I REALLY NEED HELP WITH THESE TWO QUESTIONS

What can you use to show the similarities and differences between what two authors have written on the same topic?

a pie chart

a bar graph

a Venn diagram

a timeline

What strategy would you use to recognize the differences between how two authors present the same information?

comparing and contrasting the texts

waiting a while between reading the texts

reading a summary of the texts

creating an outline of the texts
