The correct answer to this open question is the following.
Although there are no options included, we can answer the following.
Our text suggests an emphasis on three types of activities for enrichment programs. One is exploratory activities, the second is individual and small group investigations of real problems, and the third type of activity is group training activities.
These kinds of examinations are going to enrich the student experience and are going to allow us to know them better. Exploratory activities help teachers to get some information on general issues and recognize possible wants, talents, and opportunities for each student. With the investigation of small but real problems, the information collected would serve to give us a specific idea on how students react and develop critical thinking to come up with solutions. In group training activities we can see how students relate to each other and can work in teams, applying what they learn.
