input question: Extract the answer to the question from the following context. Question: Where is Washington Square located? Context: Philadelphia's central city was created in the 17th century following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long straight streets running east-west and north-south forming a grid pattern. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. The Delaware River and Schuylkill Rivers served as early boundaries between which the city's early street plan was kept within. In addition, Penn planned the creation of five public parks in the city which were renamed in 1824 (in parenthesis): Centre Square, North East Publick Square (Franklin Square), Northwest Square (Logan Square), Southwest Square (Rittenhouse Square), and Southeast Square (Washington Square). Center City has grown into the second-most populated downtown area in the United States, after Midtown Manhattan in New York City, with an estimated 183,240 residents in 2015.???

input question: Extract the answer to the question from the following context. Question: Which of the following is not a dog tail shape: straight, sickle, or Braque du Bourbonnais? Context: There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries. In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.???

input question: Extract the answer to the question from the following context. Question: What school was not meant for elementary school students? 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.???
