问题       It doesn’t take an Einstein to recognize that Albert Einstein’s brain was very different from yours and mine The gray matter housed inside that shaggy head managed to revolutionize our concepts of time, space, motion — the very foundations of physical reality — not just once but several times during his astonishing career. 61)Yet while there clearly had to be something remarkable about Einstein’s brain, the pathologist who removed it from the great physicist’s skull after his death reported that the organ was.to all appearances, well within the normal range — no bigger or heavier than anyone else’s.
     But a new analysis of Einstein’s brain by Canadian scientists, reported in the current Lancet, reveals that it has some distinctive physical characteristics after all. 62)<>A portion of the brain that governs mathematical ability and spatial reasoning—two key ingredients to the sort of thinking Einstein did best — was significantly larger than average and may also have had more interconnections among its ceils, which could have allowed them to work together more effectively.<>
     In 1996,Harvey gave much of his data and a significant fraction of the tissue itself to Dr Sandra Witel-son, a neuroscientist who maintains a "brain bank" at McMaster for comparative studies of brain structure and function. 63)These normal, undiseased brains, willed to science by people whose intelligence had been carefully measured before death, gave Witelson a solid set of benchmarks against which to measure the seat of Einstein’s brilliant thoughts.
     Not only was Einstein’s inferior parietal region unusually bulky, the scientists found, but a feature called the Sylvian fissure was much smaller than average, 64)Without this groove that normally slices through the tissue, the brain cells were pecked close together, permitting more interconnections—which in principle can  permit more cross-referencing of information and ideas, leading to great leaps of insight.
     That’s the idea, anyway. But while it’s quite plausible according to current neurological theory, that doesn’t necessarily make it true. We know Einstein was a genius, end we now know that his brain was physically different from the average. But none of this proves a cause-and-effect relationship. "What you really need, "says McLean’s Benes," is to look at the brains of a number of mathematical geniuses to see if the same abnormalities are present."
     Even if they are, it’s possible that the bulked-brains are a result of strenuous mental exercise, not an inherent feature that makes genius possible. 65)Bottom line: we still don’t know whether Einstein was born with an extraordinary mind or whether he earned it, one brilliant idea at a time.
选项
答案事实是：我们仍不知道爱因斯坦是生来就拥有非凡的头脑呢，还是后天获得的，使他能够不时她产生出非凡的思想?
解析 本题句子结构较简单，冒号后的部分相当于一个表语从句，即Bottom line is...。其中含有由whether ...or...引导的两个宾语从句，而逗号后的部分是后一个宾语从句的方式状语。考生要注意的主要是词汇的翻译。bottom line指的是“(不得不接受的)事实或现实”，be born with指“生而拥有”，at a time指“每次”。
