I think it's A but here's an explanation anyway: as you heat the crude oil, the different hydrocarbons, having different boiling points, boil and evaporate up the column. Those with lower boiling points, shorter in chain length, will condense nearer the top of the fractional distillation column. Those that are more viscous, larger in chain size, will have high boiling points, so will evaporate last and condense lower down in the column. Therefore, you achieve all the different oils / materials (oil, petrol, gasoline, tar etc etc). I hope this helps. If not, then a good website to use is 'BBC bitesize, fractional distillation'.
Some colonists became skilled craftsmen in the Middle Colonies because it ended up not being enough open farm land for everyone to farm and there was, at that time, not enough of other trades so instead of farming, they went to craftsmanship. Most of the farm land was also covered with a lot of forestry and at the time, tree removal was a very long and lengthy process; this meant that land would open up at a painfully slow pace. Basically, they didn't have much of an option to go to other avenues to make money.
Over the past two hundred years, the United States has played a important role in the economic and political activity of Haiti, its close neighbor to the south. The United States’ refusal to recognize Haiti as a country for sixty years, trade policies, military occupations, and role in Jean-Bertrand Aristide’s removal from Haiti are little known by Americans, but significant for the development, or rather, lack of development in Haiti. https://library.brown.edu/create/modernlatinamerica/chapters/chapter-14-the-united-states-and-latin-america/moments-in-u-s-latin-american-relations/a-history-of-united-states-policy-towards-haiti/
