PROBLEM: Article: Typing Success in 20 Minutes a Day -- Teaching Your K-12 Students to Type in 20 Minutes a Day Typing is fast becoming an important skill in our world. Making this skill available to your students is very important. Just 20 minutes of the following activities per day will give your students the finger strength and keyboard knowledge they need to be ready to include typing in their learning programs. Step 1 Knitting  : You can try various styles until you find the one that best suits your students' abilities. Finger knitting is a great way to start! It helps students focus on finger strength. Knitting with needles is a little more challenging but will suit some older    students. The more practice the fingers get the stronger they will become.

Students as young as four years old can practice finger placement, letter sounds and names using the keyboard of computers. Step 3 Clay modeling: Many children develop the ability to be quick and skilful with their hands through creating clay models. The creative nature of this activity keeps children engaged for long periods of time. It helps keep fingers strong and supple. Step 4 Lego   building: Little fingers become strong when children pull apart little Lego time and time again. Because of the fun nature of this activity it helps build and does a lot to reinforce the ability to arrange things into an order -- another important aspect in typing.

PROBLEM: Article: What does the future hold for the problem of housing? A good deal depends, of course, on the meaning of "future". If one is thinking in terms of science fiction and the space age, it is at least possible to assume that man will have solved such trivial and earthly problems as housing. Writers of science fiction, from H.G. Wells onwards, have had little to say on the subject. They have conveyed the suggestion that men will live in great comfort, with every imaginable apparatus  to make life smooth, healthy and easy, if not happy. But they have not said what his house will be made of. Perhaps some new building material, as yet unimagined, will have been discovered or invented at least. One may be certain that bricks and mortar(,) will long have gone out of fashion. But the problems of the next generation or two can more readily be imagined. Scientists have already pointed out that unless something is done either to restrict the world's rapid growth in population or to discover and develop new sources of food (or both), millions of people will be dying of starvation or at the best suffering from underfeeding before this century is out. But nobody has yet worked out any plan for housing these growing populations. Admittedly the worst situations will occur in the hottest parts of the world, where housing can be light structure or in backward areas where standards are traditionally low. But even the minimum shelter requires materials of some kind and in the teeming, bulging towns the low-standard "housing" of flattened petrol cans and dirty canvas is far more wasteful of ground space than can be tolerated. Since the war, Hong Kong has suffered the kind of crisis which is likely to arise in many other places during the next generation. Literally millions of refugees arrived to swell the already growing population and emergency steps had to be taken rapidly to prevent squalor and disease and the spread crime. The city is tackling the situation energetically and enormous blocks of tenements are rising at an astonishing aped. But Hong Kong is only one small part of what will certainly become a vast problem and not merely a housing problem, because when population grows at this rate there are accompanying problems of education, transport, hospital services, drainage, water supply and so on. Not every area may give the same resources as Hong Kong to draw upon and the search for quicker and cheaper methods of construction must never stop. 
 Answer: bricks and mortar will be replaced by some other building material.

SOLUTION: The writer is sure that in the distant future   _  .
