MCQ-> Analyse the following passage and provide appropriate answers for the questions that follow: Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected. The principal of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.” But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations – to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess. This imagining process is so difficult that there is a division of labour in physics: there are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess. We said that the laws of nature are approximate: that we first find the “wrong” ones, and then we find the “right” ones. Now, how can an experiment be “wrong”? First, in a trivial way: the apparatus can be faulty and you did not notice. But these things are easily fixed and checked back and forth. So without snatching at such minor things, how can the results of an experiment be wrong? Only by being inaccurate. For example, the mass of an object never seems to change; a spinning top has the same weight as a still one. So a “law” was invented: mass is constant, independent of speed. That “law” is now found to be incorrect. Mass is found is to increase with velocity, but appreciable increase requires velocities near that of light. A true law is: if an object moves with a speed of less than one hundred miles a second the mass is constant to within one part in a million. In some such approximate form this is a correct law. So in practice one might think that the new law makes no significant difference. Well, yes and no. For ordinary speeds we can certainly forget it and use the simple constant mass law as a good approximation. But for high speeds we are wrong, and the higher the speed, the wrong we are. Finally, and most interesting, philosophically we are completely wrong with the approximate law. Our entire picture of the world has to be altered even though the mass changes only by a little bit. This is a very peculiar thing about the philosophy, or the ideas, behind the laws. Even a very small effect sometimes requires profound changes to our ideas.Which of the following options is DEFINITLY NOT an approximation to the complete truth?

MCQ-> Read the given passage carefully and select the best answer to each question out of the four given alternatives.The Divine Comedy is a narrative poem describing Dante's imaginary journey. Midway on his journey through life Dante realizes he has taken the wrong path. The Roman poet Virgil searches for the lost Dante at the request of Beatrice; he finds Dante in the woods on the evening of Good Friday in the year 1300 and serves as a guide as Dante begins his religious pilgrimage to find God. To reach his goal, Dante passes through Hell, Purgatory and Paradise. The Divine Comedy was not titled as such by Dante; his title for the work was simply Commedia or Comedy. Dante’s use of the word "comedy" is medieval by definition. To Dante and his contemporaries, the term "comedy" meant a tale with a happy ending, not a funny story as the word has since come to mean. Dante and Virgil enter the wide gates of Hell and descend through the nine circles of Hell. In each circle they see sinners being punished for their sins on earth; Dante sees the torture as Divine justice. Dante first travels through circles of hell and then through 3 rings before entering the 8th circle. Then there are 9 bowge before Dante reached the 9th circle. After 9th circle Dante has to travel 4 more regions. On Easter Sunday, Dante emerges from Hell. Through his travels, he has found his way to God and is able, once more, to look upon the stars.To reach god, Dante has to pass through which of the following?
