Answer:
b. This would set the group ownership of file1 to root.
Explanation:
Linux allows user to have his own files and regulate the ability of other users to access them. The <em>chown</em> command allows you to use the appropriate utility to change the owner of a file or directory.
The basic command syntax is as follows:
# chown [options] <owner name: owner group name> <file or directory name>
For example, if you want to give a user <em>root</em> opportunity to use the <em>file1.txt</em> file as he wishes, you can use the following command:
# chown root file1.txt
In addition to changing the owner of a file, the group of its owners or both can be changed at the same time. Use a colon to separate the username and user group name (without the space character):
# chown user2:group2 file1.txt
As a result, the user with the name <em>user2</em> will become the owner of the <em>file1.txt</em> and its group will become <em>group2</em>.
In your case omitting username
# chown :root file1.txt
will change owner group only.

Explanation:
Answer: The three RGB colors are each 8-bits (possible values [0.. 255], 2 to the power of 8 = 256) of each of Red, Green, and Blue. The three 8-bit RGB components can create up to 256×256×256 = 16.7 million possible RGB color combinations, called 24-bit "color".
Explanation:
Answer:
Here are the if/elif statements:
if tomatoes == 24: #if farmer sells exactly two dozen tomatoes
watermelons +=4 #farmer receives 4 watermelons
elif tomatoes >= 12: #else farmer sells at least a dozen tomatoes
watermelons +=2 #farmer receives 2 watermelons
else:
tomatoes<12
#On the days that farmer sells less than a dozen tomatoes
apples +=1 #farmer will get a single apple
Explanation:
You can test the working of these if elif statements by this program:
tomatoes = int(input("Enter the amount of tomatoes sold: ")) #prompts user to enter number of tomatoes
watermelons = 0 #initialize watermelons value to 1
apples = 0 #initialize apples value to 1
if tomatoes == 24:
watermelons +=4
elif tomatoes >= 12:
watermelons +=2
else:
tomatoes<12
apples +=1
print("Number of watermelons recieved: ",watermelons) #displays the received number of watermelons
print("Number of apples recieved: ",apples ) #displays the received number of apples
