Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Hiking can be a pleasant as well as a not so pleasant adventure. You will have to take a number of measures so that your hike is a pleasant experience. Hiking Tip 1 -- Start Early Most hiking experts hold the opinion that it is rather sensible to start hiking at 3 or 4 in the morning, even if it is a full-day hike. Since most hikes are conducted at high altitudes, starting off early will make sure that you are back down during the afternoon hours. Hiking Tip 2 -- Be Light Since we are anyway talking about the load you will carry, another important hiking tip is to carry fewer loads. If you are going on a hiking trail on a familiar path, you will need reduced survival items, as chance that you will get lost or hurt yourself on these hiking trails is little. Hiking Tip 3 -- Reduce the Number of Breaks Once you start your hike, you should make sure you do not take too many breaks. You will need to maintain a consistent speed and minimize the number of stops which you take. Speed and rest stops help distinguish an inexperienced hiker from an expert hiker. An inexperienced hiker will have bursts of speed and energy and it will be followed by rest stops. This results in slowing down the general speed. Hiking Tip 4 -- Tip for Children Do you plan to take your kids along with you on the hiking trail? Well, then you must be looking for hiking tips for kids! You will have to educate them about nature and also get them into an exercise routine before taking them on a hike. Kids have a tendency to run in the beginning. This exhausts them and they have to be carried, which is certainly not the best of ideas. Options: A make sure of his safety B prepare him for it C educate him about hiking D give him some tips Answer: B prepare him for it Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: How often do you sit still and do absolutely nothing.The usual answer these days is"never".or"hardly ever".As the pace of life continues to increase,we are fast losing the art of relaxation.Once you are in the habit of rushing through life,being on the go from morning till night,it is hard to slow down.But relaxation is essential for a healthy mind and body. Stress is fl natural part of everyday life.There is no way to avoid it, since it takes many and varied forms-driving in traffic,problems with personal relationships are all different forms of stress. _ .A certain amount of stress is vital to provide motivation and give purpose to life.It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can withstand depends very much on the individual.Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities.Others lose heart at the first sight of unusual difficulties.When exposed to stress,in whatever form,we react both chemically and physically.In fact we make a choice between "fight" or "fright" and in more primitive days the choice made the difference between life and death.The crisis we meet today are unlikely to be so extreme,but however little the stress,it involves the same response.All the energy is shifted to cope with the stress.It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress. Stress in some people produces stomach disorders,while others experience tension headaches.Since we cannot remove stress from our 1ires,We need to find ways to cope with it. Options: A Stress as well as relaxation is essential for a healthy mind and body. B Stress should not be rid completely from the life. C Stress produces both positive and negative effects on people. D People usually work better under stress if they are healthy. Answer: C Stress produces both positive and negative effects on people. Question:

A: What is the writer's attitude to stress according to the passage?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness treatments and depilatory creams, say Australian researchers. Researchers from CSIRO Mathematical and Information Sciences in prefix = st1 /Sydneyreport their findings in the November issue of the journalSkin Research and Technology. The software, developed with a UKcompany, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton. "Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said. The software relies on images captured by a small flatbed scanner pressed onto the skin. Using a mathematical algorithm , the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its straightness. The software is able to distinguish between hairs and other features on the skin such as wounds or moles . "Our skin irregularities make it difficult to say this is a hair or this is a mole," Dr Vallotton said. Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says. Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science. "We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said. To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual count. Dr Vallotton says the software could also be useful in testing the effectiveness of balding treatments and counting or tracing... Options: A A scanner. B A calculator. C A hair's unique feature. D A mathematical algorithm. Answer: A A scanner. Question:???
