Read the following passage carefullys
⠀ In laying submarine cables it has been necessary. to probe the depths, and this has led to the exploration of the sea-bottom. To decide how and where it is best to lay a new cable demande some knowledge of what the bottom of the sea is like,
) Explorare distinguish between the terrigenous 2016 of the ocean and the pelagic or deep sea-area.
- The terrigenous zone is where the sea washes the) earth away and the rivera bring down the scattered broken pieces of the land. The floor of this zone is spread with earthy products, – shells, and chalky infusoria. Through clear water may be seen rests of coral, fish of all colours, and submarine forests, where strange creatures creep. The terrigenous sone sometimes extends two or three: hundred miles to seansud,
The deep sea-bottom is very different. Here the ordinary depth varies from two to five miles, In these solitudes there is no light except what may cone from the electrical bodies of some of the fish,! Beyond a certain depth scarcely anything solid will/ sink, so great is the pressure of water overhead. It is believed that in the lowest depths even a founderad ship dose not touch the botton, and that' Bose of the electric cables remain suspended through the water, never touching the floor. It is. certain that in shallower places they are hung in chains from oliff to cliff of the wide submarine valleys,
Yat something definite is known of the deep {ssa-bottom, It was discovered by Her Majesty's ship,
The Challenger, that over the pelagis area of the ocean stretobes an immense carpet of red mud. Ita colour is found to be rod when it is pulled up. At the deep sea-botton, whore there is no light, it must look black.
This redness is dua to oxides of iron, manganese nickel, and other metals. There is no chalk, nor any of the shell siftinge common to shallower depths
Mixed with the red clay are found those relics of whale and shark, which the salt water has not been able to melts such as the black, hard, fossil teeth. of sharks, and the ear-bones of whales. The Challenger, in only one haul of the dredge, brought up 600 sharka! teeth and 100 ear-bones of whales.
The red mud which covers these inaccessible solitudes does not come up anywhere on the visibls globe to show itself among the sedimentary rocke
It Is older then the hills, and largely made from the light porous stone and volcanic materials constantly being ajected by huga fumaroles and hidden craters through the sé-bottom.
It is into thie black, unapproachable wilderness that we drop our oablar, through whicoh messages are flashed almost at lightning speed from one side of the globe to another,he North Atlantio ia crossed at this moment by no fewer than fourteen cables, all of which are used day and night for sending messages between America and Europe. The breakages of cable occur mainly, not in the deep-sea, where the cable is. beyond reach of injury, but where it skirts a shallow coast-line or encounters the changing currents of rivers and estuaries.

Read the following passage carefully
Although the Greeks had inherited from Eastern civilizations some knowledge of the stars, metals, plants, and other things, such knowledge was haphazard. It enabled men to cope with specifio. situations but gave no general insight into the nature of the world. For instance, Egyptian builders knew that when a atring was knotted into 12 equal lengths and tautened to make a triangle with sides of three, four, and five lengths, the triangle was right-angled. But it took a Greek, Pythagoras to prove the general theorem about right-angled triangles, The notion of proof, of general demonstration, is a peculiarly Greek invention. It is what marks the beginnings of science and philosophy, as against the vague gropinge of earlier ages.
Moreover, the Greek thinkers were unique in that they undertook their inquiries not primarily for practical advantage, They sought to understand the world for the sake of inquiry itself. Our own philosophic tradition goue baok directly to thesä thinkers that is why Greek philosophy is still important today. To understand how the great questions of philosophy and science have arisen we must study their Greek origins
The first of early philosopher-scientists were from Miletus, the Ionian trade canter on the coast or the Aegean. They tried to give a general account of the world, of how it is made, and how it changes. Thales (about 640-546 B.0.), the founder of the Milesian school, is remembered chiefly for his statement that all things are made of water. This
early form of materialien (the belief that all things are made of the same basic stuff) is not just guesswork. It is easy to observe that: from the Burface of the sea the sun sucks up water by evaporation which later comes down as rain. From facts such as these the scientist jumpa to general conclusions, or hypothases, such as that all things. are made of water. That this visw has since been found false, is unimportant here, indeed it is almost an advantages since the content of these theories han now no further scientific interest, it is all the easier to study the form of the arguments. Our concern is the method used to formulate the materialist

Heraclitus of Ephesus, who flourished about 500 B.C., was not particularly interested in: scientifié parauits. But starting from the theory of strife put forward by Thales' successor Anaximander, and from Pythagoras' notion of harmony, he produced a new theory to show what makes the world go on) why, that is, it does not succumb to strife and chace. ansver 18 that the numerous and continual changed in. the world kappen according to set measures, or proportions. This is what Hersolitus means by sayings)
Strife is the father of all." Everything constantly changes so that when you step into the same river - twice, the second time the water will be different and therefore the river not quite the name. For A Heraclitus, the basic stuff is fire; the flickering of a flame and the material changes in the process combustion symbolize the theory that everything is, always in * #tate of flux.
