CONCLUSION: You’ll get a higher paying job if you buy a laptop!

- CORRECT. We don’t know if wealth causes laptops or laptops cause wealth.
- The conclusion could be true. It just doesn’t have to be.
- The conclusion is about the past. Read it again: “led to a higher paying job.”

While reading this question, I noted the bad causation. However, when reading C (the correct answer), I found it quite confusing, specifically the part that says “the first thing’s having caused the second.”
The first thing mentioned in the stimulus is laptops, the 2nd is wealth. Then in the conclusion it’s the same. So I eliminated this answer because that just is saying there is evidence that the conclusion is true. Was this too nitpicky? Any more tips/explanation on this? Thanks!
This is super tricky. The explanation is that the first thing and the second thing refer to the first and second things mentioned IN THE ANSWER.
I had to think about this for a while. Let’s rephrase C to make it clearer:
It concludes that high paying jobs (first thing) were caused by laptops (second thing) even though the first thing (high paying jobs) could be why people bought laptops (second thing)
Hope that makes sense! Grammatically first thing and second thing have to refer to what was mentioned in the same sentence, rather than the order they were mentioned elsewhere.
