Hey Student!

Great question.

The question "what is the evidence for?" is another way of saying "what does this graphic show?

I ask myself this question as a way to understand the given graphic.  I'll first look at the title, which gives me a good idea about what this graph is about - perhaps the graphic is showing the relationship between students and the time spent doing homework. Then, I'll take a look at each axis - the X and the Y - to understand my variables. Perhaps my X-axis is art students and science students, and my Y-axis is time in minutes. Basically, understanding what the "graphic is evidence for" allows me to cross out wrong answers that are NOT indicated by the graphic. The reason I don't spend time discussing that in the answer explanations is because doing so will take too long. But it is a skill you want to develop. Sometimes a graphic can be overwhelming for some students because there is so much information and students don't know where to begin. Getting used to looking at the graphic one section at a time will help dissolve some of those fears and give you more certainty when answering a question. After you do this step, then the next step is determining whether an answer choice is supported by the graphic (does the graphic show evidence for an answer choice).

Hope this helps

Also, I just thought of a question to ask you: would you like a longer, more detailed course for SAT Reading? I was planning on creating an SAT Reading Mastery Course that would contain much longer explanations. I would also have videos that help to develop certain skills such as skim reading, summarizing main points, ideas, and how to think about and cross out wrong answers. Would this be something you would be interested in? =) Please let me know!
