Hi everyone,

I just finished taking an online test and found out that some of my answers were wrong. The questions and answers can be found in attached screenshots.

Can you please point out where they went wrong and how to correct the mistakes? I don't have a single clue on how to do the first question. Can someone please tell me the steps maybe with an example?

Please help!

Thanks in advance
