What will print in the debug console?

• 35

• 5

• 45

Answer explanation

The answer is D since koala = 35 and bear = 5, koala adds 10 = 45. So, when we combine koala and bear we get 50 as our output.

What is the correct output?

• Less than 10

• Less than 20

• Less than 20

• Less than 30

• 40 or more

The answer is E since each time the score is called it adds onto the previous call of the variable.

What is the correct output?

• Output C

• Output E

• Output D

• Output A

Answer explanation

The answer is output D because it is the one conditional that is true due to the || (or) in the if-else-ifs.

What is the correct output?

• Hi You’ve got this!

• Hi Hi You’ve You’ve got this! got this!

• Hi You’ve got this! You’ve got this!

• Hi You’ve got this! Hi You’ve got this!

Answer explanation

The answer is C because line 1 will print Hi, then the function is called twice, so there will be two lines of You’ve got and two lines of this! printed one part on one line and the other on the following line.

You rock! cannot display. How can we change this in the event handler to make it display correctly?

• Line 1 change the global variable to total grade

• Line 3 take out var and remove the local variable

• Line 4 change grade to == 90

• Line 5 change to getText command

Answer explanation

The answer is B because we don’t want local variables since they will only focus on one event handler and not the entire program. Set the variables first so that they remain global instead. This way when you call the variable into an event handler, you do not use the var version of it.

• A country ruled by felines who like to scam people
