Identify the following introduction as dialogue, anecdote, startling information, or all commentary:

It doesn't take a rocket scientist to know that students must start preparing for high stakes tests such as the SAT. The SAT plays such a significant role in the college application process, and this one test can determine a student's future goals and aspirations. There are various resources such as test prep courses and online materials that will help to prepare students for the tough road ahead, but it is up to them to take advantage of these resources as they begin to prepare.

A commentary is a sentence or even a whole paragraph or text in which we provide our own interpretation of something, which means it contains our opinion about that topic.

In the introduction we are analyzing here, the author is providing commentary concerning the SAT and students who prepare to take the test. It is the author's opinion that it is up to the students to take advantage of certain materials as they prepare.

We can eliminate dialogue, since we have no characters speaking to each other here. Anecdote is also wrong, since the author did not provide a story about an incident. Finally, we can also eliminate startling information, since the author is only providing information we already know.

With that, we can select commentary as the best option.
