 Perhaps it was his own lack of adequate schooling that inspired Horace Mann to work so hard for the important reforms in education that he accomplished. While he was still a boy, his father and older brother died, and he became responsible for supporting his family. Like most of the children in his town, he attended school only two or three months a year. Later, with the help of several teachers, he was able to study law and became a member of the Massachusetts bar, but he never forgot those early struggles. While serving in Massachusetts legislature, he signed a historic education bill that set up a state board of education. Without regret, he gave up his successful legal practice and political career to become the first secretary of the board. There he exercised an enormous influence during the critical period of reconstruction that brought into existence the American graded elementary school as substitute for the older distinct school system. Under his leadership, the curriculum was restructured, the school year was increased to a minimum of six months, and mandatory schooling was extended to age sixteen. Other important reforms included the establishment of state normal schools for teacher training, institutes for in-service teacher education, and lyceums for adult education. He was also instrument in improving salaries for teachers and creating school libraries. Mann’s ideas about school reform were developed and distributed in twelve annual reports to the state of Massachusetts that he wrote during his tenure as secretary of education. Considered quite radical at the time, the Massachusetts reforms later served as a model for the nation. Mann was recognized as the father of public education.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50:

Milpa Alta is a region of twelve villages and towns to the south of Mexico City. In Milpa Alta, traditions are still very important and one of the most famous traditional events is a community meal. It takes place every Christmas and is called La Rejunta. More than a meal, it’s a feast, where about sixty thousand tamales and fifteen thousand litres of hot chocolate are made and consumed. Tamales are made from corn. They are typical of the region: the name Milpa Alta means "High cornfield". The feast is offered to the people who go on the long walk to El Señor de Chalma about 80 kilometers away. It’s an important event on the religious calendar for local people and as many as 20,000 people take part.

The planning and organisation of La Rejunta takes the whole year. Every year, different people are given the job of majordomo, which means they’re responsible for organising the meal. There’s a waiting list for the opportunity to do this and currently the next available year is 2046. This year’s majordomos are Virginia Meza Torres and her husband Fermín Lara Jiménez, who put their names on the list 14 years ago.

One year before the meal, men go to the forest and collect wood that they store near the home of the majordomo. It has to be dry when it’s used to make the cooking fires. Local farmers grow most of the corn, meat and vegetables that are needed as ingredients. In the week before the feast, hundreds of volunteers arrive to help with the preparation and the cooking. No instant or ready-made foods are allowed. Amazingly, everyone seems to know what they have to do. On the day of the feast, the majordomos and others have stayed up all night cooking. Fermin is in charge of the numbers–making sure there are enough tamales for everyone.

For the people of Milpa Alta, eating together is one of their most important traditions. One woman, Josefina García Jiménez, explains that sitting together at the table is like a glue that keeps people together. "It feels like I am passing down a tradition, and when they are adults, they will remember what I have done. Here we have time to cook, time to think about the ingredients, time to show our kids through cooking that we love them." The time that everybody stays at the table after the meal has finished is just as important as the food.

They talk, tell stories and laugh together. At Christmas, La Rejunta is a giant version of a family meal.
