D:

Olean  > potter
Quarles > Potter
Nolen = Quarles > Potter

对，最后一行表明N>P(即由题中the Potter Company was started years after the Quarles Corporation. Nolen, Inc., and the Quarles Corporation were founded in the same year.推出P was started years after N)，不就说明N ....not as many as P吗？我的推论哪儿有问题？还是说E不如D直接和无懈可击？

first,  there is a jump between " start business" and " not been in business"  
in a inference question, we have to stay within the scope.

second,:  in E, " as many  as " is a comparison of equality.
