Read the following article and select the best answer. Article: Kayaking is an activity enjoyed by many people of all ages. It requires little or no experience and nearly anyone of any skill level can participate. It's most popular as a summertime sport, but it is also a great activity during the winter. Kayaking also seems ly friendly to the environment; more so than speed boating or water skiing. Because a kayak doesn't create large or frequent waves, require fuel, or scatter hazards into the air, it is indeed a fairly safe activity for humans and wildlife alike. Kayaking on freshwater lakes and streams creates little turbulence and therefore does not disturb fish or other aquatic life. Actually, the gentle paddling and movement of the kayak helps to bring seaweed to the surface, making for convenient snacking to the fish. However, there is a drawback to the all-you-can-buffet for your fishy friends. In addition to bringing food to the surface, kayaking also stirs up litter that's been hiding beneath the waters. Some aquatic animals will mistake it for food. This could cause the animals to choke on the indigestible litter, leading to death. As hazardous as this sounds, it isn't very likely for such an event to take place. Most litter in lakes and streams is found along the shoreline and settles in the sand and dirt, and isn't likely to drift away to the main body of water. ^ . And because kayaks do not have a motor, fish have no risk of getting caught underneath the boat. One potential hazard that results from kayaking is human waste. This depends solely on where you plan to kayak, and if there are resources available (such as campsites) along the shoreline. When there are no facilities in sight, you're paddling in the middle of a lake, and nature calls, then often you are given no choice but to expel your waste in the middle of the water. While human waste is considered biodegradable, it can be harmful when swallowed by fish. The only preventative measure is to avoid using the water as a restroom. Some public lakes and streams have taken steps to preserve the...

Ques: Read the following article and select the best answer. Article: Mr King was the manager of a hotel. One weekend all the hotels in the city were full because there was a large meeting. On Friday night, three men came into the hotel and asked for rooms. Mr King said there were no rooms ready because of the meeting. The men were unhappy. Mr King wanted to help them. He remembered that Room 418, a very small room, was empty. He asked them if they would share a room. The three men said they would. Mr King said the room would be thirty dollars: ten for each one. Each man gave him the money and then went up to the room. Mr King soon began to feel sorry. "Thirty dollars is a lot to ask as price for that small room. " he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself. The men will be happy to get something back, and Mr King will never know. " So the assistant returned one dollar to each man. Each man had at first paid ten dollars. After the assistant returned them one dollar each, each had paid nine. There were three men, $ 9 x3 = $ 27. The assistant kept $ 2. $ 27 + $ 2 = $ 29. Where is the missing dollar? Question: With the help of the manager, the three men _ . - went to another hotel - each got a small room for the night - stayed together in a small room - got a small room Mr King kept for himself
Ans: stayed together in a small room

Read the following article and select the best answer. Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution--a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. "We were praying to the parking god that we'd find a spot," she said. "If we had the app, we would not have to pray to the parking god." But the system could come with serious consequences. Some people say that drivers searching for parking could end up focusing on their phones, not the road. "It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone but which city officials say they hope to bring to all similar... Question: According to the text, San Francisco city officials _ . - don't consider the app distracting - advise drivers to park cars slowly - are aware of the app's disadvantages - believe more parking spots are needed
