TPO 25 - Question 4
A sample Answer to this speaking in text:
Cultural lag is a period of transition, when people get used to a technological change. The professor gives an example of the telephone. At the end of the nineteenth century, when telephone became widely available, only businesses used it. But the majority of the public didn’t value its use for personal communication, because, for example, some of them didn’t like to communicate without face-to-face, others considered it rude to call someone without visiting him or her in person. However, this attitude towards telephone changed over the 30 years thereafter. Talking to someone on the phone is no longer rude or abnormal. For example, friends like to call each other just for a chat, and the rules of politeness have also changed, like no one would consider the personal call impolite unless it is made late at night.
