In his preface to Spaceflight Revolution, David Ashford recalls how he started his research into rocket motors. As he later explains, these were motors that would power a space plane  one that would launch space travellers and satellites cheaply and reliably into orbit. That was 1961. Ashford admits he would probably have taken another job if he’d known that, 42 years later, satellites would still be launched by rockets descended from ballistic missiles. The technology is there, but political and budgetary decisions have so far stopped space planes getting off the ground. But Ashford presents a compelling argument that a small orbital space plane would cost relatively little to design and develop the equivalent of just two shuttle flights.

73. As we understand from the passage, Ashford’s space plane project ----.

A) has made space travel extremely cheap and reliable
B) has been welcomed by political authorities and received much attention
C) has received no political or financial support since the early 1960s
D) has been proved faulty in the course of several trials
E) was originally inspired by ballistic missile technology

74. According to the passage, Ashford ----.

A) has not yet completed his research into rocket motors
B) feels that his decades-long work on rocket motors has been unjustly ignored
C) has written his book Spaceflight Revolution mainly to criticize politicians
D) has been recognized as a leading scientist in space research and rocket technology for quite some time now
E) has proposed a project which can only be realized if a sizeable budget is available

75. As can be understood from the passage, Ashford is firmly convinced that ----.

A) the development of a space plane would cost no more than two shuttle flights
B) politicians and financial authorities need to be careful about investing money in space projects
C) rockets bear no relation to ballistic missiles
D) there are many people eager to be space travellers and willing and able to pay a reasonable fare
E) his work on rocket motors has greatly contributed to space research

76. It is clear from the passage that there ----.

A) is an ongoing debate on the uses of ballistic missiles
B) is some discrepancy between Ashford’s words and his actions isolation in preference to living in a crowded city
C) is much public support for Ashford’s project
D) are many technological differences between Ashford’s rocket motors and the conventional rockets currently in use
E) is much concern among space scientists, including Ashford, about the ever-growing costs of the space programme in general and of shuttle flights in particular

Except perhaps for some remote island dwellers, most people have a natural tendency to view continents as fundamental, permanent and even characteristic features of Earth. One easily forgets that the world’s continental platforms amount only to scattered and isolated masses on a planet that is largely covered by water. But when viewed from space, the correct picture of Earth becomes immediately clear. It is a blue planet. From this perspective it seems quite extraordinary that over its long history, Earth could manage to hold a small fraction of its surface always above the sea — enabling, among other things, human evolution to proceed on dry land. Is the persistence of highstanding continents just an accident? How did Earth’s complicated crust come into existence? Has it been there all the time, like some primeval icing on a planetary cake, or has it evolved through the ages? Such questions engendered debates that divided scientists for many decades, but the fascinating story of how the terrestrial surface came to take its present form is now partly resolved. That understanding shows, remarkably enough, that the conditions required to form the continents of Earth may be unmatched in the rest of the solar system.

69. One important point made in the passage is that ----.

A) new questions concerning the solar system are constantly coming to the fore
B) scientists have finally been able to understand fully the mystery of Earth’s crust
C) people living on remote islands are so cut off from the rest of the world that they have no idea about what is happening elsewhere
D) the formation of the continents of Earth may have no parallel elsewhere in the solar system
E) the growing pollution of the oceans is causing a great deal of concern among scientists

70. According to the passage, the question of how Earth’s continents came into being ----.

A) has never attracted much attention
B) has been one of the concerns of space research and exploration
C) can best be answered through a comprehensive study of the other planets in the solar system
D) is not likely to be resolved in the near future
E) gave rise to considerable disagreement among scientists

71. The passage calls Earth the “blue planet” to underline the fact that ----.

A) the waters of the oceans are crystal clear
B) the geographical features of Earth are not very distinct when viewed from space
C) many things on Earth are blue
D) there is actually very little land on Earth
E) it is man’s duty to keep the seas clean

72. The passage suggests that the inhabitants of small isolated islands ----.

A) will be adversely affected if the oceans continue to be polluted
B) have frequently chosen to live in comparative
isolation in preference to living in a crowded city
C) always demonstrate a keen interest in the solar system
D) depend for their living more on the sea than on the land
E) probably have a better perception of the reality of Earth than the majority of us

For almost 200 years, the idea of cosmic events affecting life on Earth was viewed as heretical by the church, which regarded catastrophe as proof of divine intervention, and as nonsense by the scientific establishment, which dismissed it as superstition. Yet in the end, the sheer weight of evidence has swept away all doubt about the reality of global catastrophes. Attempts to make scientific sense of the many legends of global catastrophes date back to the dawn of modern science itself, in the 17th century. Following the publication of Newton’s laws of motion and universal gravitation in 1687, Edmond Halley decided to apply them to the mystery of comets. By studying records of their appearance, Halley argued that the bright comets of 1456, 1531, 1607 and 1682 were in fact one comet, later known as the “Halley” comet, that followed a vast elliptical orbit around the Sun in agreement with Newton’s laws. But Halley noted something else as well: a comet crossing the orbit of the Earth might one day collide with us with devastating consequences.

