Final answer:
Pressing 'r' on your keyboard will not change the date in a date field to the last day of the current year. This task typically requires manual entry or using application-specific features, such as a date-picker tool or formulas in the case of spreadsheet software like Excel. To address the question of whether pressing 'r' on your keyboard will change the date in a date field to the last day of the current year, the answer is b) false.
Step-by-step explanation:
There is no standard keyboard shortcut that automatically changes a date field to the last day of the current year in most software applications. Changing a date usually requires manually entering the date or using a date-picker tool provided by the application.
In some programming environments or software applications, shortcuts or functions could be created to perform specific tasks like updating a date field, but these would be custom made and not a universal feature. For example, in Excel, one could use a formula like =DATE(YEAR(TODAY()),12,31) to get the last day of the current year, while in programming languages, functions or libraries can be used to manipulate dates accordingly. To change the date to the last day of the year manually, you would typically open the date field, delete the current date, and type in '12/31/' followed by the current year. Alternatively, many applications also offer a calendar pop-up where you can select the desired date directly.
