Read the following article and answer the question. Article: Dear iPhone 4 Users, The iPhone 4 has been the most successful product in Apple's history. It is the best smartphone ever, and most users have told that they love it. So we were surprised when reading reports of reception problems, and we immediately began researching them. To start with, holding tightly almost any mobile phone in certain ways will reduce its reception by 1 or more bars of signal strength. This is true of iPhone 4, iPhone 3GS, as well as many other phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way. This is a far bigger drop than normal, and as a result some have said the iPhone 4 has a faulty antenna design. Upon research, we find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula usually mistakenly displays 2 more bars than it should for a given signal strength. The big drop in bars is because the high bars were never real in the beginning. We will give a free software update to correct the formula. This software update will also be available for iPhone 3GS. If you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of buying and get all your money back. Thank you for your patience and support. Apple Question: The text is a letter _ . Answer:

Read the following article and answer the question. Article: Roll over, sit and fetch aren't commands normally given to a robot, but the smart toy company WowWee has developed a new way of owning a puppy. CHIP (Canine Home Intelligent Pet) is a robotic dog with blue LED eyes and pointy ears and can sit, shake, dance and make all types of dog noises. It also has tracking capabilities to help locate its owner. "The beauty about CHIP is that it has its own thing going on," said Sufer, CTO at WowWee. "It has its own life and own kind of intelligence. Even if you're not around, it's always doing something." CHIP uses wheels to get around and is loaded with sensors that give it a 360-degree view to find its ball. The pup is Bluetooth enabled, which connects to a wristband worn by its owner. The wristband, similar to a watch, displays icons for different commands such as a thumb-up, which allows you to give your pup a digital belly rub. With its owner wearing a smart wristband, it can even follow him around the room. "We worked on CHIP for about five to six months," Davin Sufer, told dailymail.com, "We typically come up with a concept, model and product and get it on shelves within a year." The company plans to start shipping units by next fall, which will allow them to load up the robotic dog with sensors and add many more animated responses per-owner interactivity. The high-tech toy company made its debut in 2004 by releasing the 1.5 foot RoboSapien, which sold millions of units. MiP, which hit shelves last year, is a seven inch tall robot covered in white with black accents. Users can direct it, change its emotions and make it dance to any song on your iPad. It's loud, fast and active. About 15 years ago, a company called ToyQuest developed the first ever electronic robotic dog---Tekno, the Robotic Puppy. The company sold over seven million units in the first season and 40 million more during its original four years of production. Tekno was built with over 160 emotions and instructions, but most importantly offered consumers a quick look into the future. Question: CHIP can follow its owner with the help of _ . Answer:
OPTIONS:
- a watch
- a smart wristband
- pointy ears
- blue LED eyes

Answer: a smart wristband

Read the following article and answer the question. Article: Many Western people are not used to sitting on the floor any more. In Japan, however, sitting upright on the floor is common in different situations. For example, meals are traditionally had when people sit on the tatami floor around a low table. Also during the tea ceremony and other traditional events, one sits on the floor. The formal way of sitting for both men and women is kneeling upright. People who are not used to sitting in this style may feel uncomfortable after a few minutes, and their legs may go numb. However, foreigners are not usually expected to be able to sit in this style for a long time, and an increasing number of Japanese people themselves aren't able to do so, owing to a more westernized lifestyle. In other situations, men usually sit cross-legged, while women sit on their knees laying both legs to one side. The former sitting style is considered wholly male, while the latter is considered completely female. The most important guest sits on the honored seat which is set farthest from the entrance. If there is a tokonoma in the room, the guest should be seated in front of it. The host or the least important person is supposed to sit next to the entrance. Of course, there are other things to be considered in each particular case. Question: When some guests are in a Japanese home, _ should sit nearest to the entrance. Answer:
OPTIONS:
- the most important guest
- both the host and the hostess
- the host or the least important person
- the host himself

Answer:
the host or the least important person
