I'm taking a test and have to guess the right answer to the question after the article. Article: Knots are the kind of stuff that even myths are made of.In the Greek legend of the Gordian knot, for example, Alexander the Great used his sword to slice through a knot that had failed all previous attempts to unite it. Knots, enjoy a long history of tales and fanciful names such as "Englishman's tie, " "and "cat's paw. " Knots became the subject of serious scientific investigation when in the 1860s the English physicist William Thomson (known today as Lord Kelvin) proposed that atoms were in fact knotted tubes of ether . In order to be able to develop the equivalent of a periodic table of the elements, Thomson had to be able to classify knots -- find out which different knots were possible. This sparked a great interest in the mathematical theory of knots. A mathematical knot looks very much like a familiar knot in a string, only with the string's ends joined. In Thomson's theory, knots could, in principle at least, model atoms of increasing complexity, such as the hydrogen, carbon, and oxygen atoms, respectively. For knots to be truly useful in a mathematical theory, however, mathematicians searched for some precise way of proving that what appeared to be different knots were really different -- the couldn't be transformed one into the other by some simple manipulation . Towards the end of the nineteenth century, the Scottish mathematician Peter Guthrie Tait and the University of Nebraska professor Charles Newton Little published complete tables of knots with up to ten crossings. Unfortunately, by the time that this heroic effort was completed, Kelvin's theory had already been totally discarded as a model for atomic structure. Nevertheless, even without any other application in sight, the mathematical interest in knot theory continued at _ point for its own sake. In fact, mathematical became even more fascinated by knots. The only difference was that, as the British mathematician Sir Michael Atiyah has put it, "the study of knots became a special branch of pure mathematics. " Two major breakthroughs in knot... Question: According to the passage, _ shows the most updated study about knots. Options: A: t 2-t+1 B: t 2-3t+1 C: Alexander polynomial D: Jones polynomial

I'm taking a test and have to guess the right answer to the question after the article. Article: For three days Mr Bunter did not say a word. He looked at people sensibly enough but seemed unable to hear any questions put to him. An officer remarked to the captain, "Those brass plates on the steps of the bridge-ladder are very dangerous things. " "Are they?" replied Captain Johns, "It takes more than a brass plate to make an able-bodied man fall down in that way. And the weather fine, everything dry, and the ship going on a smooth sea!" On the fourth day, the chief officer looked better. He could hear and understand and could even speak in a weak voice. "Well, Mr Bunter," said Captain Johns, "Can you tell us what caused the accident!" Bunter moved his head slightly and fixed his cold blue stare on the Captain's eyes and said in a whisper, "You--were--right!" "Bless my soul!" cried out Captain Johns, "Do you mean you had a supernatural experience that night? You saw a ghost on my ship?" Unwillingness, shame, disgust would have been seen on poor Bunter's face if a good part of it had not been wrapped in bandage . He tried hard and answered, "Yes, I have seen." "And did it --did it knock you down from the ladder?" "Come! Am I the sort of man to be knocked down by a ghost?" Captain Johns pointed a finger at Bunter. "You've been terrified, " he said , "That's what's the matter, even the man at the wheel was frightened, though he couldn't see anything. He felt the supernatural. You've been punished because you wouldn't believe, Mr Bunter. " "Suppose I have, " said Bunter, "You don't know what I saw. And I can't tell you what it was like. Every man has his own ghosts. I stepped back. I don't remember anything else. " "The man at the wheel said you went backwards as if something had hit you." "It was a sort of inward blow, " Bunter explained, "Aren't you satisfied now that I believe?" Question: We can know from the story that _ . Options: A: Mr Bunter had been punished because of his disbelief in ghost B: the ghost had hit Mr Bunter and he had fallen backwards C: Mr Bunter had somehow fallen down the bridge backwards D: Mr Bunter had hit himself against the brass plates on the steps of the bridge ladder
