Answer:
This is because the key in relationships['jimmy'] is wrong. The first letter "j" should be uppercase. The key in the given dictionary is "Jimmy" and therefore a lowercase "j" will result in a KeyError exception.

The correct usage of key to address the value should be relationships["Jimmy"].

If you have purchased a printer that has the capability to print in duplex mode so that users can print on both sides of a sheet of paper. However, when users try to use this capability when they send a print job, documents are still printed on only one side. Then there might be a problem with (d) THE DUPLEX MODE NEEDS TO BE ENABLED ON THE DEVICE SETTINGS TAB IN THE PRINTER'S PROPERTIES.
Explanation:
- If the duplex mode isn't enable on the printer setting, then the printer is still going to read that the output should come in a single page and not in the duplex mode.
- When facing such a problem, the user should go to the "Device Settings" tab in the printer properties and change the required settings to print according to the users needs.
