Lesson 3 The first detective story, written by Edgar Allan Poe and Author Conan Doyle, emerged in the mid 19th century, at a time when there was an enormous public interest in science. The newspapers of the day continually publicized the latest scientific discoveries, and scientists were acclaimed as the heroes of the age. Poe and Cohen Doyle share this fascination with the mythological, logical approach used by a scientist in their experiments, and instilled their detective heroes with outstanding powers of scientific reasoning. The main idea of the passage is
Science fiction was not popular among 19th-century readers

In computer design, the effectiveness of a program generally depends on the ability of the programmer. Still, remarkable progress has been made in the development of artificial intelligence. This process has scientists wondering whether it will eventually be possible to develop a computer capable of intelligent thought. When a computer defeated Garry Kasparov, considered by many the greatest chess player of all time, it was taken to be a vindication of the claims of the strongest supporters of artificial intelligence. Despite this accomplishment, others argue that while computers may imitate the human mind, they will never possess the capacity of true intelligence. The main idea of the passage is
computers can never learn to think
chess is a game in which computers are superior
great strides have been made an artificial intelligence
artificial intelligence is a scientific miracle
From the outset, the Titanic captured the public’s imagination. At the time, it was one of the largest and most opulent ships in the world. It was also considered unsinkable, due to a series of compartment doors that could be closed if the bow was breached. However, four days into its maiden voyage in 1912, the Titanic struck an iceberg, and less than three hours later it sank.

For do-it-yourself-types, the cost of getting regular oil changes seems unnecessary. After all, the steps are fairly easy as long as you are safe. First, make sure that the car is stationary and on a level surface. Always use the emergency break to ensure that the car does not roll on top of you. Next, locate the drain plug for the oil under the engine. Remember to place the oil drain pan under the plug before you start. When it is drained fully, wipe off the drain plug and the plug opening and then replace the drain plug. Next, simply place your final in the engine and pour in new oil.

After training the old oil from the engine, you should
replace the oil cap
run the engine for a moment and check the dipstick
wipe off and replace the drain plug
engage the emergency brake
A human body can survive without water for several days and without food for as many several weeks. If breathing stops for as little as 3 to 6 minutes, however, death is likely. All animals require a constant supply of oxygen to the body tissues, and especially to the heart or brain. In the human the body, the respiratory and circulatory systems perform this function by delivering oxygen to the body, which then transports it to tissues throughout the body. Respiration in large animals involves more than just breathing in the oxygen. It is a complex process that delivers oxygen while eliminating carbon dioxide produced by cells. Which bodily function, according to the passage is least essential to the immediate survival of the human being?
