Read the following article and answer the question. Article: In many romantic movies or TV shows one scene always appears. It involves a handsome man standing outside a young woman's window, singing a love song to her to win her over. However, trying to woo a female with songs is not just something that humans do. A few animals sing love songs as well. Birds and elephants are romantic but the latest animal to _ a female might surprise you--it is the humble mouse. You may find it odd to find out that mice sing. We do not hear them because the frequency of their voice is so high. In fact, scientists have known for some time that male mice make special sounds to females, but it has always been assumed that the sounds are produced instinctively and randomly, with little thought going into the process. But new research suggests otherwise. When male mice with different voices were put in a cage together, scientists found that they would gradually change their pitches to sound like one another. But when a female mouse was put in the cage with two males, one male would change his pitch to match the other. "It was usually the smaller animal changing the pitch to match the larger animal," professor Erich Jarvis, leader of the study, from Duke University, US, told BBC News. This ability, known as vocal learning, is rare in the natural world. It had been thought to be limited to some birds, such as parrots--as well as whales and dolphins. The latest findings challenge the long-held opinion that mice cannot learn to adapt their voices. Scientists also found the part of the brain that controls the mice's singing ability. In the experiment, they damaged the cells in this part of the mice's brain and found that the animals couldn't keep their songs in pitch or repeat them any more. This also happened when the mice became deaf. Jarvis said that this finding had changed his understanding of the way mice make sound. "In mice we find that the pathways that are at least modulating these vocalizations are in the forebrain, in places where you actually find them in humans,"...

Read the following article and answer the question. Article: The surgeries went well, and not long afterwards, my sister and I were allowed to go in to visit. Dad was in a great deal of pain but, again, all he could talk about was Mom, who donated her kidney to him. Was she okay? How was she feeling? As they were wheeling Mom out of the recovery room, they rolled her into a separate place in Dad's to visit him. It was like a dream to see both our parents hooked up to IVs and machines and trying to talk to each other through tears. The nurses allowed us to present the diamond ring, which was purchased by Dad before the surgery, to Mom so that Dad could watch her open it. Everybody was crying, even the nurses. As I stood with digital camera in hand, I tried to keep the presence of mind to document the moment. My dad was having a hard time fighting back emotion, and suddenly my parents reached out to hold each other's hands. In my nearly 35 years of existence, I'd never seen my parents do that, and I was absorbed in. I snapped a picture and later rushed home to make sure I'd captured that enormous, life-defining moment. _ . After so many years of quarrels, it was apparent to me that they finally understood how much each loved the other actually . It's as if the transplant healed our whole family. Dad is far gentler, and he has more patience now. He's not condescending to my mother anymore. Mom, too, has loosened up, since she's not dealing with all that anger. There's a closeness that they didn't have before, and the experience has deepened their faith. For Christmas, my sister and I gave them two framed photos linked together by hooks. The top photo is of their clasped hands on their wedding day, August 7, 1965. It says, "For better or worse, for richer or poorer." The second photo is of that day in the recovery room. Their hands are intertwined and it says, "In sickness and in health, till death do us part." Question: From the story of the author's parents we can conclude that _ . Answer:
