Read the given passage and answer the questions that follow.
Shikshayatan – a school started in 1994 at Arasavanankadu, a village near Kumbakonam in Tamil Nadu, with just 15 children by Mr. Raghavan, a chartered accountant, and his wife Aruna, an M.Phil in English – sets a model for both teachers and learners. The teachers here believe that learning is a form of play. They prove that learning can be made interesting and enjoyable. Most of the teaching material are produced by the teachers, who customise their teaching aids to suit their students’ needs and abilities. Health and nutrition of the children get priority. This ensures the children have the physical energy required for learning. Nutritional and medical supplements are provided to the needy. Free exercise and play are encouraged. Children learn spontaneously when their interest and curiosity are awakened. Teaching is confined to brief periods according to the natural attention span of each child, which is normally 15-30 minutes daily during the first two years. It is never extended beyond the child’s span of interest

2. B

3. C

4. D
