Read the following article and select the best answer. Article: Humans: It's time to abandon the earth or face extinction. This prediction isn't science fiction. It's a glimpse of the future, according to famed British scientist Stephen Hawking. "I see great dangers for the human race," he said in an interview with global forum Big Think. "There have been a number of times in the past when its survival has been a question of touch and go ." Hawking says humans must _ our home planet within the next two centuries and expand into space to survive. "I believe that the long-term future of the human race must be in space," he said. "It will be difficult to avoid disaster on our planet Earth in the next hundred years, let alone the next thousand, or million." He also voiced some concerns about the future of life on the earth. In April, he spoke about his fear of aliens in an interview for the Discovery Channel. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said. "Such advanced aliens would perhaps become wanderers, looking to conquer and colonize whatever planets they can reach." But Hawking says he is still hopeful for the future of humanity. "I'm an optimist," he told Big Think. "We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space." Getting to another planet will prove a challenge, not to mention colonizing it for humanity. University of Michigan astrophysicist Katherine Freese told Big Think that "the nearest star to Earth is Proxima Centauri which is 4.2 light years away. That means, if you were traveling at the speed of light the whole time, it would take 4.2 years to get there" --- or about 50,000 years using current rocket science. Question: Despite some concerns, Hawking's attitude towards the future of humans is _ . - objective - negative - subjective - positive
positive

Read the following article and select the best answer. Article: I decided to have dinner in the hotel, for I arrived late one night on a business trip. As I was finishing my meal, an elderly couple came in to dine. They were holding hands and had lovely smiles on their faces. They sat three tables from me. I was amazed at the love they showed for each other. It seemed to strike home all the more, because it was shortly after ending a 20-year marriage and I still had pain in my heart. My waiter was also their waiter. As I paid my bill, I inquired as to what their bill was. He informed me, and I gave him $40 to pay their bill. He asked if I knew them and I told him "No, I just wanted to repay them for the love that they were showing to each other," and then I departed. The next day I entered the restaurant to dine before my departure. After I had been seated, the waiter who served me the night before told me that the strangest thing happened after I left the restaurant. When the elderly couple went to pay for their meal, they were informed that it had been paid. When they inquired who had done this, the hostess told them they had no idea who I was, just retelling what I said. The couple were amazed. They looked around, asked for the bill of two young couples who were seated together, paid their bill and departed, saying "Love begets Love" to the amazement of the hostess and waiter. I smiled and said "That's nice," and proceeded to order my meal. About 45 minutes later, I finished my meal and was about to head out, but my waiter was nowhere to be found. I waited and waited and finally walked over to the hostess stand and explained that I needed to pay for my meal and hurry to the airport. She smiled and explained that I would not have to pay for my meal, because both the waiter and she felt compelled to pay my bill due to the joy that was brought to the faces of the elderly couple and the amazement of the young couples. When I told her that they didn't have to do that, she said with a smile "Love begets Love." Question: Which of the following proverbs can best explain the theme of the story? - A good beginning makes a good ending. - Where there is love, there is life. - Love me, love my dog. - As a man sows, so shall he reap .
As a man sows, so shall he reap .

Read the following article and select the best answer. Article: After a very busy afternoon,as I walked into my house,I heard the phone ringing. It was my friend Lydia,upset over an argument with her husband. My usual approach is to offer advice,but this time,exhausted from chores,I simply sat down in a chair and listened to my friend's frustration and sadness. Without the disturbance of judgment or the desire to comfort her,I stayed totally quiet while she talked. Eventually Lydia's depression eased and we said our goodbyes. The next day she phoned to thank me. "I'm so grateful for the way you helped me through this,"she said. At first I was surprised. After all,I had done nothing except be there for her. But after I had my own venting experience with another friend later that evening,I realized that my focused silence had some value. In fact,most relationship experts agree that talk is cheap;it's listening that's rare and valuable It allows you not only to hear what the other person is saying,but also to have a clear understanding of her thoughts and feelings. And for the speaker,that level of understanding translates into concern and respect. Unfortunately,listening isn't as easy as it sounds. Thanks to schedules filled with family and work,multitasking has become a barrier to listening. My tiredness may have been the only thing stopping me from folding laundry or checking my email while Lydia talked that afternoon. Another barrier to listening is our listening system:Most of us take in only about half of what's being said during a conversation,according to the International Listening Association. Research shows that we speak at 125 to 150 words per minute,yet think at 500 words a minute. Therefore,because we think much more quickly than we speak,it is easy for us to lose our concentration when listening to speakers. While it can be hard to focus at times,it's a skill worth developing. With a little practice (employing some techniques),you can become a better listener. Question: Why didn't the author give any advice to Lydia that afternoon? - Because she thought her keeping silence was better for Lydia. - Because she didn't know how to comfort Lydia. - Because she was too tired to talk to Lydia. - Because she couldn't cut in while Lydia was talking.
Because she was too tired to talk to Lydia.
