Q4. Where does **append** add a new element?

- To the end of an array.

Q5. Consider the following code that works on an array of integers:

`for i in range(len(values)):

if (values[i] < 0):

values[i] = values [i] * -1`

What does it do?

- Changes all negative numbers to positives.

Q6. Which of the following is NOT a reason to use arrays?

Q10. Consider the following code:

`tests = [78, 86, 83, 89, 92, 91, 94, 67, 72, 95]

sum = 0

for i in range(_____):

sum = sum + tests[i]

print("Class average: " + str((sum/_____)))`

What should go in the ____________ to make sure that the code correctly finds the average of the test scores?

SoloLearn has "challenges" which are a set of questions.

But I'd recommend coding challenges instead, since they are more technical and useful.
