根据下列文章,请回答题。Text 2Everyone of us lives and works on a small part of the earth's surface, moves in a small circle,and of these acquaintances knows only a few intimately. Of any public event that has wide effects we see at best only a phase and an aspect. This is true that the eminent insiders, who draft treaties,make laws, and issue orders, are like those who have treaties framed on them, laws promulgated to them, orders given at them. Inevitably our opinions cover a bigger space, a longer reach of time,many things, that we can directly observe. So they have to be pieced together out of what others have reported and what we can imagine. Yet even the eyewitness does not bring back a naive picture of the scene. For experience seems to show that he himself brings something to the scene which later he takes away from it, that oftener than not what he imagines to be the account of an event is really a transfiguration of it. Few facts in consciousness seem to be merely given. Most facts in consciousness seem to be partly made. A report is the joint product of the knower and known,in which the role of the observer is always selective and usually creative. The facts we see depend on where we are placed, and the habits of our eyes.The limited time and space which man occupies suggest, according to the paragraph,_____ A．man's life is also insignifican
B．man's opinions can not be accurate at al
C．human observations in general are all but partia
