How does the setting of a life at sea in Selection 1 affect the character?A)He lives a life of unmatched ease.B)He leads a life of great adventure.C)He has many unmet needs.D)He is in constant fear.(the POEM)I must go down to the seas again, to the lonely sea and the sky,And all I ask is a tall ship and a star to steer her by,And the wheels kick and the winds song and the white sails shaking,And a gray mist on the seas face and a grey dawn breaking.I must go down to the seas again, for the call of the running tideIs a wild call and a clear call that may not be denied;And all I ask is a windy day with the white clouds flying,And the flung spray and the blown spume, and the sea-gulls crying.I must go down to the seas again, to the vagrant gypsy life,To the gulls way and the whales way, where the winds like a whetted knife;And all I ask is a merry yarn from a laughing fellow-rover,And quiet sleep and a sweet dream when the long tricks over.
The sun is closer to Earth than any other star.What evidence from the passage supports this statement?- read this- After the sun sets, take a look at the night sky. On a clear night, youll be able to see stars scattered across the black expanse that we call our universe. If youre lucky, you might be able to spot some stars that look bigger than othersthey shine brighter and attract our attention more than their smaller neighbors do. You might wonder: why are some stars brighter than others?After much observation, scientists discovered the way stars appear to us depends on more than their actual sizeits also about how far they are from us. Therefore, the farther a star is from Earth, the smaller it will appear to us. The closer it is, the bigger it will look.Try to think of the biggest star youve seen in the sky. An easy one, right? The sun! Thats because the sun is closest to us compared to all other stars, located at just a short 150 million kilometers from Earth.The next one? Thats a tougher question. Many people answer Alpha Centauri, but some dont know that its actually a cluster of three starsAlpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is 4.24 light-years away and closest to our sun. A light-year is the distance that light travels in one year. We use this measurement because light is the only thing in the universe that maintains a constant speed. However, even though Proxima Centauri is the closest star to the earth after the sun, you can only see it with a very powerful telescope. That doesnt make sensedidnt we just say that closer stars appear larger and more visible?Well, Proxima Centauri is what we call a red dwarf. Red dwarf stars are very small, typically having less than half the mass of the sun. That means they generate less energy than the sun. Most stars burn hydrogen for fuel. Similar to the way a car uses gas for power, a star uses hydrogen for energy. Red dwarfs burn hydrogen very slowly, which means they generate little light compared to stars like the sun.Proxima Centauri is the closest star after the sun, but that doesnt necessarily mean its what we consider close in our minds. To completely understand how far away this star is, lets think about traveling 4.24 light-years away. NASA has built one of the fastest spacecrafts in existence, called New Horizons, which travels at about 60,000 kilometers per hour. Even at this speed, it would take the spacecraft 78,000 years to reach Proxima Centauri from Earth.Sadly, the first few closest stars are not visible to the naked eye at night, which means we cant see them while were stargazing from our homes or backyards. The closest star we can see at night is called Sirius, or the Dog Star. While Proxima Centauri is only 4.24 light-years away, Sirius is 8.6 light-years away. However, since Sirius is so large (almost twice the size of the sun), we can see it in the night sky.So go outside and see what you can find up there!
