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,"...

Question: Read the following article and answer the question. Article: Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were our in our front yards, watching seven children of age six and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie. Then we worked out a plan. When Christie takes one of her children out alone, I'll watch her other three. And when she watched two of mine, I will take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She is like a different kid when there's no one else around," Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make any effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I'm always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who is always a follower when around other children, shines a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child--talking, sharing and laughing, which has been the biggest gain. Every child deserves an only child at least once in a while. Question: What's one of the changes the author finds in her children? Answer:
OPTIONS:
- Tom has less difficulty in speaking.
- The daughter acts like a leader.
- Sam holds her hand more often.
- The boys become better followers
Answer: Tom has less difficulty in speaking.

Question: Read the following article and answer the question. Article: At Denver there was an crowd of passengers into the coaches on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank face expression and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed together. As they passed down the aisle of the coach the only available seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman's glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her face and a tender pink tingeing(,) her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard. "Well, Mr. Easton, if you will make me speak first, I suppose I must. Don't you ever recognize old friends when you meet them in the West?" The younger man aroused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand. "It's Miss Fairchild," he said, with a smile. "I'll ask you to excuse the other hand; "it's otherwise engaged just at present." He slightly raised his right hand, bound at the wrist by the shining "bracelet" to the left one of his companion. The glad look in the girl's eyes slowly changed to a bewildered horror. The glow faded from her cheeks. Her lips parted in a vague(,), relaxing distress. Easton, with a little laugh, as if amused, was about to speak again when the other forestalled him. The glum-faced man had been watching the girl's face expression with veiled glances from his keen, shrewd eyes. "You'll excuse me for speaking, miss, but, I see you're acquainted with(,) the officer here. If you'll ask him to speak a word for me when...
