Answer:to combine ideas from multiple sources
Explanation: synthesize basically means combine, so you need to combine ideas from different places and put them together as one.
Your first option, "I have taken all the stress I can stand.", is a line of dialogue.
Dialogue is speaking/talking. The second and last options cannot be examples of dialogue because they are not being spoken (you can tell by the lack of quotation marks).The third option is also incorrect because it is what is written, as it says "the study reported" (the study does not speak). Therefore, the first option is correct.
D. indirect characterization
Indirect characterization is when the author reveals the traits of a character by the way the character speaks, thinks, effects others, acts, and looks. In this excerpt the character's traits are shown through his generosity to the drivers. He gives them each a pack of cigarettes and informs them about what is planned. Direct characterization is when the author specifically tells the reader the character's traits.
