Maybe there's a language barrier, but I have no idea what you're asking or referring to.
There are Millions of things in the world with a "Lesson 2". You need to tell us more if we can give you a reasonable answer.
Lesson 02 of what?
What class are you taking - General SolidWorks, a specific subject in SolidWorks, is it for a certification test .....?
All we can determine so far is that (since you are on the SolidWorks forum) you are asking about something related to Solidworks that has a Lesson 02 in it.
The best lesson for you to Learn at this time is - if a stranger walked up to you and asked you a question, was there enough information in the question they asked for you to understand what they were asking for and for you to give them the correct answer for what they were needing.
This is one of the best lessons for life for you to ask yourself. If you asked yourself the same question you asked us, and you were in our place (not knowing you or what you were doing / studying) did you ask the question in a way for us to fully know and understand what you needed.
