The economy is doing badly.
Information
The economy is doing badly: We have a real estate slump that's been going on for a while. Car sales are at their lowest in years.
If real estate was looking goor or if car sales were looking good, then it would still be possible to say "the economy is healthy".
causal (X makes it quite probable that Y) pivot (But)
When real estate is bad and car sales are bad, it's quite probable that the economy is doing badly.
Evaluate
This gives us a couple facts about the current economy and then a couple considerations about whether we should conclude the economy is doing badly or not.
There aren't any obvious wording clues to go off, but the last sentence seems tempting. It has a Pivot, and we know that when Inference paragraphs use a Pivot word (like "but, yet, however, nonetheless) to introduce the final claim, that final claim almost always plays a .... [wait for it] .... pivotal role in the correct answer.
There is also some causal language in the final sentence, that having bad real estate and car sales at the same time is a strong indicator of bad economy.
Goal
It's hard to make any prediction here, so we'll just look for the most provable answer we can find, but our suspicions are that the final sentence will be important.
