Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

Traditional media such as printed newspapers and magazines has gradually declined in popularity, and digital media is attracting more and more users, and taking on a dominant role. Today, most people continue reading on a regular basis; however, their reading habits have changed. Many people are reading their favourite newspapers and magazines on their electronic devices such as computers, laptops, and smartphones. This has both benefits and drawbacks.

Printed and digital media can both have the same content, but digital media is usually faster and easier to access. In fact, the number of people buying a daily newspaper or magazine at stores has decreased dramatically. With the help of the Internet, readers can now access information that is updated instantly and receive the latest news from every corner of the world. In addition, electronic media doesn't use paper and is considered more environmentally friendly. Reading news online is generally free of charge, and can be done anytime and anywhere. Many news websites provide video reports or multimedia stories, so people can choose to hear, watch, or read news according to their preferences.

However, readers may face some problems as they read newspapers online. For example, an Internet user may be forced to watch or read all kinds of advertisements before getting to the piece of news he or she is interested in. Online adverts can be very distracting and annoying, and can make readers lose interest in what they are reading. In addition, many online publications focus much more on attracting viewers and followers rather than providing detailed or accurate information.

Nevertheless, digital media is an incredible source of news, information and knowledge, and its benefits outweigh the disadvantages.
