Economist: To the extent that homelessness arises from a lack of available housing, it should not be assumed that the profit motive is at fault.
Conclusion
Profit motive is not at fault for the lack of available housing that leads to homelessness.
Evidence
In general, if the market allows private investors to make a profit, housing will be provided. It's unrealistic to expect investors to take risks if they're not going to get benefit in return.
Evaluate
The easiest way to locate the conclusion here is two-fold: - any time we're reading an argument on Role or Main Conclusion, we should be priming our brain with a reminder that most of these conclusions are an opinionated first sentence or a rebuttal opinion.
The word “should” in the first sentence shows the opinion.
We verify that the first option is the Conclusion by using the Support Test: why should we believe that profit motive isn't to blame for the lack of affordable housing?
Because private investors would provide housing if the market allowed them to make a profit doing so, and it's unrealistic (unfair) to expect them to take risks with their property unless they get some benefit in return.
The question stem is asking us for the role of the intro to the first sentence, which was the Main Conclusion. What is the role of the into clause? It sounds like it qualifies the conclusion. It allows for the idea that profit motive might be at fault for other aspects of homelessness, but wants to say that profit motive isn't to blame for lack of affordable housing.
