Answer:
The account record comprises of Invoice roll up summary fields.
Explanation:
The possible reason that this change was not permitted was that the account record comprises of Invoice roll up summary fields.
Invoice roll up summary fields: A roll-up summary field computes values from associated records, for example those in a linked list. a person or someone ca design a roll-up summary field to show a value in a master record by building the values of fields in a particular record.
The detail record must be associated to the master through a master-detail relationship. for instance, you want to show the sum of invoice amounts for all linked custom object records in an account’s Invoices related list. you can show the whole or sum in a custom account field refereed to as Total Invoice Amount.

Answer:
These are the supplies in the list:
[‘pencil’, ‘notebook’, ‘backpack’, ‘pen’, ‘calculator’]
Explanation:
The line return (\n) character will be in the output (so there will be a change of line), but it will NOT be visible as it would have been interpreted as a special character.
So the output will be on 2 different lines, with no \n visible.
If the command would have been: print('These are the supplies in the list:\n', supplies), with single quotes (') instead of double quotes (") then then \n would have been printed but not interpreted as a special character. At least in most computer language. Since we don't know of which language the question refers to, we can't be sure at 100%.
