Why does the author use a problem-solution text structure in the paragraph?
Read the excerpt from Team Moon.
The trouble with option 2 was that the venting might push the fuel to an unstable condition. Or, another possible
outcome of the "burping": what if the landing gear hadn't deployed correctly? Could any movement, or any resulting burst—no matter how small-tip the LM over? Many a voice in the debate thought the safest option was
to abort—now! But that opinion was quickly overruled by the Grumman and NASA leadership (who were confident
of the landing gear), and the consensus of the leaders
was that it would be safe to gently, gently burp the
engine.

Read this passage: many manufacturers prefer plastic as a material for containers because it can be molded into many shapes. but plastic is not very strong. it must be fused with glass or steel for strength. it is also not very durable. even the strongest plastic can break under enough pressure. the biggest disadvantage to using plastic is that it does not decompose. while plastic can be recycled, doing so is tedious and difficult. while it may be more expensive and difficult to work with, aluminum is a much stronger building material with far greater tensile strength. it conducts electricity because it is metal. best of all, aluminum is very easy to recycle. even if it is thrown away, it decomposes much more quickly than most manufacturing materials. how does the compare-and-contrast organizational pattern of the passage support the author's purpose? a. the passage gradually leads up to the point about decomposition to inform the reader about the importance of recycling plastics. b. the passage lists the advantages and disadvantages of each material to make a case for the use of plastic and not aluminum in containers. c. the passage begins with a description of plastic's problems in order to call attention to the good qualities of aluminum. d. the passage shows the superiority of aluminum in order to make a case for the production of stronger plastics.
