Question Try to fill in the missing words: Mistake #1 One of the most important discoveries in medical history actually resulted from sloppy laboratory BLANK 1 of 28. A century ago, the average life expectancy was only around 50 years. Bacterial infections in cuts or burns were BLANK 2 of 28 80% of the time, and staggering numbers of people used to die from tuberculosis and pneumonia. In the year 1928, Sir Alexander Fleming, a Scottish researcher, was searching for a “wonder drug” that would be able to BLANK 3 of 28 all diseases. No one had managed to discover or BLANK 4 of 28 a chemical that would kill bacteria without harming the human body. One morning in September, Fleming, who was often described as BLANK 5 of 28 in the laboratory, returned from a family vacation. Before leaving, he had pushed a number of unwashed Petri dishes to the side of the bench so that a BLANK 6 of 28 could use the workspace while he was away. When Fleming got back, he was about to BLANK 7 of 28 the contaminated dishes when he noticed that a blue-green mold BLANK 8 of 28 in one of them had killed the bacteria around it. Fleming was then able to BLANK 9 of 28 the anti-bacterial substance from the mold and develop it for medicinal use – and that substance is known today as penicillin, the world’s most widely-used antibiotic. During World War II, penicillin saved countless lives and BLANK 10 of 28 the amputation of many limbs. By the time the war ended, U.S. companies were BLANK 11 of 28 650 billion units of penicillin a month. In the decades following this lucky discovery, life expectancy in BLANK 12 of 28 countries has shot up to around 80 years. Mistake #2 By the end of the year 1776, the American Revolutionary War was in full swing – but things were not going well for the nascent United States. The British had BLANK 13 of 28 New York City and pushed the revolutionaries southwest into New Jersey and Pennsylvania. Morale among the revolutionaries was low, BLANK 14 of 28 were limited, and the harsh winter weather didn’t help. George Washington, the commander-in-chief of the American army, planned a Christmas BLANK 15 of 28 on the British troops encamped in Trenton, New Jersey. Between December 25th and 26th, while the British soldiers were BLANK 16 of 28, Washington and his men crossed the Delaware River and marched towards Trenton. With the element of BLANK 17 of 28 on their side, Washington’s army won a decisive victory, capturing weapons, supplies, and about a thousand BLANK 18 of 28. However, this triumph was almost thwarted by a spy who actually observed Washington and his BLANK 19 of 28 near the river. He then sent a note to warn Colonel Johann Rall, BLANK 20 of 28 of the British troops at Trenton, of the impending attack. But the British soldiers were in a festive BLANK 21 of 28 due to the Christmas holiday, and Colonel Rall was playing poker (or, according to some versions of the story, BLANK 22 of 28) when he received the message. Engrossed in the game, he stuffed the note into his BLANK 23 of 28 pocket without reading it. Rall was later killed during the battle, with the unopened note still in his pocket. If the British had been BLANK 24 of 28 for the attack, Washington (who would later become the United States’ first president) as well as other key BLANK 25 of 28 could have been killed. The victory at Trenton, though relatively small in scale, was seen as a BLANK 26 of 28 point in the war because it boosted morale and increased enlistments in the revolutionary army. The United States eventually won the war and BLANK 27 of 28 independence from British control. If not for Colonel Rall’s poker (or chess) game, it’s possible that the United States would not exist as an independent BLANK 28 of 28 today.
