Ok, so Google (without the quotes) “tale of two cities mob”. Scan the first few results – do any of them look like maybe they have helpful hints as to where in the book you’ll find the mobs? Perhaps a pdf by a website that is owned by the company that almost definitely makes the textbook your teacher got this question from? Yes? Good. So then on the left-handed side of that screen (click “quick view” in Google so it’ll open in Google Docs), you can see a little search bar, and it’ll say “tale of two cities mob”. Remove all the words but “mob”, so that you can find the part you want, and search for that. Then it takes you to the part of the pdf with the word “mobs”, and you’ll see a paragraph with phrases like “an English mob follows the [blank] of a [blank blank].” (Blanks are mine, obviously). Under that is a table where one column is the French mob, the other column is the English mob. It has a couple adjectives filled in for each. SCORE!!!
So, then you go to Google Books and search for “Tale of Two Cities” (with or without quotes, but I prefer without). Then choose the first option (because it’ll show you the entire thing, being free and not just a long preview). On the left side, under the book cover icon thingy, there’s a search bar for searching inside the book. Type in one or two of those adjectives, and search – even if he used the word 10 times, that’s only 10 possible page options down from a few hundred. If you can figure out which one will be the mob scene just from those small previews, awesome, if not, click on each option till you figure out which one you need. Then it’ll open up the page, and you can read the few paragraphs above and below it, where your descriptions will almost definitely be. Now, repeat that for the other mob. And….. done.
