I considered doing that but it would cause confusion and break the quiz, as in Pakistan and many other countries, last names are not family names specific to a family, like "Jones" or "Anderson". Here, first names are considered the name, and if I considered last names as the name, then almost a half of the population would have Khan as their name. In this quiz (spoiler alert) there are 4 Khans, and if i turned on the "Is Name?" feature, then if you type Khan, all three answers would be guessed. I hope you understand.
