Problem: Given the question: Write a multi-choice question for the following article: Article: Hiking is not only one of the best forms of physical exercise, but it is also one of the best forms of mental relaxation. It is good for all ages and especially good as a family and group activity. Since there are so many different kinds of hiking, it is not possible to give any general rules to follow. Short and frequent hikes, needing no planning or special equipment, are enjoyed by most people. *Keep in shape by walking at a fast pace for at least 15 minutes every day. Climbing stairs instead of using a lift and running not too far are also good ways of keeping in shape. *On any hike nothing is more important than good, comfortable shoes. *The things you take might include matches in a waterproof box, a knife, compass, map first aid items and flashlight. *Cameras may be taken, but don't load with too much. *On longer hikes keep a comfortable, steady pace and take rest stops often. *Drink only safe water. If in doubt, boil the water. *Don't go along the busy roads. When you have to use a road, keep as far over on the left as possible. *Leave word at home or some other place as to where you are going and when you plan to return. *On almost any hike, a map is a good idea. If going into a strange place, a detailed map is most useful. *Take along a field guide on flowers, birds, rocks, or other subjects depending upon your interests. This can add greatly to the enjoyment and educational value of your hike.

Problem: Given the question: Write a multi-choice question for the following article: Article: Picking tomatoes For as long as I can remember,Grandma's plentiful tomato garden has been a sign of summer's end.Each September,just as the decreased heat of the sun suggests cooler days,Grandma requests my help in her tomato garden.She convinces me she cannot pick tomatoes without my youthful eyes and quick mind.She says we need to examine each tomato and agree on its readiness for picking.While Grandma's request for my help in the tomato garden is always the same,her desire for my help seems to increase each year. Grandma has eyes for finding even the tomatoes hidden by undergrowth and other tomatoes.I,however,just turn circles looking for the ones I think Grandma will like.I spot what looks like a ripe tomato,head in its direction,and then get sidetracked by another that appears to be equally ripe.I usually end up watching Grandma and trying to stay out of her way,which seems the only way my eyes and mind are useful. There we are,lost in the tomato vines .Grandma's eyes are always knowing,and they are no different in the vegetable garden.From afar she spots what looks like a ripe tomato.As she walks toward the garden,she evaluates the tomato for a second time,but from a different angle.I already know it will end up in the basket with the pile of others Grandma has carefully chosen.However,Grandma acts as if she needs final look to be sure.She calls me to her side,kneels beside the vine while enjoying the warmth of the fading sunlight on her face,and grasps the tomato in her hand.She turns each round,red ball toward the sunlight before disconnecting it from the vine with a halfhearted smile. She then looks at me.I nod my head and smile.Grandma assumes I smile in agreement with her tomato selection.I know I smile,instead,at her.

Problem: Given the question: Write a multi-choice question for the following article: Article: Do you know anything about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back. It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree. Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand -- no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why? A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this example studying tree rings uncovered an exciting fact about the history of man.
