Explain whether you would make a distinction between “pilgrimage” and “tourism”?

the author (Brent Plate) states that there is “no clear line between tourism and pilgrimage.” First, in just 50 words, answer whether you would make a distinction between “pilgrimage” and “tourism”? Explain your thoughts. Secondly, answer how Plate maintains that there is no division between tourism and pilgrimage, i.e. how are these two very different terms so alike that Plate can maintain a sort of unity between them? What makes a dividing line between “pilgrimage” and “tourism” so unclear for Plate?
