Answer : 1. "DPI "
Explanation :

Laser printer resolution is specified in terms of DPI, which stands for Dots Per Inch. DPI refers to the number of dots a printer can place within one square inch of space on a printed page. Higher DPI values generally result in sharper and more detailed printouts. Laser printers typically offer higher DPI resolutions, such as 600 DPI or 1200 DPI, leading to high-quality text and graphics output.

Answer : 3. "ctrl+down arrow "
Explanation :

Actually, in MS PowerPoint (and most other word processing applications), the key combination to move down one paragraph is "Enter". Pressing the "Enter" key moves the cursor to the next paragraph. If you want to move the cursor down one line within the same paragraph, you can use the "Down Arrow" key. There isn't a specific default key combination to move down one paragraph in PowerPoint; it's more about using the "Enter" key to start a new paragraph.
