CSS English Chapter 4 Online Entry Test With Answers

Q-4. Both plants and animals of many sorts show remarkable changes in form,structure,growth habits,and even mode of reproduction in becoming adapted to different climatic environment,types of food supply,or mode of living.This divergence in response to evolution is commonly expressed by altering the form and function of some part or parts of the organism,the original identity of which is clearly discernible.For example,the creeping foot of the snail is seen in related marine pteropods to be modified into a flapping organ useful for swimming,and is changed into prehensile arms that bear suctorial disks in the squids and other cephalopods.The limbs of various mammals are modified according to several different modes of life-----for swift running (cursorial) as in the horse and antelope,for swinging in trees (arboreal) as in the monkeys,for digging (fossorial) as in the moles and gophers,for flying (volant) as in the bats,for swimming (aquatic) as in the sales,whales,and dolphins, and for other adaptations,the structures or organs that show main change in connection with this adaptive divergence are commonly identified readily as homologous,in spite of great alterations.Thus,the finger and wrist bones of a bat and whale,for instance,have virtually nothing in common except that they are definitely equivalent elements of the mammalian limb.

ii.The author provides information that would answer which of the following question?

I.What factors cause change in organisms?

II.What is the theory of evolution?

III.How are horses' legs related to seals'flippers?

Q-3. For me,scientific knowledge is divided into mathematical sciences,natural sciences dealing with the natural world (physical and biological sciences).and sciences dealing with mankind(psychology,sociology, all the sciences of cultural achievements,every kind of historical knowledge).Apart from these sciences is philosophy,about which we will talk shortly.In the first place,all this is pure or theoretical knowledge sought only for the purpose of understanding in order to fulfil the need to understand that is irtrinsic and comsubstantial to man.What distinguishes man from animal is that he knows and needs to know.If man did not know that the world existed,and that the world was of a certain kind,that he was in the world and that he himself was of a certain kind,he wouldn't be man.The technical aspects of applications of knowledge are equally necessary for man and are of the greatest importance,because they also contribute to defining him as man and permit him to a pursue a life increasingly more truly human.

But even while enjoying the results of technical progress,he must defend the primacy and autonomy of pure knowledge.Knowledge sought directly for its practical applications will have immediate and foreseeable success,but not the kind of important result whose revolutionary scope is in large part unforeseen,except by the imagination of the Utopians.Let me  recall well-known example.If the Greek mathematicians had not applied themselves to the investigation of conic sections,zealously and without the least suspicion that it might someday be useful it would not have been possible centuries later to navigate far from shore.The first men to study the nature of electricity could not imagine that their experiments,carried on because of mere intellectual curiosity,would eventually lead to modern electrical technology without which we can scarcely conceive of contemporary life.Pure knowledge is valuable for its own sake,because the human spirit cannot resign itself to ignorance but in addition it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.

iii.It can inferred from the passage that to the author man's need to know is chiefy important in that it?

Q-2.The history of mammals dates back at least to Triassic time.Development was retarded,however,until the sudden acceleration of evolutional change that occurred in the oldest Paleocene.This led in Eocene time to increase in average size,larger mental capacity,and special adaptations for different modes of life.In the Oligocene Epoch,there was further improvement,with appearance of some new lines and extinction of others.Miocene and Pliocene time was marked by culmination of several groups and continued approach toward modern characters.The peak of the career of mamals in variety and average large size was attained in the Miocene.

The adaptation of mammals to almost all possible modes of life parallels that of the reptiles in Mesozoic time,and except for greater intelligence,the mammals do not seem to have done much better than corresponding reptilian forms.The bat is doubtless a better flying animal than the pterosaur,but the dolphin horse and the antelope must excel any of the dinosaurs.The tyrannosaur was a more ponderous and powerful carnivore than any flesh-eating mammal,but the lion or tiger is probably a more efficient and dangerous beast of prey because of a superior brain.The significant point to observe is that different branches of the mammals gradually fitted themselves for all sorts of life,grazing on the plains and able to run swiftly (horse,deer,bison).living in rivers and swamps (hippopotamus,beaver),dwelling in trees (sloth,monkey) digging underground (mole,rodent),feeding on flesh in the forest (tiger) and on the plain (wolf),swimming in the sea (dolphin,whale,seal) and flying in the air (bat).Man is able by mechanical means to conquer the physical world and to adapt himself to almost any set of conditions.

This adaptation produces gradual changes of from and structure.It is biologically characteristic of the youthful,plastic stage of a group.Early in its career,an animal assemblage seems to possess capacity for change,which,as the unit becomes old and fixed disappears.The generalised types of organisms retain longest the ability to make adjustments when required,and it is from them that new,fecund stocks take origin - certianly not from any specialised end-products.So,in the mammals we witness the birth plastic spread in many directions,increasing specialisation,and in some branches,the extinction which we have learned from observation of the geologic record of life is a characteristic of the evolution of life.
