Music historian: In the past, radio stations would not play rock songs that were more than three minutes in length.
Statements
Rock songs used to be limited to 3 minutes to get played on the radio.
During that 3 minute era, rockers said, "you're stifling our creativity".
When the 3 minute limit was removed, some critics said, "Ah, now rock music has become artistic."
pivot (however) causal (when X happened, it became Y) causal (because)
Removing the 3 minute limit led to song structures breaking down and the music becoming aimless.
Being derived from certain style of music led to rock music's difficulty in making good songs of extended length.
Evaluate
When we read Inference paragraphs, we are hoping to find claims that can be synthesized, usually by finding some Overlapping Information.
And we read carefully for indicator wording that provides hints about what is being tested: - Conditional - Causal - Mathematical - Ends w/ Pivot
The last sentence is extra juicy here, because it is introduced with a pivot, "however" and contains two causal ideas.
When the last claim in an Inference paragraph begins with a pivot, it's usually a sign that our job is to reconcile that last idea with what came before it. Most of the time it will create some tension that forces a mathematical inference or triggers the contrapositive of some rule.
In this case, it's more like a Rebuttal. Some music critics were claiming that, . In other words, some critics think it was a good thing to remove the 3 minute limit.
Our author disagrees. She says that removing the 3 minute limit was a bad thing (song structures broke down and the music became aimless).
The final idea is suggesting, .
Goal
We don't know precisely what to look for, but we can anticipate that it will have the rebuttal vibe of,
