Read the following excerpt from a US court opinion:

was imposing a sentence that varied from the guidelines range based on its consideration of the § 3553(a) factors. It is not clear from the record whether the district court granted a six-level variance because it determined that a sentence of seventy-eight months was appropriate notwithstanding the guidelines range, or whether, instead, the district court would have granted a six level variance from the advisory guidelines range even if the guidelines range had been lower, i.e., if the position of trust enhancement had not been applied.

C. holding that although the guidelines should be the starting point and the initial benchmark of calculating a proper sentence the district court should then consider all of the  3553a factors to determine whether they support the sentence requested by a party
D. holding that plain error exists when 1 an error was committed 2 that was plain 3 that affected the defendants substantial rights and 4 the error seriously affects the fairness integrity or public reputation of judicial proceedings
E. recognizing under plain error review that the burden to show that substantial rights have been prejudiced is on the party that failed to raise the issue below and for an error to have affected substantial rights the error must have affected the outcome of the district court proceedings
