Read the following passage carefully and answer the questions on it.

      Have you ever considered the vast differences between the conventional desktop telephone and the modern handset telephone? The desktop telephone has one distinct function: that of making and receiving calls. Apart from that, perhaps the other use is aesthetic — adding some beauty to the furniture pieces in the room. The conventional telephone set was a status symbol, as only the rich and highly privileged could afford it.

      To obtain it, one had to fill many forms and have three well known citizens to attest to one's sterling qualities as a highly responsible member of the society. Then, after paying several fees, one had to wait for several months before the telecommunications department officials would come to install the wires, in order to get one's set connected to the national grid. After that, the applicant might count himself among the privileged ones in the community. But he must not heave a sigh of relief yet: his problem may just be beginning. The inclement weather may remind him that his use of the facility is at its mercy. A rainstorm or even a strong wind can destroy some of the wire-bearing poles, thus cutting him off from other telephone users. Besides, a vehicular accident may knock down a pole or several of them. It is not even uncommon for termites to render wooden poles useless. Finally, there are the problems of the communications department officials who are noted for bringing bills late, and cutting off wires for failure to pay up promptly. Most often, the bills bear little resemblance to actual consumption. Thus, the telephone is not always there at one s service.

      Like the conventional desktop telephone set, the handset has the primary function of making and receiving calls. Beyond that, there are vast differences between them. To begin with, the small handset is not much of a status symbol now. It is very easy to carry about and it can be used everywhere by all and sundry. The telephone service providers have flooded the market with lines at very low prices, such that most users can boast of two or more lines. Gone are the days when one had to apply for a set and wait for months. Today, all that it takes is to purchase the handset, which could be very cheap or very costly depending on one's preferences and purse. Once it is purchased, its user could have access to dozens of functions. Apart from making and receiving calls, one could send text messages and receive responses within minutes. The set could be used to take pictures which could be as clear as any taken with a professional camera. One could also connect to the internet to read newspapers and send mails. Besides, the set could be used to store songs; it could also be used as a radio receiver. One could use the handset to programme schedules of activities. The reliable timepiece on it could be used as a watch. Young ones play games on their handsets and store pictures of loved ones on them.

      However, with all these advantages, the handset has one obvious shortcoming: it can easily be lost or stolen. This is where the conventional desktop telephone is not vulnerable.
