4.Left Handedness
What do Leonardo da Vinci,Marie Curie,and Albert Einstein have in common?They were all left-handed,along with other famous people including Barack Obama.In fact,an estimated 13percent of the world's population (25)may/canbe left-handed.
Most people are right-handed.This fact also seems to have held true (26)throughouthistory.In 1977,scientists studied works of art made at various times starting with cave drawings from 15,000B.C.and ending with paintings from the 1950s.Most of the people(27)shown/showed(show) in these works of art are right-handed.
Many researchers claim (28)to have found(find)relationships between left-handedness and various physical and mental characteristics.However(29)someof these connections are very weak,and others have not been proven.What makes a person become right-handed rather than left-handed?As yet,no one really knows for sure.(30)No matter whatreasons may be behind it,people's attitudes toward left-handedness have changed a lot over the years.There are even a number of shops(31)specializing(specialize) in selling products for left-handed people,such as left-handed scissors,can openers,guitars,and even a left-handed camera.In 1976,Left-Handers International,a group of left-handed people in Topeka,Kansas,in the United States,decided to start (32)anannual event in order to clear up misunderstandings about left-handedness.
