<span>The option which hasn't greatly increased the speed of information dissemination is C. typewriter. Information can be easily and quickly shared through smartphones that have Internet access, through emails which you can send at any time, and through teleconferencing, which is basically using your camera to talk to people. The only technology which isn't really helpful nowadays is the typewriter - there are better things, such as computers, that do a better job today.</span>

Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}

Answer:
Explanation:
There are two reasons as to what could have happened with your laptop. The first one is that your laptop was installing a critical windows update which got corrupted when the laptop's battery died causing windows itself to become corrupted. In this case, you would need to format the hard drive and reinstall windows. The second reason could be that your hard drive is failing and not allowing Windows to load or properly be installed on it. In this second scenario you would need to buy and replace the hard drive.