65. According to the passage, Newton’s laws of motion and gravitation ----.

A) had no impact whatsoever on the rise of modern science
B) were approached skeptically by Halley and other contemporary scientists
C) helped Halley to identify the comet that bears his name
D) convinced Halley that catastrophes were in fact acts of divine intervention
E) were dismissed right away by the scientific establishment of his time

66. It is pointed out in the passage that, prior to the rise of modern science in the 17th century,----.

A) various studies had been made of comets, but Halley disregarded them all
B) the way people viewed cosmic events varied greatly
C) all kinds of learning had been subject to the approval of the church
D) the Earth had experienced several collisions with cosmic objects
E) attempts had been made to explain certain catastrophes with reference to gravitational laws

67. We learn from the passage that in the opinion of Halley, ----.

A) the mystery surrounding comets could never be cleared up
B) Newton’s laws of motion and gravitation needed to be further clarified and elaborated
C) the earlier appearances of the comet “Halley” had not been properly recorded
D) global catastrophes could be prevented through new scientific developments
E) a comet may, at some point in the future, strike Earth

68. It is clear from the passage that, in the past, the church ----.

A) regarded global catastrophes as acts of God
B) was particularly interested in the movements of comets
C) consistently banned any research into cosmic events
D) encouraged scientists to find ways of preventing global catastrophes
E) wished to suppress all thoughts of cosmic events

Henrik-Jan van Veen has carried out a great deal of research into spinning. This is especially true for “graveyard spins”, the term for what happens when fighter pilots get so disoriented they miscalculate how to get their plane back on course. They can end up in a dangerous and often fatal spin. Van Veen works at a research lab run by the Netherlands Organization for Applied Scientific Research, the TNO. The range of research covered by the TNO is vast, and it sees itself as a practical problem solver. And for the Dutch air force, the graveyard spin is certainly a problem that needs solving. Van Veen’s specialty is “vibrotactile devices”, which use vibrations to convey information. His latest project is a vest studded all over with small discs that can each vibrate independently. In a test room, a pilot is strapped into a seat in a “cockpit”. At the push of a button, the lights go out and the chair starts spinning. After a while the chair is stopped. “He’ll think he’s spinning the other way now”, says van Veen. The pilot is told to correct the spin, but instead, he overcorrects massively, and the chair begins spinning again. In the next test, the pilot dons van Veen’s vest and is told that the patch of the vest that is vibrating will indicate the direction he should force the joystick to correct a spin. This time, when the chair stops spinning the pilot manages to keep the seat still. Van Veen thinks the vibrotactile vest could do more than save the lives of fighter pilots. He’s now working on linking the system to a GPS receiver so that tourists in a foreign city or blind people in an unfamiliar environment can use the vest to find their way around.

61. It is clear from the passage that the vibrotactile vest ----.

A) has contributed significantly to environmental research
B) could be developed to serve a variety of purposes
C) has been in use in military aviation for many decades
D) is the product of an expensive research project undertaken by the Dutch military
E) could be used to transmit secret military information

62. It is understood from the passage that, because spins in fighter flights can be fatal, ----.

A) they are referred to as “graveyard spins”
B) van Veen has been testing a number of devices that could prevent spins
C) the TNO is making spin-prevention devices a major research project
D) many aircraft have been indefinitely grounded
E) all pilots are required to wear a vibrotactile vest

63. We understand from the passage that the Dutch research centre, the TNO, ----.

A) works in very close association with the Dutch armed forces
B) oversees all major research projects being carried out in the country
C) has put a lot of pressure on van Veen to extend the uses of vibrotactile devices
D) encourages the application of research for the solving of problems
E) puts safety devices high on its list of priorities

64. It is clear from the passage that van Veen’s immediate purpose in developing the vibrotactile vest is to ----.

A) help fighter pilots to calculate their course more accurately
B) warn pilots in advance that a spin is building up
C) help the blind find their way about
D) make it possible to reduce the amount of fuel used by aircraft
E) enable fighter pilots to get over the effects of aspin and thus, avoid a crash

How have terrestrial organisms met the environmental challenges of living on land? Life began in the oceans, but many life forms have since adapted to terrestrial life in a sea of air. Every single organism living on land has to meet the same environmental challenges: obtaining enough water; preventing excessive water loss; getting enough energy; and in polar regions, tolerating widely varying temperature extremes. How those challenges aremet varies from one organism to another, and in large part explains the diversity of life encountered on land today. Some animals avoid colder temperatures by migrating to warmer climates for the winter, whereas others avoid the cold by passing the winter in a dormant state called hibernation. Many plants also spend winter in a dormant state. The aerial parts of some plants die during the winter, but the underground parts remain alive; the following spring they resume metabolic activity and develop new aerial shoots. Many trees are deciduous; that is, they shed their leaves for the duration of their dormancy. Shedding leaves is actually an adaptation to the “dryness” of winter. Roots cannot absorb water from ground that is cold or frozen; by shedding its leaves the plant reduces water loss during the cold winter months when obtaining water from the soil is impossible.

57. It is pointed out in the passage that all terrestrial organisms ----.

A) in warm regions find it very hard to tolerate extreme temperatures
B) in polar regions live out the winter through hibernation
C) face the danger of extinction due to environmental challenges
D) have, one way or another, adapted themselves to environmental conditions
E) are most adversely affected by excessive water loss and cold temperatures

58. It is pointed out in the passage that the diversity of life on Earth ----.

A) is far more extensive in temperate climates than in colder ones
B) results from the variety of ways whereby organisms meet environmental challenges
C) is related to plants rather than other organisms
D) becomes far more apparent in spring than in winter
E) must be maintained through the conservation of the environment

59. One can understand from the passage that, for deciduous trees, the shedding of leaves ----.

A) increases the amount of water loss, which is a serious environmental challenge
B) increases their metabolic activity throughout winter
C) is an effective mechanism of resistance to heat
D) is a regular metabolic activity which is not related to environmental conditions
E) is a kind of hibernation that enables them to survive the cold winter months

60. It is clear from the passage that, for some animals, migration ----.

A) and hibernation are equally viable options
B) is comparatively easy
C) is indispensable for survival
D) causes a great deal of energy loss
E) involves various environmental challenges
