.

Hope this helps.

Regards
