A study at UCLA investigated factors that might result in greater attention to the health and education of girls in rural India. One such factor is information about job opportunities for women. The idea is that if people know that educated women can get good jobs, they might take more care of the health and education of girls in their families, as an investment in the girls' future potential as earners. Without the knowledge of job opportunities, the author hypothesizes that families do not invest in women's well$-$being.

The study focused on $160$ villages outside the capital of India, all with little access to information about call centers and similar organizations that offer job opportunities to women. In $80$ of the villages chosen at random, recruiters visited the village, described the opportunities, recruited women who had some English language proficiency and experience with computers, and provided ongoing support free of charge for three years. In the other $80$ villages, no recruiters visited and no other intervention was made.

At the end of the study period, the researchers recorded data about the school attendance and health of the children in the villages.

Question $1.$ Which statement best describes the treatment and control groups for this study? Assign either $1,2,$ or $3$ to the name jobs$\_$q$1$ below.

The treatment group was the $80$ villages visited by recruiters, and the control group was the other $80$ villages with no intervention.

The treatment group was the $160$ villages selected, and the control group was the rest of the villages outside the capital of India.

There is no clear notion of treatment and control group in this study.
