An article headline claimed that "Drugs Cause Homelessness" due to a positive relationship found between homeless populations and drug use. Educated psychologists thought this might be flawed, because they thought unemployment was influencing both drug use and homelessness. The impact of unemployment on both is an example of:

1.a confounding variable
2.an illusory correlation
3.a negative correlation
4.a reverse correlation

3.a negative correlation
