Read the passage carefully and choose the correct answer.

Reading, as you know, is a continuous and never ending process. If you do very little reading, or if you read only material that offers no challenge to your comprehension, your reading will be of very little use. Once we reach a certain age, or once our formal schooling is completed, many of us become so restricted in our choice of reading that we rarely read any new type of reading experience. We tend to read only books in our professional or business field, or only inspirational books, or only our favorite newspapers every morning, or only one magazine for which we have developed a preference. And the trouble starts here. You should neither read only for entertainment nor only for information, but you should also read for intellectual growth, for mental stimulation, for enriching your background of knowledge, for wisdom, and for broader outlook and mature understanding. What kind of books should you read to continue your intellectual growth, to gain a background for opinion and for judgment? The answer issimple one: Read books in fields you have little or no acquaintance with, books that will open for you new horizons of learning, books that will help you explore new areas of knowledge and experience, books that will make the world and people more understandable to you. Sadly, more and more people today are giving up the printed word in favor of being entertained and informed by watching TV, a popular entertainment, device present at almost homes. More and more children are being subjected to TV programming, perhaps as a babysitter. More than two hours of TV time per day are now a part of children development, generating physiological and mental problems that are of growing concern among experts.
