Question ID:PT63 S3 Q3 Passage:The qwerty keyboard became the standard keyboard with the invention of the typewriter and remains the standard for typing devices today. If an alternative known as the Dvorak keyboard were today's standard, typists would type significantly faster.

Choice C:People often remain with an entrenched standard rather than move to a more efficient alternative simply because they dislike change. Choice D:The emotional cost associated with change is a factor that sometimes outweighs financial considerations.
