Ascientist is giving a presentation on the milky way at an astronomy conference. how will the composition of her audience affect the information she includes in her presentation? she should address her audience as beginners by discussing the basics about the topic in a straightforward way. she should address her audience as experts by reporting the results of her research without providing basic information or defining simple concepts. she should pick a narrower topic that is appropriate for an astronomy convention. she should prepare a presentation for a general audience by providing some standard information and by defining concepts without oversimplifying.

I believe the correct answer is "She should prepare a presentation for a general audience by providing some standard information and by defining concepts without oversimplifying.

The two phrases that best describe the purpose of including character details in your story are:

4: To help the reader visualize the characters.

2: To make the story more interesting.

Explanation: Character details such as "Susan's' beautiful red hair bellowed in the wind" or  "Balthazar awoke to find he was somewhere underground. he ruffled his fluffy. brown hair and tried to figure out what had happened. All he knew right now, were that his six-pack abs extremely sore"  

Help the reader to visualize the characters. Balthazar has fluffy brown hair and six-pack abs (lol) and Susan has long red hair.

It also makes the story more interesting. I'm not gonna explain that one, because my fingers are cold, and it's getting hard to type.

I hope this helps! Happy holidays!
