Question: Write a multi-choice question for the following article: Article: "Look! Here come UFOs!" At around 8 p.m. July 26,2010, a citizen called Lu Shan spotted this special phenomenon in Leshan, Sichuan: three unidentified and bright objects appeared in the sky above "Jade International" building, and then disappeared all together after 10 more minutes. The phenomenon caught a lot of attention of some experts and Leshan citizens. On August 3, Professor Wang Sichao from the Purple Mountain Observatory of the Chinese Academy of Sciences said, the objects still need to be identified. Luckily, Lu Shan took some photos of it. He described, the objects first lit up the sky in the west, but lasted for about 10 minutes. Then they moved slowly at a speed of I meter per minute to the north, and became smaller and smaller until they disappeared. "It was like a sunset before they faded, and their light also became so gentle as the sunset." Some citizens doubted they were UFOs, but Lu Shan thought it was possibly caused by the refraction of the sunlight. However, Lu found no scientific proof to support this special phenomenon after comparing with his photos. According to Professor Wang Sichao, it could be the "sun dog " which is an atmospheric phenomenon that creates bright spots of light in the sky, often in a bright ring or _ on either side of the sun. But he also added the sky above Leshan city that night did not satisfy the conditions to have "sun dog". "Sun dog" usually happens in cold areas, such as the north and south poles of the earth. "So this phenomenon was strange," said Wang Sichao. Wang also stated he's only able to confirm the identity of the objects after collecting and analyzing more information and photos snapped from different locations and then decide on a more scientific explanation.

Question: Write a multi-choice question for the following article: Article: As long as you have broadband service in your home, you can turn on your desktop computer and connect to the Internet. If you have a wireless router , a device that spreads the broadband connection to other devices, you can set up a Wi-Fi network, which enables your cellphones and tablets go online too. And when you are outdoors where is no Wi-Fi, such as in the park or at the beach, having 3G service allows you to stay connected. It seems that lots of us have Internet coverage everywhere we go. So why have mobile companies around the world lately been so enthusiastic about a new term, "4G"? First, you need to know that the letter :G" stands for "generation". Even if you have no idea what 4G is, at least you can figure out that it is a step up from 3G since it's the latest generation of mobile internet service. Unlike broadband, mobile Internet uses the same signal towers that provide voice service to your cellphone, which means wherever you can make phone calls with your cellphone you also have an Internet connection. But mobile connections have their _ : they don't carry as much information as broadband does, making opening websites and downloading music slower than they are on a Wi-Fi connection. This is why mobile connections have been constantly upgraded since the first generation was launched back in the 1980s. According to BBC, 4G is five to seven times faster than current 3G network speeds, almost as fast as home broadband. Because of this, 4G is widely suited for services like video downloading, mapping, online shopping and even video conferencing. To achieve the high speeds, network companies have to spend a lot of money on building new signal towers, which will eventually lead to a higher phone bill if you switch to 4G, and you will also have to get a new phone with 4G capacity.
