Which code snippets should you include in Target 1 and Target 2 to complete the code? (To answer, drag the appropriatecode snippets to the correct targets in the answer area. Each code snippet may be used once, more than once, or not at all. You mayneed to drag the split bar between panes or scroll to view content.)

3. You need to ensure that resuming the app displays the required information.
