Text 3 This line of inquiry did not begin until earlier this month--more than three months after the accident--because there were "too many emotions, too many egos," said retired Adm. Harold Gehman, chairman of the Columbia Accident Investigation Board. Testifying before the Senate Commerce Committee, Gehman said this part of his inquiry Was in its earliest stages, starting just 10 days ago. But Gehman said he already has concluded it is "inconceivable" that NASA would have been unable or unwilling to attempt a rescue for astronaut, s in orbit if senior shuttle managers and administrators had known there was fatal damage to Columbia’s left wing. Gehman told reporters after the hearing that answers to these important questions could have enormous impact, since they could place in a different context NASA’s decisions against more aggressively checking possible wing damage in the days before Columbia’s fatal return. Investigators believe breakaway insulating foam damaged part of Columbia’s wing Shortly after liftoff, allowing superheated air to penetrate the wing during its fiery re-entry on Feb. 1 and melt it from the inside. Among those decisions was the choice by NASA’s senior shuttle managers and administrators to reject offers of satellite images of possible damage to Columbia’s left wing before the accident. The subject dominated the early part of Wednesday’s hearing. Gehman complained that managers and administrators "missed signals" when they rejected those offers for images, a pointedly harsh assessment of the space agency’s inaction during the 16 day shuttle mission. "We will attempt to pin this issue down in our report, but there were a number of bureaucratic and administrative missed signals here," Gehman told senators. "We’re not quite so happy with the process." The investigative board already had recommended that NASA push for better coordination between the space agency and military offices in charge of satellites and telescopes. The U. S. National Imagery and Mapping Agency in March agreed to regularly capture detailed satellite images of space shuttles in orbit. Still, Gehman said it was unclear whether even images from America’s most sophisticated spy satellites might have detected on Columbia’s wing any damage, which Gehman said could have been as small as two inches square. The precise capabilities of such satellites was a sensitive topic during the Senate hearing. What does the word "they" (Para.’3, Line 2) refer to

Part ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on Answer Sheet 1.Text 1 When young people who want to be journalists ask me what subject they should study after leaving school, I tell them: "Anything except journalism or media studies." Most veterans of my trade would say the same. It is practical advice. For obvious reasons, newspaper editors like to employ people who can bring something other than a knowledge of the media to the party that we call our work. On The Daily Telegraph, for example, the editor of London Spy is a theologian by academic training. The obituaries editor is a philosopher. The editor of our student magazine, Juice, studied physics. As for myself, I read history, ancient and modern, at the taxpayer’s expense. I am not sure what Charles Clarke, the Education Secretary, would make of all this. If I understand him correctly, he would think that the public money spent on teaching this huge range of disciplines to the staff of The Daily Telegraph was pretty much wasted. The only academic course of which he would wholeheartedly approve in the list above would be physics -but then again, he would probably think it a terrible waste that Simon Hogg chose to edit Juice instead of designing aeroplanes or building nuclear reactors. By that, he seems to mean that everything taught at the public expense should have a direct, practical application that will benefit society and the economy. It is extremely alarming that the man in charge of Britain’s education system should think in this narrow-minded, half-witted way. The truth, of course, is that all academic disciplines benefit society and the economy, whether in a direct and obvious way or not. They teach students to think--to process information and to distinguish between what is important and unimportant, true and untrue. Above all, a country in which academic research and intelligent ideas are allowed to flourish is clearly a much more interesting, stimulating and enjoyable place than one without "ornaments", in which money and usefulness are all that count. Mr. Clarke certainly has a point when he says that much of what is taught in Britain’s universities is useless. But it is useless for a far more serious reason than that it lacks any obvious economic utility. As the extraordinarily high drop-out rate testifies, it is useless because it fails the first test of university teaching---that it should stimulate the interest of those being taught. When students themselves think that their courses are a waste of time and money, then a waste they are. The answer is not to cut off state funding for the humanities. It is to offer short, no nonsense vocational courses to those who want to learn a trade, and reserve university places for those who want to pursue an academic discipline. By this means, a great deal of wasted money could be saved and all students the academic and the no, so-academic--would benefit. What Mr. Clarke Seems to be proposing instead is an act of cultural vandalism that would rob Britain of all claim to be called a civilised country. The second paragraph is meant to demonstrate that ______.
