Question

Why do you need to have separate variables - answer1, answer2, answer3 etc. 
 I used var answer = prompt('What season is it? [summer]');
if (answer.toLowerCase() === 'summer') {
    score += 1;
}
var answer = prompt('What day is it? [friday]');
if (answer.toLowerCase() === 'friday') {
    score += 1;
}
var answer = prompt('What color is the sky in November? [gray]');
if (answer.toLowerCase() === 'gray') {
    score += 1;
}
var answer = prompt('What year is it? [2016])');
if (parseInt(answer) === 2016) {
    score += 1;
}answer (just kept getting updated with each prompt response)

For this particular example, re-using a variable or using separate ones does not make a difference.
However, using separate variables allows an opportunity for program evolution where the individual answers might be referenced later on.  Once the answer variable is re-used, the possiblity of accessing the answer given to an earlier question is lost.
NOTE :point_right: A variable should only be declared (using "var") once.
You can re-assign it as much as you like but it should not be declared again.
