Address them? I don't know what that means. Do you mean you need to identify them?

Question

Go through the sentence one word at a time and identify each word. In that way, you'll isolate the adjectives and adverbs. Then you'll be able to complete your assignment. I'll get you started; you finish and let us know what you come up with.

In - preposition
the - article
late - adjective, modifying "1990s"
1990s - number serving as a noun, object of preposition "in"
etc.

In the late 1990, the popularity of MTV's The Real World sparked increasingly interest in this concept.
