According to the passage, a mother tongue

Directions: Answer the given question based on the following passage:

A survey of language, however superficial, makes it evident that when we speak of style, we have to take into account those qualities of national character which are embodied in national speech. If two men could be born of precisely the same physical, mental, and moral nature, at precisely the same moment of history, and under precisely the same social conditions; and if these men learned different languages in the cradle, and used those languages in after life, they would be unable to deliver exactly the same message to the world through literature. The dominant qualities of each mother-tongue would impose definite limitations on their power of expressing thoughts, however similar or identical those thoughts might be.
We cannot conceive two men born with the same physical, mental, and moral nature, at the same moment, under precisely the same conditions, and using the same language. They would be identical; and everything they uttered would be clothed with exactly the same words. The absurdity of this conception brings home to us the second aspect of style. Style is not merely a sign of those national qualities which are generic to established languages, and which constitute the genius of a race. It is also the sign of personal qualities, specific to individuals, which constitute the genius of a man.  Whatever a man utters from his heart and head is the index of his character. The more remarkable a person is, the more strongly he is differentiated from the average of human beings, the more salient will be the characteristic notes of his expression. But even the commonest people have, each of them, a specific style. The marks of difference become microscopical as we descend from Dante or Shakespeare to the drudges of the clerk’s desk in one of our great cities. Yet these marks exist, and are no less significant of individuality than the variations between leaf and leaf upon the lime-trees of an avenue.
It may be asked whether the manner of expression peculiar to any person is a complete index of his character—whether, in other words, there is ‘an art to find the mind’s construction’ in the style. Not altogether and exhaustively. Not all the actions and the utterances of an individual betray the secret of his personality. You may live with men and women through years, by day, by night, yet you will never know the whole about them. No human being knows the whole about himself.
The deliberate attitude adopted by a literary writer implies circumspection; invites suppression, reservation, selection; is compatible with affection, dissimulation, hypocrisy. So much cannot be claimed for critical analysis as for that we should pretend to reproduce a man’s soul after close examination of his work. What we may assert with confidence is that the qualities of style are intimately connected with the qualities and limitations of the writer, and teach us much about him. He wrote thus and thus, because this or this. In the exercise of style it is impossible for anyone to transcend his inborn and acquired faculties of ideation, imagination, sense-perception, verbal expression—just as it is impossible in the exercise of strength for an athlete to transcend the limits of his physical structure, powers of innervations, dexterity, and courage. The work of art produced by a writer is therefore, of necessity, complexioned and determined by the inborn and acquired faculties of the individual. This is what we mean by the hackneyed epigram: ‘Le style c’est l’homme. ’ This means ‘style is the man.’ (From Personal Style by JA Symonds)
