Article: Strawberry fields dotted with hunched-over workers picking and packaging, then pushing the delicate red fruit to waiting trucks -- it is a typical winter scene embedded in the patchwork of homes and farms that make up eastern Hillsborough County. That scene is changing, though, as the labor pool shrinks and technology comes knocking. Wish Farms owner Gary Wishnatzki and his engineer partner Bob Pitzer are banking on technology. As strawberry season wrapped up in February, their driverless strawberry-picking machine drove into the fields for some test runs. The results were impressive and enlightening , Wishnatzki said. For some three years now, farmers have been forced to abandon millions of dollars worth of strawberries in fields, mostly in Hillsborough and Manatee counties, because they lacked laborers, industry experts say. The problem has been just as serious in California, Arizona and other farm communities. The reasons for the shrinking worker pool are numerous. Migrant workers who have picked the fields for years are aging. Young adults in migrant families already in the United States are getting better educations and have more choices these days, including the construction industry, which again is on the upswing. Stricter security is allowing fewer undocumented workers to cross the border from Mexico. And Mexicans are having much smaller families now -- just over two children per family, compared with 7.3 per family in 1960, according to a Pew Hispanic Center report released in 2012. And since Mexico's economy bounced back faster than that of the U.S., more Mexicans have been able to find work closer to home, according to the study. "We came up with a concept we perceive as a necessity," Wishnatzki said. "The labor pool has been shrinking for over 10 years now. It has been pretty harmful." So in 2012, he and Pitzer formed their partnership, Harvest CROO Robotics, to develop a mechanical picker. The Harvest CROO design has multiple picking heads that will move across a field, picking 25 acres over a... Question: The mechanical picker is introduced due to _ . Yes or no, is the answer "the labor shortage"?
No

Article: Earthquakes are the shaking, rolling or sudden shock of the earth's surface. Earthquakes happen along "fault lines" in the earth's crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted ---- although scientists are working on it! Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs. The intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can't be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Wenchuan Earthquake, which hit Sichuan Province in 2008, was magnitude 7.8. Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP, COVER and HOLD ON. So remember to DROP to the floor and get under something for COVER and HOLD ON during the shaking. Question: Which statement about earthquakes is Not correct? Yes or no, is the answer "Earthquakesusually can be felt because they can last for a long time."?
(Answer)
No

Ques:Article: Everyone hates to wait in lines. We get that anxious feeling that our precious life is slipping away while we're doing something so meaningless. But it's not always the length of the wait we find so unbearable. Some people camp outside Apple stores for an entire night just to get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it. Our behavior when waiting is only partly decided by the length of the wait. "Often the psychology of queuing is more important than the statistics of the wait itself," notes the MIT researcher Richard Larson. One apparent aspect of queuing psychology is that we get bored when we wait in line. This issue is solved in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our appearance. We really hate it when we expect a short wait and then get a long one. But studies show that we are much more patient when we are given an idea of how long we'll be waiting. Walt Disney Co knows this better than anyone else. It posts estimated waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more quickly than they expect. It keeps them happy. But perhaps the biggest influence on our feelings about waiting in a line has to do with our sense of fairness. When it comes to queues, the universally acknowledged standard is first come, first served. Any departure from this principle is regarded as unfair and can lead to violent queue anger. You've probably experienced mild queue anger yourself in fast food restaurants, watching people in the other line zoom ahead of you, cursing yourself for having chosen the "wrong" line. In order to solve this problem, the serpentine line was invented. The serpentine line guides all customers into one big snaking queue, separated by ropes or barriers. When you reach the head of the queue, you are directed to the next available server, or teller, or customs official. The... Question: Serpentine line was invented to _ . Yes or no, is the answer "guarantee the first-come-first-served principle"?

No
