The Game of Squares

Either boys or girls, usually aged from seven to ten, play the two-person game of"Mandarin's Box". They draw a rectangle on the ground and (1)……….. it into ten smallsquares called "rice fields" or "fish ponds”.

They also draw two additional semi-circular boxesat the two (2)………. of the rectangle, which are called"mandarin's boxes" - the game's name. Each person has 25 small pebbles and a bigger stone.

Each player places the stone in one of the mandarin's boxes and five small pebbles in each of the other squares. Then the game begins. The first player takes up the contents of one square on his or her side ofthe board, but not a mandarin's box and distributes the pebbles one by one, (3)……….. with the next square in (4)………. direction. Since each square contains five pebbles at the beginning, the first move will distribute five pebbles to the left or right.

After the last pebble is distributed, the player takes the contents of the following squareand repeats the distribution (5)………... But if the following square is one of the mandarin's boxes, the turn ends and passes to the other player.

If the last pebble falls into a square that precedes one empty square, the player wins all the contents of the square following the empty square and (6)……….these pebbles from the board. However, if there are two or more empty squares in a row, the player (7)…….. his or her turn.

Once a player has taken pebbles from the board, the turn is (8)……….to the other player. If all five squares on one player's side of the board are emptied at any time, that player must place one pebble he or she has aside back in each of the five squares so that the game can resume.

The game (9)………until the two mandarins' boxes have both been (10)……….. At the end of the game, the player with more pebbles wins, with each of the large stones counting as ten points.

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 from 28 to 34.

Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing.

Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of such unexplained behavior: Honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the sun’s position in the sky, and the speed of the dance tells how far the food source is from the hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could have inferred the location of the new site.

Other behaviors that may indicate some cognition include tool use. Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother chimpanzees occasionally show their young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food wells containing chocolate chips. Allowed to choose which pair they wanted, the chimpanzees almost always chose the one with the higher total, showing some sort of summing ability. Other chimpanzees have learned to use numerals to label quantities of items and do simple sums.

A. however

“But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could have infeưed the location of the new site.“ (Nhưng trong một nghiên cứu, khi các nhà thí nghiệm tiếp tục thay đổi địa điểm đặt thức ăn, mỗi lần di chuyển thức ăn cách xa hơn 25% so với địa điểm trước, những con ong mật săn mồi bắt đầu dự đoán nguồn thức ăn sẽ xuất hiện ở đâu tiếp theo. Khi các nhà nghiên cứu đến địa điểm mới, họ thấy những con ong vây quanh nơi đó, chở đợi thức ăn. Cho đến bây giở chưa ai giải thích được làm thế nào mà loài ong có bộ não với trọng lượng bốn phần mưởi nghìn của một ounce, có thể suy đoán được vị trí của địa điểm mới.)
