Teks Explanation 11

A kite is an object which is made from a light material stretched over a frame. Due to its light material, a kite will lift off the ground and fly when it is tilted into the wind.

A kite uses wind to make it fly because it is heavier than air. When wind travels over the surface of the kite, it is split into two streams of air. One stream of the air goes over the kite while the second stream goes under the kite.

The upper stream above the kite. The lower stream hits the kite at a shallow angle and creates an area of high pressure.

The high pressure area has a pushing effect while the low pressure area has a pulling effect. The combination of push and pull can create enough force to lift the kite into the air.

Kites have been known for thousands of years. They are used for military or scientific purposes. Today's kites are much used for leisure and competition.

48. What is the function of the upper stream?

hits the kite at a shallow angle
creates an area of high pressure
creates an area of middle pressure
creates an area of low pressure
give space for kite to fly

Pembahasan

Kalimat "What is the function of the upper stream?" berarti "Apa fungsi aliran angin bagian atas?" Berdasarkan kalimat " The lower stream hits the kite at a shallow angle and creates an area of high pressure " berarti "Aliran angin yang lebih rendah menghantam layang-layang dengan sudut yang dangkal dan menciptakan area bertekanan tinggi", maka secara implisit dapat disimpulkan bahwa angin bagian atasmenciptakan area bertekanan rendah (creates an area of low pressure). Jadi, jawaban yang benar adalah D.
