Which article of the Constitution of Pakistan obligates the state to provide free and compulsory education to children of the age group 5 to 16 years?

Ask questions is the best answer. Effective teaching involves active student engagement, and asking questions stimulates critical thinking, encourages participation, and helps the teacher assess student understanding. While lectures, homework, and technology can be valuable tools, they are not as directly indicative of a teacher’s ability to engage and inspire students.
