Hey man, I got caught out by T7S4Q35 in the BB. I went for B as I figured a dash is the same as a colon (since cirrected). E is a pretty easy answer to spot in hindsight, but my Q is, what does one need to know about dashes in the SAT?
You don’t need to know much about dashes on the current SAT. (The new SAT is a different story.) Generally speaking, unless it’s a comma or a semicolon in the context of a run-on or fragment, you can pretty much ignore punctuation.
