The space shuttle and its rockets are huge – some 4, 5 million pounds at lift-off. About 85 per cent of that weight is fuel.Since it is designed to work in a vacuum, the shuttle must carry not only fuel but the oxygen to burn it.Because this is an inefficient way to go, NASA engineers have recently tested an engine that gets some of its oxygen on the run. This should reduce take off weights by half.A spacecraft equipped with this engine would take off like a rocket. But within minutes, incoming air would begin to supplement liquid oxygen. Once the spacecraft reaches a speed of 1,500 miles per hour – twice the speed of sound- the liquid oxygen would shut off completely and the engine would burn fuel mixed with air. Consequently the craft would accelerate to about ten times the speed of sound. When the air got too thin for the engine to breathe, the ship would shift back to rocket mode to punch its way into space.

96. According to the passage, a new rocket engine is presently being developed to _____.

A) reach previously unimagined speeds
B) make space travel more comfortable and feasible
C) halve the weight of a space shuttle at it-off
D) enable NASA to remain in the forefront of space exploration.
E) reduce the physical effects of the atmosphere on the shuttle

97. We learn from the passage that, in the usual space shuttle, the weight _____.

A) makes high speeds impossible
B) consists very largely of fuel
C) does not pose any serious problem
D) of the liquid oxygen is enormous
E) of the rockets is insignificant

98. As the passage points out, a space shuttle requires oxygen _____.

A) only when it is traveling within the atmosphere
B) if it is to attain very high speeds
C) but only in its liquid form
D) in order to burn the fuel
E) in quite small quantities except at lift-off

99. The point is made in the passage that the reason for developing the new engine is to _____.
A) reduce the time it takes the shuttle to exceed the speed of sound
B) double the speed at which the shuttle travels
C) economize on the use of liquid oxygen
D) eliminate the need for liquid oxygen and thus cut down on the shuttle’s weight
E) allow the shuttle to function in a vacuum

100. It is clear from the passage that, once there is not sufficient air to burn the fuel, then _____.
A) the speed of the shuttle increases to over ten times the speed of sound
B) the engine reverts back to using the liquid oxygen aboard the shuttle
C) the engine starts to increase the speed of the shuttle
D) it is impossible for the shuttle to accelerate any further
E) the rocket can no longer function efficiently

96 C) halve the weight of a space shuttle at it-off : This should reduce take off weights
by half

97 B) consists very largely of fuel : About 85 per cent of that weight is fuel

98 D) in order to burn the fuel : the shuttle must carry not only fuel but the oxygen to
burn it

99 D) eliminate the need for liquid oxygen and thus cut down on the shuttle’s weight :
Because this is an inefficient way to go, NASA engineers have recently tested an
engine that gets some of its oxygen on the run

100 D) it is impossible for the shuttle to accelerate any further : When the air got too thin
for the engine to breathe, the ship would shift back to rocket mode to punch its
way into space.

100.soruyu ben e yapmıstım :confused:

hava çok azaldığında roket moduna geçer ve daha fazla hızlanamaz diye düşündüm.çünkü roket modunda kalkışa geçiyor ve daha sonra hızlanıyor.ama emin değilim diğerleri kadar:)

the craft would accelerate to about ten times the speed of sound.bende burdan o sıkkı elemiştim cünkü kızı 10kat fazla oluyormus diye düşündüm

PS: Elde doğru olacak başka seçenek olmadığından bu seçenek istenen cevap olmalı. Yoksa seçeneğin doğru olamayacağını hep iddia edegelmişimdir: Sıvı oksijen ihtiyacı elimine edilmiyor. Daha az sıvı oksijen ihtiyacı duyan, ve bir kısım oksijenini havadan toplayan bir motordan bahsediliyor.

hocam bu cümleyi çevirebilir misiniz 100.sorunun cevabı burdan olsa gerek

hava, motorun alamayacağı kadar azaldığında , mekik roket moduna geçerek uzayda yolunu açar. evet burada cevap.

Başlığa gelmiş geçmiş en belalı KPDS sınavından bir reading sorusu demeye unutmuşum!

uzayda yolunu nasıl acıyor ki bi de 100.soruyu acıkalar mısnız ben hala anlamadım

punch : yumruklamak , delmek ... yol kelimesiyle bunlar gitmeyeceği için açmak dedim..yani ileri fırlar..

Başlığa gelmiş geçmiş en belalı KPDS sınavından bir reading sorusu demeye unutmuşum!

cevaplar ne peki hocam?

cevaplar ne peki hocam?

valla bilmiyorum hocam, ÖSYM de yayınlamadı zaten ama Mamger hocamın yanıtlarına güvenebilirsiniz.

rocket moduna geri döner diyor ama cevaptada sıvıyla ilgili bir şey diyor anlayamadım

rocket moduna geri döner diyor ama cevaptada sıvıyla ilgili bir şey diyor anlayamadım

roket moduna geçtiği zaman kullandığı sıvı oksijeni kullanmaya başlıyor.

When the air got too thin for the engine to breathe, the ship would shift back to rocket mode to punch its way into space.

burda gemi uzayda yolunu açmak için rocket moduna dönüyor ama 100.sorudaki cevapta motor sıvı kullanmaya geri dönüyor ben bu kısmı anlamadım iki tarafta çelişkili geldi yoksa yanlıs mı yorumluyorum onu acıklar mısınız aklım kaldı bu soruda simdi

Hava motorun soluyamayacağı kadar seyreldiğinde (mecaz yapmış, hani yukarı çıktıkça gaz azalır ve oksijen yüzdesi düşer ya: Artık oksijen yoğun -thick- değildir, thindir) uzay gemisi boşluğa doğru atılıp ilerlemek için yeniden roket moduna geçecektir (İlk kalkışta bir patlama ileri doğru hareketi sağlar ki bu roket modudur. Daha sonra bu parça atmosferden çıkarken boşluğa bırakılır. Gemide kalan az miktardaki yakıt sadece hızlanmak veya dönmek için falan kullanılacaktır: Malum uzay sürtünmesiz ve ilk hareket bir engelle karşılaşmadığı müddetçe aynı hız ve doğrultuda devam edecek. İşte bu "hızlanma" veya "doğrultu değiştirme" duurmunda uzay gemisi bir roket olarak işlev görecektir: Ateşleyicilerle ileri doğru fırlatılma.)

Umarım şimdi olmuştur.

PS: Bu arada ÖSYMnin en bela paragraf sorusu bu değil. :)

teşekkürler hocam
