Q: The mystery stories of Sir Arthur Conan Doyle are famous all over the world. The detective in his stories is called Sherlock Holmes. He solves mysteries in a most surprising way. His assistant, Dr Watson, watches with admiration and then writes up the story of the mystery afterwards. This is a useful story writing skill. Because Watson is not very clever, the story remains a mystery until the end. The readers can sometimes pick up some clues before he does! Then, to make Watson understand the mystery, Holmes has to explain it all, step by step. So we, the readers, get to see it step by step too. Watson is almost as good a character in the story as Sherlock Holmes! The very first time they meet, Holmes greatly surprises Watson. When they are first introduced, Holmes says to Watson, 'How do you do? I see you have been to Afghanistan .' Watson is too amazed by this to ask Holmes how he knows this. Watson has, indeed, been to Afghanistan. Later, he asks Holmes about it. Holmes explains that there is nothing magical about what he does. He gets to know it all by very, very careful observation . Observation One Watson was introduced to Holmes as a doctor. Yet Holmes thought that the way he stood and walked made him seem like a soldier. So, this meant he was probably an army doctor. Observation Two Watson's face was quite dark skinned. But his wrists were pale. So his dark face was probably sun burnt. This meant that he had been to a hot, sunny country. Observation Three At the time, the British army had soldiers at bases in many parts of the world. So there were still a lot of places to choose from. However, Holmes saw that Watson looked very tired and he was always holding his left arm, as if it was painful. So, he had probably been with the army to a place where they were fighting. There was only one place where the British army was fighting at that time: Afghanistan.

input: Make use of the article to answer the questions. 16:9 (1.7:1) (16:9 = 4:3) is an aspect ratio with a width of 16 units and height of 9. Since 2010 it has become the most common aspect ratio for televisions and computer monitors, and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television. This has replaced the old . 

Dr. Kerns H. Powers, a member of the SMPTE Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.7:1) aspect ratio at a time when nobody was creating 16:9 videos. The popular choices in 1980 were: 1.3:1 (based on television standard's ratio at the time), 1.6:1 (the European "flat" ratio), 1.85:1 (the American "flat" ratio), 2.20:1 (the ratio of 70 mm films and Panavision) and 2.39:1 (the CinemaScope ratio for anamorphic widescreen films). 

Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.7:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.7:1. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 (1.3:1) and 2.35:1 (or 64:27, see also for more information), √ ≈ 1.770 which is coincidentally close to 16:9 (1.7:1). Applying the same geometric mean technique to 16:9 and 4:3 yields the aspect ratio, which is likewise used as a compromise between these ratios. 1. What is the most common aspect ratio for TVs?

input: John was an old man who lived in New York City. John used to work at the Post Office before he quit. John has a grandson named Timmy. Timmy came to visit John and brought his friends David, Roger, and Bill. John gave them each a glass of lemonade to drink. 

Timmy wanted his friends to try his grandfather's meat soup. John was known to be a good cook. He enjoyed cooking burgers, fish, pizza, and soup. John's meat soup was his favorite recipe. John asked his grandson to go to the store to buy the food. He wanted Timmy to buy some meat. Timmy took some money from John and went to Kroger. Timmy thought of buying ground beef, chicken, turkey, and sausage. He bought three pounds of ground beef. He took it back to John, who had started making the soup in his kitchen. 

John cooked the ground beef and added it to the soup. They let the soup cook for two hours and then John tested it to see if it was ready to eat. The soup tasted delicious. Timmy and his friends loved it and told John they would be back for more. 1. What is Johns grandsons name
