Which part of "second sentence" was confusing to you?

If it was the "second" part, then a workable definition would be that if you take a set of items, the second item is the item that is next in line after the first item in the set.

If it was the "sentence" part, you can find the second one by looking for periods in the piece I quoted. Parse the string until you find the first period, which will appear as a small black dot following one of the letters. Look closely, they can be hard to see. The second sentence, the one that I explicitly was asking about, begins immediately after that dot. Another way to identify the second sentence, since that period is so hard to see, would be to look for capital letters. Be cautious, though, because capital letters are not only used at the start of sentences, so you still have to look for that period to positively identify where one sentence ends and another begins.
