Câu hỏi: Read the following passage and blacken the letter A, B, C, or D on your answer sheet to indicate the correct answer to the following 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 2,000 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 physical differences between the two sides of the brain. The variation between the hemispheres corresponds to which side of the body is used to perform specific activities. Such studies, as well as studies of tool use, indicate that right- or left- sided dominance is not exclusive to modern Homo sapiens. Populations of Neanderthals, such as Homo erectus and Homo habilis, seem to have been predominantly right-handed, as we are.
The fact that the Inuit cut meat by holding it between their teeth is significant because______.
A. the relationship between handedness and scratches on fossil human teeth can be verified
B. it emphasizes the differences between contemporary humans and their ancestors
C. the scratch patterns produced by stone knives vary significantly from patterns produced by modern knives
D. it demonstrates that ancient humans were not skilled at using tools

Sự thật rằng người Inuit cắt thịt bằng cách giữ nó giữa hàm răng là rất quan trọng vì _____.
A. mối quan hệ giữa sự thuận tay và các vết trầy trên răng người hóa thạch có thể được xác định
B. nó nhấn mạnh sự khác biệt giữa người hiện đại và tổ tiên loài người
C. các kiểu vết xước do dao đá rất khác so với các kiểu do dao hiện đại gây ra
D. nó chứng minh rằng người cổ đại không giỏi dùng công cụ

(Người cổ đại được cho là đã cắt thịt thành các miếng bằng cách giữ chúng giữa hàm răng và cắt nó bằng dao đá, giống như người Inuit ngày nay. Đôi khi dao bị truột và để lại các vết xước trên răng. Các vết xước có chiều từ trái sang phải (ở những người thuận tay phải) phổ biến hơn những vết xước có chiều ngược lại (ở những người thuận tay trái).)
