Read the following article and answer the question. Article: Brooke Martin's golden retriever Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: --What if you could talk to your dog if you were gone? Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. --The dog doesn't have to answer the call,explains Brooke. --It comes up immediately on the screen on their end. It's a two-way audio and video--you can see and hear each other.With a click of a button you can even send the dog a treat! Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn. After Martin's video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M's consumer health care division. --I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog's end with a dog treat device the owner can remotely activate. One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws. The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards... Question: What do the inventions of the finalists have in common? Answer:

OPTIONS:
- They are all new inventions dealing with pets.
- They are possible solutions to everyday problems.
- They cope with the problems related to computers.
- They are all accomplished through individual work.

Answer: They are possible solutions to everyday problems.

Q: Read the following article and answer the question. Article: Bolivia has a population of three and a half million. About one tenth of the total population are white; one-fourth are mixed Indians and white; and more than half are full-blooded Indians. The government and the industries are under the control of the white people. The Indians today live in much the same way as their ancestors. Most of them are farmers. Many work in the mines, for mining is the most important industry on Bolivia's. Of all the mining products, tin is the most important, which makes up three-fourths of all Bolivia's exports. The eastern slopes of the Andes, since there are very few roads there, are fertile but not highly developed. The two primary means of transportation are river boats and porters. East of the hill region is the great plains where tropical plants are grown. A serious problem for Bolivia is the transport of food from the warm regions, where it is grown, to the mountainous regions, where most of the people live. Bolivia gained its independence from Spain about a hundred years ago. It has been slow in developing, but its rich resources promise a better future in it. Question: The main product Bolivia exports is _ . Answer:
Answer: tin

Read the following article and answer the question. Article: How Do Animals Catch their ZZZ's ? Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping. Gorillas like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed. Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest. They just lock their feet around a branch and hang on. A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall. Dolphins live underwater, but must come to the surface to breathe. Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open. Question: How do dolphins breathe? Answer:
****
A: They come to the surface to breathe.

input with options: Read the following article and answer the question. Article: Our lives were supposed to be more flexible and family-friendly thanks to the technology at our fingertips. But in this age of BlackBerrys, recession pressures, working at home after hours and on weekends, family time may not be working out the way we thought. Busy parents who expected more time with the kids are Finding that more work hours at home don't necessarily translate into quality time with them. A new generation of parents needs to discover the meaning of "quality time," researchers say. "Personally, just given the life I lead, I think there is something to this idea of quality time- spending productive time with children vs. just being around," says Peter Brandon, a professor at Carleton College. He says engaging or interacting with a child in activities such as reading or playing counts as quality time rather than "passive monitoring," such as washing the dishes while the child is watching TV. " _ ," Brandon says. He notes that good parent-child relationships result in children being happier and more successful, including at school. As parents struggle to be more available to their kids, new research on work and family schedules to be presented Friday at the meeting in Dallas includes a study that shows parents' availability is on the decline because more parents are in the workforce. Although parents today may be spending more time on child care, they are less available overall. Working parents who spend less time with their children should try to make sure the time they do spend is communicating with them, vs. doing the dishes or spending more time on themselves, Brandon says "The trade-off is not necessarily taking away time from your kid," he says "You're taking away time from other things" Question: What will the author most probably talk about in next part of the passage? Answer:
OPTIONS:
- How to spend more time at home
- How to do the dishes in a proper way.
- How to spend more time on working at home.
- How to take away time in a much proper way.
output:
How to take away time in a much proper way.
