I’m doing my Extended Essay on the effects on the city’s tourism of a music festival and all the smaller events it sponsors. I’m planning to mention how it gathers people and activates different economic areas, so it triggers economic growth in the region. My question would be ‘To what extent is the music festival effective at increasing tourism in the city?’ or something along those lines. Though I think it’s too broad and should be specified more. I appreciate any tips on how to make it more narrow or maybe approach the question in a different manner! Thanks.
