Read the following passage and answer the questions.
Today, the educational value appealing to the eye as well as to the ear has been fully recognised, and the lack of suitable materials which has in the past been a handicap to visual education is being made good. The exhibition is one important medium for visual education that has gained greatly in popularity of recent years. Exhibitions may range in subject from the purely practical-such as those collections of artistic and historical interest like those circulated by the Victoria and Albert Museum. A natural focus for this particular form of education through the eye is the local museum. Museums and galleries are, indeed, playing an increasingly important part in the educational life of their localities; and possibly their greatest contribution can be made in the field of adult education. If they are valuable as a base for the display of material supplied from outside sources, they have a more important function of fostering local distinctions and tradition of all kinds. This they can do by their permanent collections, by special exhibitions circulated to other centres in the locality, for example, to colleges of further education or to community centres. An outstanding value of the exhibition method is that it does not provide instruction only, but by the display of works of craftsmanship and art it gives a training in appreciation, a sense of quality and individual character.
Another most important medium for visual education is the cine-film and at the present time the supply of specially produced educational films is being rapidly increased. The film, like the exhibition, is well adapted for demonstration of practical activities and skills of all kinds, and to the communication of cultural ideas and values. But it has a further distinctive contribution of particular importance in education. Owing to the exceptionally strong emotional impact of the cinema, films dealing with controversial topics - as, for example, the whole range of modern social questions - can be relied upon to provoke discussion and arouse interest in current problems. There are now a number of sources for educational films.
Mention should also be made of the humbler filmstrip, which consists of a series of pictures printed on lengths of cine film and projected like miniature lantern slides. Being cheap and easily handled, they are an ideal means for illustrating informal demonstrations and lectures. These are already obtainable for a wide range of subjects from several commercial producers, and are likely to be supplied in increasing number from public sources. For those who still prefer the ordinary lantern slide, the largest and most accessible public collection is that of the Victoria and Albert Museum.
