Answer 1

A mobile phone (also known as a hand phone, cell phone, or cellular telephone[1]) is a small portable radio telephone.

The mobile phone can be used to communicate over long distances without wires. It works by communicating with a nearby base station (also called a "cell site") which connects it to the main phone network. When moving, if the mobile phone gets too far away from the cell it is connected to, that cell sends a message to another cell to tell the new cell to take over the call. This is called a "hand off," and the call continues with the new cell the phone is connected to. The hand-off is done so well and carefully that the user will usually never even know that the call was transferred to another cell.

As mobile phones became more popular, they began to cost less money, and more people could afford them. Monthly plans became available for rates as low as US$30 or US$40 a month. Cell phones have become so cheap to own that they have mostly replaced pay phones and phone booths except for urban areas with many people.

In the 21st century, a new type of mobile phone, called smartphones, have become popular. Now, more people are using smartphones than the old kind of mobile phone, which are called feature phones.[

Answer 2

OPTION B

$\mathbb{\underline{EXPLANATION}}$

↪ When we refer to cause-effect , it means that a particular event has occurred and therefore that event has an effect or a cause .

↪ In the passage a description has to be written and hence we cannot use the cause-effect .

↪ The problem/solution is n't applicable to the passage .

↪ The OPTION A tells classification which is correct but not " MOST EFFECTIVE " .

↪ The OPTION B is the most effective option according to me .

↪ It tells us about chronological type .

↪ Chronology means series of events and their brief description in the correct order .

↪ This suits the passage better than other options .
