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 following questions.
              Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles.
              To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows have short, broad wings. Faster birds, like hawks, have built-in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.
              Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops-an essential skill, since most birds need to land on individual branches or on prey.
              Flight takes muscle strength. If body builders has wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight.
              Birds carry no excess baggage; they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find prey, escape predators, and attract mates-in other words, to survive.
What does the author imply about the body builders having wings?
A.If they flapped their wings, they could fly a little.             
B.If they had wings, their muscles would be strong enough for flight.
C.If they had wings, their hearts would still not be large for flight.       
D.Their wings would total 15 percent of their body weight.

In most discussions of cultural diversity, attention has focused on visible, explicit aspects of culture, such language, dress, food, religion, music, and social rituals. Although they are important, these visible expressions of culture, which are taught deliberately and learned consciously, are only the tip of the iceberg or culture. Much of culture is taught and learned implicitly, or outside awareness. Thus, neither cultural insiders nor cultural outsiders are aware that certain "invisible" aspects of their culture exist.
Invisible elements of culture are important to us. For example, how long we can be late before being impolite, what topics we should avoid in a conversation, how we show interest or attention through listening behavior, what we consider beautiful or ugly. These are all aspects of culture that we learn and use without being aware of it. When we meet other people whose invisible cultural assumptions differ from those we have learned implicitly, we usually do not recognize their behavior as cultural in origin.
Differences in invisible culture can cause problems in cross-cultural relations. Conflicts may arise when we are unable to recognize others’ behavioral differences as cultural rather than personal. We tend to misinterpret other people's behavior, blame them, or judge their intentions or competence without realizing that we are experiencing cultural rather than individual differences.
Formal organizations and institutions, such as schools, hospitals, workplaces, governments, and the legal system are collection sites for invisible cultural differences. If the differences were more visible, we might have less misunderstanding. For example, if we met a man in a courthouse who was wearing exotic clothes, speaking a language other than ours, and carrying food that looked strange, we would not assume that we understood his thoughts and feelings or that he understood ours. Yet when such a man is dressed similarly to us, speaks our language, and does not differ from us in other obvious ways, we may fail to recognize the invisible cultural differences between us. As a result, mutual misunderstanding may arise.
The phrase "the tip of the iceberg" in bold in paragraph 1 means that ____.
 
A.other cultures seem cold to us
B.visible aspects of culture are learned in institutions
C.we usually focus on the highest forms of culture
D.most aspects of culture cannot be seen
