Question: Extract the answer to the question from the following context. Question: Why do children learn more in a class setting, other than group discussions, emulation, and competition? Context: In the medieval Islamic world, an elementary school was known as a maktab, which dates back to at least the 10th century. Like madaris (which referred to higher education), a maktab was often attached to an endowed mosque. In the 11th century, the famous Persian Islamic philosopher and teacher Ibn Sīnā (known as Avicenna in the West), in one of his books, wrote a chapter about the maktab entitled "The Role of the Teacher in the Training and Upbringing of Children," as a guide to teachers working at maktab schools. He wrote that children can learn better if taught in classes instead of individual tuition from private tutors, and he gave a number of reasons for why this is the case, citing the value of competition and emulation among pupils, as well as the usefulness of group discussions and debates. Ibn Sīnā described the curriculum of a maktab school in some detail, describing the curricula for two stages of education in a maktab school.

Question: Extract the answer to the question from the following context. Question: What features does bamboo have that people mistakenly call it wood? Context: Structural material that resembles ordinary, "dicot" or conifer wood in its gross handling characteristics is produced by a number of monocot plants, and these also are colloquially called wood. Of these, bamboo, botanically a member of the grass family, has considerable economic importance, larger culms being widely used as a building and construction material in their own right and, these days, in the manufacture of engineered flooring, panels and veneer. Another major plant group that produce material that often is called wood are the palms. Of much less importance are plants such as Pandanus, Dracaena and Cordyline. With all this material, the structure and composition of the structural material is quite different from ordinary wood.
Answer:
material that resembles ordinary, "dicot" or conifer wood
