Example Input: Article: My husband and I were once in Nepal to see sunrise over the Himalayas. One morning we awoke to total darkness at 5 o'clock.As we rushed through a town with cameras in hand,I noticed the calm,gentle way the Nepalese people greeted the morning.One man boiled a huge pot of milk tea,and other villagers gathered around his fire,cupping their hands around small glasses of the steaming sweet mixture.It was fascinating,but not to be left behind,we joined the stream of tourists moving quickly up to the lookout point. The top was crowded when we arrived,but after 10 minutes of cold waiting,the assembled group gave up."The cloud cover is too heavy,"one said.Then one by one they rushed down the hill to the next item on their sightseeing list.I was disappointed as well,but suddenly I noticed a small Nepalese boy absently playing with a stick and shooting quick glances at the clouds.He must know something we don't,I thought.I decided to wait with him. The boy and I didn't have to wait long.Moments later,a tiny stream of golden light burned through one thick cloud,then another.Rose-colored fog warmed the backs of the clouds,and suddenly the morning sun stole a glance around the side of the mountain,mile above where I'd expected it to be. Nothing I'd seen before prepared me for the moment the clouds withdrew with bowed heads,and the magnificent Himalayas were revealed before,around,and above me.I sat in astonishment,not breathing,not daring to look away,certain that God had placed me here at the backdoor of Earth to show me what Heaven really looks like.I certainly got the message.Never again will I rush a sunrise.I now know Nature will supply her fruits to me only when I am truly ready to receive them.

Example Input: Article: Learning to play a musical instrument can change your brain, with a US review finding musical training can lead to improved speech and foreign language skills. Although it was suggested in the past that listening to Mozart's music or other classical music could make you smarter, there has been little evidence to show that music can boost brain power. But a data-driven review by Northwestern University has pulled reaserch together that links musical training to learning that spills over into skills including language, speech, memory, attention and even vocal emotion. Researcher Nina Kraus said the data strongly suggested that the nervous connections made during musical training also prepared the brain for other aspects of human communication. " The effect of musical training suggests that, like physical exercise and its effect on body fitness, music is a resource that tones the brain for _ fitness and thus requires society to re-examine the role of music in shaping individual development, " the researchers said in their study. Kraus said learning musical sounds could improve the brain's ability to adapt and change and also enable the nervous system to provide constructing patterns that are important to learning. The study, published in Nature Review Neuroscience , looked at the explosion of research in recent years focusing on the effect of musical training on the nervous system which could have impacts for education. The study found that playing an instrument prepares the brain to choose what is related in a complex process that may involve reading or remembering a score, timing issues and coordination with other musicians.
