46) Scientists at Johns Hopkins have discovered "striking" differences between men and women in a part of the brain linked with ability to estimate time, judge speed, visualize things three-dimensionally and solve mathematical problems.
47)The differences, the researchers say, may underlie well-known trends that vary by sex, such as the fact that more men than women are architects, mathematicians and race-car drivers.
In a study reported this week in the Journal Cerebral Cortex, the researchers show that a brain region called the inferior parietal lobule is significantly larger overall in men than in women. The area is part of the cerebral cortex and appears on both sides of the brain just above ear-level.
Also, there’s a symmetry difference, with men having a larger left IPL than right. 48) In women in the study, it’s the right IPL that’s somewhat larger, though the difference between the two sides of the brain

| Scientists discovered that atoms of
some substances are radioactive. This means that they are unstable and can be
split. The chain of splitting atoms releases great destructive energy and it was
this discovery which led scientists to develop the idea of an atomic bomb. The
American government secretly worked to produce such a bomb and the first version
was much more powerful than anyone had thought. By this time, the World War Ⅱ had ended in Europe. But the Japanese refused to surrender, the Americans decided that by dropping an atomic bomb on Japan, they could end the war quickly and save more of their soldier’s lives. Soon after midnight on 6 August 1945, a bomb was dropped on the city of Hiroshima, a civilian target. No warning was given and there was total devastation. Almost all the buildings were destroyed and more t A. was less powerful B. was dropped in Nagasaki C. was a failure D. was tested in desert 我来回答: 提交
