I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "There are many similarities and differences among teachers around the world. In almost all countries teachers are educated in a university or college. Governments may require certification by a recognized body before they can teach in a school. In many countries, elementary school education certificate is earned after completion of high school. The high school student follows an education specialty track, obtain the prerequisite "student-teaching" time, and receive a special diploma to begin teaching after graduation. In addition to certification, many educational institutions especially within the US, require that prospective teachers pass a background check and psychiatric evaluation to be able to teach in classroom. This is not always the case with adult further learning institutions but is fast becoming the norm in many countries as security concerns grow."? 

What do some countries mandate that aspiring teachers successfully complete in order to teach?
