Directions: Read the following passage and answer the questions.
Anthropologists have placed together with the little they know about the history of left-handedness and right-handedness from indirect evidence. Though early men and women did not leave a written record, they did leave tool bones and pictures. Stone Age hand axes and hatches made from stone that was carefully chipped away made from sharp cutting edges. In some, the pattern of chipping shows that these tools and weapons were made by right-handed people, designed to fit comfortably into a right hand. Other Stone Age implements were made by or for the left-hander.
Prehistoric pictures, painted on walls of caves, provided further clues to the handedness of ancient people. A right-hander finds it easier to draw faces of people and animals facing towards the left whereas a left-hander finds it easier to draw faces towards the right. Both kinds of faces have been found in ancient paintings. On the whole, the evidence seems to indicate that prehistoric people were either ambidextrous or about equally likely to be left or right-handed. But in the Bronze Age, the picture changed. The tools and weapons found from that period are mostly made for right-handed use. The predominance of right-handedness among humans today had apparently already been established.
Which of the following developments occurred around the time of the Bronze Age?
Step-by-step Solution:
The correct answer is D. The prevalence of right-handedness.
The answer is found directly in the last few sentences of the passage, which describe the key change that occurred during the Bronze Age.
Conclusion: The only development that the passage specifically attributes to the Bronze Age is the clear shift towards a majority of right-handed people.
