    Q1:

    Nitro glycerine could explode with even a small ________

     

    The first of these crates arrived in a postal centre in San Francisco, and upon being accidentally dropped, promptly exploded, killing all 15 people present. The point was taken. 'Nitro' was dangerously shock sensitive.

    Note:

    • After scanning, we can quickly find the needed information of Q1 should be found in paragraph B by the keywords “Nitro glycerine” and explode”.

    • The writer states that Nitro was easily damaged by shock (shock sensitive).  For that reason, the answer is “Shock”.

  • 2 Answer: death toll
  • Keywords in Questions

    Similar words in Passage

    Q2

    thus it was the cause of a growing ________

    The problem was then in thawing it back into liquid from, at which point it became even more unstable. Again, a mounting death toll would testify to this fact.

    Note

    • The keywords of Q2 are "cause", “growing”.

    • According to second paragraph, it (Nitroglycerin) became more unstable after throwing it back into water. As a result, this fact leads to a mount ting death toll.

    • For that reason, the answer is “death toll”.

  • 3 Answer: shatter rock
  • Keywords in Questions

    Similar words in Passage

    Q3:

    It was able to________ since, in contrast to gunpowder

     Gunpowder could not efficiently shatter rock (although it was suitable for bullets and artillery shells). Only nitro could really do the job, and a Swedish chemist, Alfred Nobel, became interested.

    Note

    • The keywords of Q3 are "able”, “gunpowder”.

    • According to paragraph 3rd, rock could not be shattered (broke) by gunpowder and only nitro could able to do this job (shatter rock).

    • All thing considered, we can conclude that the answer must be “shatter rock”.

  • 4 Answer: detonates(ed)
  • Keywords in Questions

    Similar words in Passage

    Q4:

    it ________, nitro could be handled more safely, yet deaths continued.

    Nitro is a 'high' explosive, meaning that it 'detonates' - that is, is triggered to react by the virtually instantaneous shock wave, producing gases which expand at more than the speed of sound.

    Note

    • The keywords of Q4 are " Nitro”, “2004”, “museum”.

    • Following the previous question (Q3), Nitro could be able to shatter rock by it “detonates” – this means that nitro is triggered to react by shock wave to explode.

    • All thing considered, we can conclude that the answer must be “detonates”.

  • 5 Answer: frozen
  • Keywords in Questions

    Similar words in Passage

    Q5: When ______, nitro could be handled more safely, yet deaths continued.

    However, it was soon discovered that when frozen (at about five degrees), nitro was much less sensitive to shock.

    Note:

    • The keywords of Q5 are " Nitro”, “handled more safely” and “when”.

    • “much less sensitive” can be inferred as less dangerous, or “more safely”. When you handle anything, there is a shock against that object. So when things are less sensitive to shock, it means that they can be handled more safely.

    • According to the passage, nitro can be handled more safely when it is frozen at about 5 degrees. Since only a maximum of two words is allowed, the most suitable answer is “frozen”.

Questions 10-13

Section 1

Reading Passage 1

You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage One.

It’s Dynamite

In 1866, an American railroad company was constructing a tunnel through the Sierra Nevada mountains. They encountered particularly hard rock, and ordered three crates of the only blasting explosive that could do the job: nitroglycerine. The first of these crates arrived in a postal centre in San Francisco, and upon being accidentally dropped, promptly exploded, killing all 15 people present. The point was taken. 'Nitro' was dangerously shock sensitive. Its transportation was soon banned, and from then on, it had to be manufactured by on-site laboratories - an expensive and still quite dangerous task, as the number of deadly explosions would demonstrate.

The history of nitroglycerine is full of such sad events. It was first synthesised in 1847 by Ascanio Sobrero, an Italian chemist, and he was so frightened by his discovery that he did not immediately publish his findings. He was also the first to caution the world against its use, in both private letters and a journal article, arguing that it was impossible to handle the substance safely. However, it was soon discovered that when frozen (at about five degrees), nitro was much less sensitive to shock. The problem was then in thawing it back into liquid from, at which point it became even more unstable. Again, a mounting death toll would testify to this fact.

Yet nitroglycerine always remained in demand, being the first practical mining explosive produced. Prior to this, gunpowder was used, but this was limited and clumsy. Gupowder is a 'low' explosive, meaning that it 'burns' from layer to layer, producing gases which expand at less than the speed of sound. Nitro is a 'high' explosive, meaning that it 'detonates' - that is, is triggered to react by the virtually instrantancous shock wave, producing gases which expand at more than the speed of sound. Gunpowder could not efficiently shatter rock (although it was suitable for bullets and artillery shells). Only nitro could really do the job, and a Swedish chemist, Alfred Nobel, became interested.

Nobel's companies were moving from primarily iron and steel production to the almost exclusive manufacture of cannons, armaments, and gunpowder, and he saw the commercial value in making nitroglycerine manageable. He began experimenting - at considerable cost. In 1864, his younger brother and several workers were killed in a factory explosion. Undererred, Nobel built a new factory in the remote hills of Germany, determined to find the answer. He first tried combining nitro with conventional gunpowder, marketing the final product as 'blasting oil', yet accidental explosions continued. His factory was destroyed yet again, on two occasions!

The breakthrough finally came when Nobel's company mixed liquid nitroglycerine with an inert absorbent silicate sand, known as 'diatomaccous earth'. This was produced by grinding down diatomite, a rock found around the local hills. It is similar to volcanic pumice, being very light and highly porous, yet it is actually the fossilised remains of diatoms, a hard-shelled alga. This combination immediately made nitro less dangerous to handle, and by being solid, more convenient to package and transport. Nobel patented his invention in 1867 under the name of 'dynamite', based on 'dyna' the Greek word for 'power'.

In its best-known form, dynamite was made in short paper-wrapped sticks consisting of three quarters intro to one quarter diatomaccous earth, but it would always remain dangerous to manufacture, store, and use. Over time, the nitro can seep out, crystallising on the outside of the sticks or pooling at the bottom of storage boxes, with all the consequent instability that raw nitro possesses. Nevertheless, in an age of extensive railroad and tunnel construction, the product would earn Nobel a great fortune. Yet, while high explosives serve a commendable purpose in peacetime engineering projects, Nobel's fortune was also based on weapons of death and destruction, and the public knew it.

Nobel himself was to become greatly perturbed, especially given the events which occurred when his brother Ludvig died. The French newspapers mistakenly thought it was the death of Alfred himself, and published an obituary. Alfred happened to be in France at the time, and one can only wonder at his reaction upon reading about his own death! Yet the obituary was harsh and condemning, calling Nobel the 'merchant of death', someone who 'became rich by finding ways to kill more people faster than ever before'. It was certainly this event which influenced him, in 1895, to write a new last will and testament, one year before he died. It would astonish everyone, and change the course of history.

When Alfred Nobel died, single and childless, at age 63, he specified that, apart from some minor bequests, his vast fortune (about 200 million dollars in today's money) be set aside for the establishment of the Nobel Prizes. These would be awarded annually for those who confer the 'greatest benefit on mankind' in physics, chemistry, peace, medicine, and literature. Nobel's strategy worked, as the Nobel Prizes are now considered among the most prestigious in the world. Few consider that all that money comes from nitroglycerine, dynamite, gunpowder, and armament manufacture, the indirect cause of incalculable human carnage.
