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
答案他大脑中支配数学能力和空间推理能力的部分——这是构成爱固斯坦最擅长的那种思维的两个关键因素——比普通人的明显要大得多，而且其细胞间也许有着更多的相互联系，使得它们能够更加高效地共同发挥作用。
解析 这一长句由两个并列主谓句构成。在前一个分句中，that governs...reasoning是主语a portion of the brain的定语从句，破折号间的部分为对主语的补充说明，可看作主语的同位语：在第二个分句中，which后的部分是interconnections的非限制性定语从句。分析清楚句子结构后理解和翻译起来就较容易了。
