please answer the two word questions in the last picture. thank you!

(Comprehensive Spreadsheet Problem 11-23 from the end-of-chapter question set) Your division is considering two projects. Its WACC is 10%, and the projects' after-tax cash flows (in millions of dollars) would be as follows: vs.. Find the internal rate of return with Excel's IRR function: We find the modified internal rate of return with Excel's MIRR function using the 10% WACC: We find the modified internal rate of return with Excel's MIRR function using the 10% WACC: \begin{tabular}{ll} MIRR A= & 16.50% \\ MIRR B= & 15.57% \\ \hline \end{tabular} roject A Discounted Pavback Period; \begin{tabular}{rc} Time period: & 0 \\ Cash flow: & (30) \\ Disc. cash flow: & ($30) \\ Disc. cum. cash flow: & (30.00) \\ Discounted Payback A: & 3.43 \\ \hline \end{tabular} Project B Discounted Pavback Period: \begin{tabular}{rccccc|c|} \hline Time period: & 0 & 1 & 2 & 3 & 4 \\ \hline Cash flow: & (30) & 20 & 10 & 8 & 6 \\ \hline Disc. cash flow: & (30.00) & 18.18 & 8.26 & 6.01 & 4.10 \\ \hline Disc. cum. cash flow: & (30.00) & (11.82) & (3.55) & 2.46 & 6.55 \\ \hline \end{tabular} Discounted Payback Pas B2.40 b. If the two projects are independent, which project(s) should be chosen? c. If the two projects are mutually exclusive and the WACC is 10%, which project(s) should be chosen? 5 fine far the two projects. Identify the projects' IRRs on the graph
