Final answer:
The last two sentences provide evidence that supports the point made in the first sentence.
Step-by-step explanation:
The last two sentences in the passage provide evidence that supports the point made in the first sentence. The first sentence states that teens who work a lot are more likely to get involved with alcohol and drugs. The second sentence explains that those who work long hours may turn to substances as a quick release from stress. The third sentence adds that teens who have money are also more likely to engage in drug use. Therefore, the relationship between the last two sentences and the first is that they provide reasons and evidence that support the point made in the first sentence.
