Article: Moods, say the experts, are feelings that tend to become fixed, influencing one's outlook for hours, days or even weeks.

Modern pharmacology offers a lot of tranquilizers What many people don't realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood.

Article: Folklore is the branch of the study of man which deals with local customs, tales and traditions. Everybody is a storehouse of folklore, though not everybody realizes it. Often, in deed, those who have never heard the word folklore have the greatest store of it, for the people with least book education commonly cherish most firmly old ideas and superstitions which have been passed on by word of mouth for generations. Everyone has heard stories of ghosts, witches, fairies, and giants. We all know some proverbs and have come across such ideas as, for example, that it is lucky to see black cat and unlucky to see a single magpie . We keep certain seasons of the year as festivals, such as Christmas, and we are familiar with the special customs connected with weddings and funerals. All such things are of interest to those who study folklore. People who study folklore won't criticize the old beliefs and practices they come across as silly, childish, or old-fashioned. Instead, they will try to collect accurate records of them and then see how these are connected with other ideas and customs of other places or times. By comparing with what is known of olden times or the folklore of other countries, they try to discover how certain beliefs and practices came into being, and what purpose _ serve now or used to serve in the past. Often we find that the beliefs which seem most peculiar and unreasonable, and the customs which appear least practical, are of the greatest interest and importance because they are commonly the oldest. Sometimes they were part of an ancient ritual or served a useful purpose when people's way of life was different from what it is now. So we not only learn about what people thought and did in the past but are better able to understand present customs. People often keep up customs when they have forgotten the original reason for them, and in the course of time a fresh reason gets attached to the custom. Thus, when some joker ties an old shoe to the back of the taxi taking the bride and... Question: Which of the following statements is true about customs?
