Article: If you are sending a text, watching the TV or listening to the radio, you may want to stop and give this your full attention. Multi-tasking shrinks the brain, research suggests. A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, "Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains." The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school. The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the web. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulate cortex (ACC). The findings held even when differences in personality were taken into account. The study, published in the journal PLOS ONE, is the first to make a link between multi-tasking and the structure of the brain. Researcher Kep Kee Loh said, "Media multi-tasking is becoming more common in our lives today and there is increasing concern about its impacts on our cognition and social-emotional well-being." He added that more research is needed to prove that multi-tasking shrinks the brain. This is because it is also possible that people with less grey matter in the ACC are more drawn to using lots of small devices simultaneously. Scientists have previously demonstrated brain structure can be changed on prolonged exposure to new environments and experience. Other studies have shown that training -- such as learning to juggle or taxi drivers learning the map of London -- can increase grey-matter densities in certain parts. Experts have also warned of the harmful impact technology can have on... Question: According to Kep Kee Loh, _ . Yes or no, is the answer "the link between multi-tasking and brain shrinkage needs further research"?

Article: Every April I am troubled by the same concern -- that spring might not occur this year. The landscape looks dull, with hills, sky and forest appearing gray. My spirits ebb, as they did during an April snowfall when I first came to Maine 15 years ago. "Just wait," a neighbor advised. "You'll wake up one morning and spring will just be here." And look, on May 3 that year I awoke to a green so amazing as to be almost electric, as if spring were simply a matter of flipping a switch. Hills, sky and forest revealed their purples, blues and green. Leaves had unfolded and daffodils were fighting their way heavenward. Then there was the old apple tree. It sits on an undeveloped lot in my neighborhood. It belongs to no one and therefore to everyone. The tree's dark twisted branches stretch out in unpruned abandon. Each spring it blossoms so freely that the air becomes filled with the scent of apple. Until last year, I thought I was the only one aware of this tree. And then one day, in a bit of spring madness, I set out with pruner to remove a few disorderly branches. No sooner had I arrived under the tree than neighbors opened their windows and stepped onto their porches. These were people I barely knew and seldom spoke to, but it was as if I had come uninvited into their personal gardens. My mobile-home neighbor was the first to speak."You're not cutting it down, are you?" she asked anxiously. Another neighbor frowned as I cut off a branch. "Don't kill it, now," he warned. Soon half the neighborhood had joined me under the apple tree. It struck me that I had lived there for five years and only now was learning these people's names, what they did for a living and how they passed the winter. It was as if the old apple tree was gathering us under its branches for the purpose of both acquaintanceship and shared wonder. I couldn't help recalling Robert Frost's words: The trees that have it in their pent-up buds To darken nature and be summer woods One thaw led to another. Just the other day I saw one of my... Question: In Para. 4, "neighbors opened their windows and stepped onto their porches" probably because _ . Yes or no, is the answer "they were concerned about the safety of the tree"?

Yes
