Question 19 is based on the passage you have just heard.

    Three years ago, Puncha Maya, her husband and five children lived in a shaky flat in southern Nepal. Every morning, the parents walked the dirt roads seeking work in the rice fields. (19) After the harvest, the family went begging for food. Today, the Mayas own a small paper-bag making company. With the money they've earned, the Mayas have purchased a small plot, on which they grew vegetables and raise goats for additional income. In fact, the family has saved $ 68, this is remarkable in a country with an average annual income of $ 160.

    Grace Mbakwa, her husband and eight children once lived hand-to-mouth in Cameroon. Today, the Mbakwas run a clothing manufacturing business and own a home. (20) They are able to send their children to school, at a cost of annual sum of $ 2,800.

    The idea of starting her own business seemed impossible to Pilar Moya, a poor woman from Atahualpa, high in Ecuador's Andes Mountains. Today, however, she is one of the proud owners of a bakery specializing in sweet cakes.

    (21) These businesses are part of economic revolution sweeping to developing world. The sponsor is the Trickle Up Program, a non-profit organization founded by New Yorkers Glen and Mildred Leet. This organization offers people like the Mayas, the Mbakwas and the Moyas modest $ 100 grands. Since 1979, the program has helped over 130,000 of the world's neediest people in 90 countries win small life-saving victories over poverty. And it has turned conventional thinking about foreign aid on its hand.

(19). What do we learn about Puncha Maya's family of three years ago?

解析：A。本题为细节题。问题为：我们可以了解到三年前的玛雅家庭什么信息？根据原文“After the harvest, the family went begging for food.”可知玛雅家族每次收获后，会去乞讨，故正确答案选A。
