4 more free scrambled paragraphs: Kleist, Evolution, Arch, Machine Gun

Answers are below the exercise:

Like many Germans involved in efforts to kill Hitler, Mr. von Kleist was a soldier — a lieutenant in the German Army — but his family had long been active in the German resistance.

_____ (Q) When he asked his father for advice, “He got up from his chair, went to the window, looked out of the window for a moment, and then he turned and said: ‘Yes, you have to do that because a man who doesn’t take such a chance will never be happy again in his life.’ ” 

_____ (R) In January 1944, he was 22 and recuperating in Berlin from wounds he suffered in combat when he was approached by Col. Claus von Stauffenberg to join an assassination plot. 
_____ (S) At the time, Lieutenant von Kleist led a unit that was scheduled to meet with Hitler to show him new Army uniforms. 

_____ (T) Lieutenant von Kleist agreed to go through with the plan, but Hitler canceled at the last moment — he frequently changed his schedule late in the war — and Colonel von Stauffenberg and others began devising a new plan. 

_____ (U) Colonel von Stauffenberg asked Lieutenant von Kleist to take along hidden explosives, which he would then detonate at the meeting, killing Hitler and himself. 

When most of us think about evolution, we tend to think in terms of simple organisms evolving into more complex ones.

_____ (Q) It's no longer believed that humans are at the top of the evolutionary ladder, but evolution does tend to drive organisms towards greater complexity, does it not?

_____ (R) Greater complexity is sometimes a consequence of evolution, but simplification can also, therefore, be a winning strategy -- it all depends on the environment. 

_____ (S) Well, this is not always so. 

_____ (T) In fact, those organisms that leave the most offspring behind, simple or complex, seem to do best.

_____ (U) Simple chemical reactions evolved into simple cells, which later evolved into more complex organisms, and so on all the way up to humans.

After more than 2,000 years of architectural use, the arch continues to feature prominently in bridge designs and with good reason: its semicircular structure elegantly distributes compression through its entire form and diverts weight onto its two abutments, the components of the bridge that directly take on pressure.

_____ (Q) The natural curve of the arch and its ability to dissipate the force outward greatly reduces the effects of tension on the underside of the arch.

_____ (R) The greater the degree of curvature (the larger the semicircle of the arch), the greater the effects of tension on the underside of the bridge. 

_____ (S) Tensional force in arch bridges, on the other hand, is virtually negligible. 

_____ (T) But as with beams and trusses, even the mighty arch can't outrun physics forever. 

_____ (U) Build a big enough arch, and tension will eventually overtake the support structure's natural strength.

In 1881 the American inventor, Hiram Maxim, visited the Paris Electrical Exhibition and met a man who told him: "If you want to make a lot of money, invent something that will enable these Europeans to cut each other's throats with greater facility."

_____ (Q) Maxim used the energy of each bullet's recoil force to eject the spent cartridge and insert the next bullet.  

_____ (R) Trials showed that the machine-gun could fire 500 rounds per minute and therefore had the firepower of about 100 rifles. 

_____ (S) In 1885 he was able to demonstrate the world's first automatic portable machine-gun to the British Army. 

_____ (T) Maxim moved to London and over the next few years worked on producing an effective machine-gun.  

_____ (U) The Maxim Machine-Gun would therefore fire until the entire belt of bullets was used up.
