You should be careful when reading the question though, because sometimes the requested redox reaction will be the reverse of what is listed in the table so you have to flip the sign before ordering them.
If you want more practice for this type of question 14.25 in the 6th edition of the book is a good resource. It gets confusing for me because you have to reverse the E value and understand if the question is asking for the strength as a reducing or oxidizing agent and whether it is asking the strength of (using Cu as example) Cu or Cu 2+

Don't recall if this particular type of problem was explicitly covered in class, but we should know this based on the information that Lavelle has given us. It is also in our homework which suggests we are expected to know it.
If you're looking for increasing oxidizing power, you need to see which elements have a higher chance of being reduced. In other words, you'd see which values have the highest standard reduction potential and are the most positive. If you're looking for increasing reducing power, you need to see which elements have the most negative standard reduction potentials.
