var cat = 3;

if (cat == 2) {

write("Good kitty");

} else if (cat == 3) {

write("Mean kitty");

} else if (cat == 1) {

write("Ugly kitty");

}

• Good kitty

• Mean kitty

• Ugly kitty

• true

Answer explanation

if (cat == 2) {

write("Good kitty");

} else if (cat == 3) {

write("Mean kitty");

} else if (cat == 1) {

write("Ugly kitty");

}

Since cat is assigned the value of 3, the else if statement of cat == 3 is true. So the write of Mean kitty is written.

What is the output?

var dog = 9;

if ( (dog > 2) && (dog < 13) ) {

write("I love dogs");

} else if ( dog < 5 ) {

• I love dogs

• I love cats

• true

• no output

Answer explanation

if ( (dog > 2) && (dog < 13) ) {

write("I love dogs");

} else if ( dog < 5 ) {

write("I love cats");

}

Since dog holds the value of 9, the first if statement evaluates to true. So the output is I love dogs. The else if statement will not be evaluated since the if statement is true.
