Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Archaeological records, paintings, drawings, and carvings of humans engaged in activities involving the use of hands indicate that humans have been predominantly right-handed for more than 5,000 years. In ancient Egyptian artwork, for example, the right hand is depicted as the dominant one in about 90 percent of the examples. Fracture or wear patterns on tools also indicate that a majority of ancient people were right-handed.

Cro-Magnon cave paintings some 27,000 years old commonly show outlines of human hands made by placing one hand against the cave wall and applying paint with the other. Children today make similar outlines of their hands with crayons on paper. With few exceptions, left hands of Cro-Magnons are displayed on cave walls, indicating that the paintings were usually done by right-handers.

Anthropological evidence pushes the record of handedness in early human ancestors back to at least 1.4 million years ago. One important line of evidence comes from flaking patterns of stone cores used in toolmaking: implements flaked with a clockwise motion (indicating a right-handed toolmaker) can be distinguished from those flaked with a counter-clockwise rotation (indicating a left-handed toolmaker).

Even scratches found on fossil human teeth offer clues. Ancient humans are thought to have cut meat into strips by holding it between their teeth and slicing it with stone knives, as do the present-day Inuit. Occasionally, the knives slip and leave scratches on the users' teeth. Scratches made with a left-to-right stroke direction (by right-handers) are more common than scratches in the opposite direction (made by left-handers).

Still other evidence comes from cranial morphology: scientists think that physical differences between the right and left sides of the interior of the skull indicate subtle anatomical differences between the two sides of the brain. The variation between hemispheres corresponds to which side of the body is used to perform specific tasks. This evidence, as well as studies of tool use, indicates that right- or left-handedness extends far back in the history of Homo sapiens. Populations of earlier hominids such as Homo erectus and Homo habilis seem to have been predominantly right-handed as well.

Do you speak “elephant”?

As humans, we communicate using the senses of sight, touch, and hearing. We send messages with body language, we greet friends with touch and we speak using words to show our emotions and ideas. Animals don't communicate in as many ways as humans – for example, they don't have language like we do – but many animals do also use the senses of sight, touch, and hearing. A good example of this is elephant communication.

Like humans, elephants understand each other by looking at each other's body language. To send a message, they use their whole body, or individually their heads, eyes, mouth, ears, trunk, tail, or feet. For example, elephants spread their ears to show anger. And while humans shake their heads to disagree elephants do this to show they are happy.

As with humans, touch is also very important between elephants. Just like a human mother holds her baby, a mother elephant regularly touches her young calf with her trunk. Elephants also show they are friendly when they touch other elephants. And when they want to have fun, they hold each other by the trunk and pull, like in this photo. Even if they can’t laugh like a human, elephants have a great sense of humor.

Elephants have very large ears, which means they can hear other elephants from as far as 2.5 miles away. Like humans, they can also copy sounds and make their own sounds that seem to communicate basic human words and phrases like, “Hello,” “I love you,” and “Let's go.”

calf (n): a young elephant
