<span>My responsibility in this activity within the community is to develop a new community or a new type of neighborhood with new responsibilities and aptitudes. I can face problems and setbacks due to criticisms and complaints that do not bring benefit to the work, however, I can meet positive and optimistic people. As the plan unfolds there are several steps that arise from the initial idea and project guidelines, the construction contains an elaborate and detailed plan and a schedule of activities for each worker. In these guidelines are marked the possible solutions to different types of problems found throughout the work. Transportation, labor, materials and especially the budget. For this there is a list of problem solvency codes and norms and guidelines established for each situation. The citizens of this community will be satisfied with the result.</span>
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'.
