Read the following article and select the best answer. Article: It is a tall tale that terrifies most young children. Swallow a piece of chewing gum and it will remain in your body for seven years before it is digested. An even worse tale is that swallowed gum can wrap itself around your heart. But what does happen if you should accidentally eat a stick of gum? Chewing gum is made out of gum base, sweeteners, coloring and flavoring. The gum base is pretty indigestibleit is a mixture of different ingredients that our body can't absorb. Most of the time, your stomach really cannot break down the gum the way it would break down other foods. However, your digestive system has another way to deal with things you swallow. After all, we eat lots of things that we are unable to fully digest. They keep moving along until they make it all the way through the gut and come out at the other end one or two days later. The saliva in our mouths will make an attempt at digesting chewing gum as soon as we put it in our mouths. It might get through the shell but many of gum's base ingredients are indigestible. It's then down to our stomach muscleswhich contract and relax, much like the way an earthworm moves to slowly force the things that we swallow through our systems. Swallowing a huge piece of gum or swallowing many small pieces of gum in a short time can cause a blockage within the digestive system, most often in children, who have a thinner digestive tube than adults but this is extremely rare.

But other people feel regret that no human has been back to the moon since 1972, just three years after Armstrong landed on it and gave his famous "giant leap for mankind" speech. Elliot Pulham, Chief Executive of the Space Foundation, thinks that America's space agency NASA should get more money, like in the 1960s, during the moon landings programme, when astronauts went to the moon. "In this age of limited goals and tiny NASA budgets, Armstrong is a reminder of what our nation was once capable of," he said.  Armstrong died because of heart problems after surgery. His recovery seemed to be going well, and his death was a surprise to many people. His family described him as a "reluctant American hero" and said: "Honour his example of service, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink." Speaking from the White House, Barack Obama said Armstrong was "among the greatest of  American heroes - not just of his time, but of all time". He added: "And when Neil stepped on the  moon for the first time, it was a moment of human achievement that will never be forgotten." Buzz Aldrin flew with Armstrong on Apollo 11. He was the second man to walk on the moon. He said he was very sad at the death of his good friend and companion. "When I look at the moon I remember that special moment, over forty years ago, when Neil and I stood on the moon," he said. "Looking back at our brilliant blue planet Earth hanging in the darkness of space, I realized that even though we were farther away from Earth than two humans  had ever been, we were not alone. Almost the entire world took that memorable journey with us. I know many millions of people around the world will join me in mourning the death of a true  American hero and the best pilot I ever knew. My friend Neil took the small step but giant leap that changed the... Question: How, according to Buzz Aldrin, will Armstrong's 'giant leap' be remembered? - as a historic moment that changed the world - as a memorable journey with the whole world watching - as a representation of the achievements of a past age - as a story that can not be repeated for human being
(A).
as a historic moment that changed the world

Read the following article and select the best answer. Article: After moving to a small town, I took several pairs of shoes to the shoemaker to be fixed. Within a week I picked them up and put them away in my closet. Four months later my husband and I were invited out to dinner. I unboxed a pair of high heels . I hadn't worn them since they were repaired. I put one shoe on my right foot, and then I put the other on my left. I took both shoes off for a closer look. They were exactly the same style, color1 and size, but each was for the right foot. I was puzzled, since I had worn the shoes on several occasions and knew I hadn't worn two right shoes. Then I thought of the shoemaker. Although I was sure he wouldn't remember me after such a long time, I telephoned him and explained to him the trouble I had. "Thank goodness you finally called!" he was nearly shouting, "An angry woman with two left shoes has been bothering for months!"
