Depends on your operating system. For any system not Chrome OS, folder creation is an organizational must. Your hard drive stores data sequentially in the form of bits. Whenever you want to access information on your hard drive, the drive has to, much like an array in programming, run through all the data until it comes across the desired file. This, as you could probably imagine, is cumbersome. We, as the users, have the luxury of not having to deal with that kind of information acquisition. We can create folders and directories into which we can place files. The reason I mentioned Chrome OS earlier, was because Chrome OS stores just about everything in the cloud. There isn't any real need to create directories on a Chrome system because all of that data can be managed and stored on Google's servers, as opposed to in files and organized by yourself.
"The increased availability of mobile digital devices has had a positive impact on how young people use their free time."
There are many different views that you could take upon this subject.

2) You could say that the increased availability of mobile digital devices allows for children to occupy themselves by providing games, videos, books, and other things to provide them with entertainment, a learning experience, and more.
Hope this helps!

I would pick A B and D to be my answer
Answer:
def sum_1k(M):
s = 0
for k in range(1, M+1):
s = s + 1.0/k
return s
def test_sum_1k():
expected_value = 1.0+1.0/2+1.0/3
computed_value = sum_1k(3)
if expected_value == computed_value:
print("Test is successful")
else:
print("Test is NOT successful")
test_sum_1k()
Explanation:
It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.
- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.
- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message
- Call the <em>test_sum_1k()</em> to see the result
