Answer:
The best paraphrase of this quotation from Abraham Lincoln's Gettysburg Address is A: We cannot do as much as the soldiers have done.
Step-by-step explanation:
What Abraham Lincoln is trying to say in this excerpt is that they, ordinary men, don't have the right to consecrate that ground because that job has already been done by the men who struggled there, who fight in that field, and he doesn't feel they have the right to do it over them. They were -some still are- courageous men that fought for all and they are nothing compared to them. This is how he feels about it and the reason why he thinks they have nothing to change because the memory of these men is stronger.
