Which of these is the best way to send a document, e.g. a copy of a letter, electronically to another party?
A . As a PDF
B . As a JPEG
C . As a Word document
D . As a spreadsheet

Answer: A

Explanation:

PDFs contain all the information for a document, e.g. layout, sizing, images etc., within themselves. This means that they do not rely on the recipient having the same software as you to interpret the document, and so eliminates the chances of misunderstanding through changes in format etc. Documents can be saved as PDFs from most common word processing software.
