Question: Read the following article and select the best answer. Article: I was going on vacation to meet up with family for a week of fun in Denver. I got to the airport, ready to leave my work behind for a few days.       I was comfortably awaiting my flight with a good book to read, when an elderly lady was wheeled to our waiting area. I couldn't help but notice the trouble she was having trying to open a packet of nuts with her shaking hands. I sighed. No one else was willing to meet her gaze   so I offered to help.        She was very grateful. It turned out that these nuts were her entire breakfast. We sat and chatted. When the time came to board the plane the attendants   were nowhere to be seen. The lady could walk but needed some help, so I volunteered to help her on the plane and carry her bag.      As I helped her get settled I noticed her "seat mate," a businessman, looked a bit horrified at having to make the fight with her. He offered to change seats with me -- and I agreed.       We landed and I needed to change planes, but I helped her disembark   first. The wheelchair she ordered was nowhere to be seen so we slowly walked to gate where her daughter was waiting.      We only exchanged first names, and she was so grateful to have my help. I had to run to catch my connection but, as I thought about the experience, I saw her as my airport angel: a chance for me to hope that in the future when I'm in my 80's and traveling, someone will take the time to connect with me. Pay it forward. Question: Why does the author feel grateful? - He believes he may find help if he is in need later. - He was appreciated deeply by everyone nearby. - He was looking forward to live up to 80 as the old lady. - He can get paid forward later in money.
Answer: He believes he may find help if he is in need later.

Question: Read the following article and select the best answer. Article: If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory  is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault . But if he tells us that he has a poor memory, many of us think that his parents are to blame , and few of us know that it is just his own fault. Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and they have to remember things they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering. Question: The main reason for one's poor memory is that   _  . - his father or mother may have a poor memory - he does not use his arm or legs for some time - his memory is not often used - he can't read or write
