Final answer:
The Second Wave immigrants, including Mexicans, took a range of jobs in the United States, including both unskilled labor positions and skilled labor and professional positions.
Step-by-step explanation:
The Second Wave immigrants, specifically Mexicans, took a variety of jobs in the United States. Many of them ended up in unskilled labor positions, such as restaurant and hotel work, lawn care, and janitorial work. This is because about one-third of immigrants over the age of 25 lacked a high school diploma. However, it is important to note that immigrants also held skilled labor and professional positions, like skilled laborers, professionals, intellectuals, artists, political leaders, and religious figures, depending on their individual backgrounds and qualifications.
