Ok, @helpplz, you’re new (welcome), so I’ll explain:
1. In general the people on this site have an aversion to doing other people’s homework for them. Many of us believe that students should do their own learning.
2. @janbb gave you the right answer. Perhaps you should look at the line that comes right before it, for starters.
3. @Sarcasm‘s points, though perhaps not gently put, are apt.
4. Your teacher is interested in what it means to you and not to a bunch of random folks online.
Sorry, but that might be all you’re going to get here.
P.S. The words in red and underlined are links.
