First, describe what the difference is between typography and typefaces.
Typography is more of the art of using typefaces effectively. Typefaces are fonts, basically. The main point is that you can do a lot of creative things with typefaces and typography is not just simply using the typeface, but using it in a way that makes your work unique.
Second, describe what you think Keedy means when he says "There is no such thing as a bad typeface...just bad typography."
He means that anyone can use a typeface but only someone skilled in typography can make it look good. People believe that old typefaces are bad because they have been used and cannot be unique any longer. However, a skilled typographer can use old fonts and create unique work.
Third, pick out a sentence or section from Helfand or Solomon that interests you. Describe what it is that draws you to this particular idea.
"The sensitive application of punctuation in even the most commonplace unit changes the entire feeling of a design." pg 287
This is only one sentence of the paragraph that intrigued me. The main point is that puncuation can make certain everyday things such as phone numbers easier to read. Solomon states that using a period instead of a dash makes the number easier to read. I found this strange because it is a commonplace to use a dash when typing/writing phone numbers. I believe this is because the period already has a number of defined usages.
