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 is the main idea of the passage? 

A. Wings are the most important physical attribute of birds

B. Different wing styles evolved for different types of flight

C. Birds have many specialized features that aid in their survival

D. Birds fly for many reasons

II.  Match the health problems with the correct advice.

1.   I have spots on my face.

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

C. Read the article quickly. Underline the places where the animals hide.

STRANGE SEA ANIMALS

Do you know that some animals are camouflaged? This means their color is the same as the colors around them. Some camouflaged animals hide in seaweed, rocks, and sand. Look at the photo on the left. This looks like seaweed, but it’s not! It’s the leafy seadragon. It hides in the seaweed. It's the same color as seaweed. Like the seaweed, its body is also in the shape of a leaf. Look at the photo below. This is a stonefish. It hides on the sand, near rocks. It looks like a rock. Where are its eyes and its mouth?

B. Read the title. Why do you think these animals are strange?
