I'm not sure I understand the purpose of the question and how we are supposed to answer.    The first paragraph makes a statement that we are supposed to agree with. Well, who is saying it is important to "hold on" to old traditions?   Why does this make it an important part of multiculturism.

Perhaps the question depends on where you live. Here in the United States we have a long tradition of "multiculturism" - good and bad. I think everyone, regardless of what generation they are, has some sort of interest in their heritage - and individual traditions that they maintain.

Traditions are "living" events and customs. Traditions change with the time - they are not meant to be looked at on a shelf.
