Explanation:

1:

The phrase "Jorge reviewed his notes about global warming before presenting to the class" tells us that the topic of Jorge’s presentation is "Global Warming” (a gradual increase in earth’s overall average temperature because of the increase in greenhouse effect). The students also had to discuss this topic and ask questions from Jorge after his short presentation.

2:

"share their findings with the class" shows that Jorge’s audience is his class. The primary audience and main focus of Jorge’s presentation is his class, however their teacher Mrs. Herbert would also be present as an observer and for final evaluation. So he has to prepare his presentation keeping both (students and teacher) in mind. He has to explain all the concepts and technical terms considering his class level.  

3:

"after his short presentation, the class would ask questions and discuss" this phrase shows that the purpose of the discussion is to share the knowledge and improve students' presentation skills. First they have to do a proper research and include relevant, clear and correct content in right order. They will also get a chance to explain some difficult concepts and topics.  

4: Level of Formality

We choose highly formal style when talking to unknown audience or during job interviews, writing academic essays, presentations or letters to someone whom we don’t know personally.

We select semi-formal style when talking to well-known individuals, like our teachers and elders,  

And we use informal style only with our very close friends with whom we usually spend a lot of time, like class mates, team mates etc.
