Self-study
The qwerty keyboard became the standard keyboard with the invention of the typewriter and remains the standard for typing devices today. ██ ██ ███████████ █████ ██ ███ ██████ ████████ ████ ███████ █████████ ███████ █████ ████ █████████████ ███████ █████████████ ██ ██ ███ █████████ ██ ██████ ██ ███ ██████ ████████ ███████ ███ ████ ██ ███████ ██ ██████████ ██ █████ ██ █████ ██████ ███ ████████████ █████ ██ ███████ ████ ███ ████████ ████ █████ ██ ██████████ ██████ ████ ██████ ███████
Summary
The qwerty keyboard is the standard for typing devices today. Another keyboard, the Dvorak, would allow people to type faster. But it’s not practical to switch to the Dvorak because the societal costs of switching (time, money, having to learn how to type on a new keyboard) outweigh the benefits gained from faster typing.
Strongly Supported Conclusions
People aren’t typing as fast they could be typing.
Sometimes it’s more practical to keep something that’s the societal standard even if a change could have some benefits.
3.
The example above best illustrates █████ ███ ██ ███ █████████ █████████████
a
Often it is ███ ██████████ ██ ████ ██ █ ███████ ████ ████████ █████ ██ ██ █████ ██ ███ ███████ ██ █████████
Unsupported. There’s no suggestion that the Dvorak keyboard is less accurate. Although there are cost associated with frustration of switching to the Dvorak, that doesn’t imply that anyone would be less accurate.
b
People usually settle ██ █ ████████ ███████ ████ ████████ ██ ████ █████████ ████ ███ █████████████
Unsupported. We don’t know why qwerty became the standard. There’s no suggestion it was the most efficient at the time it was adopted.
c
People often remain ████ ██ ██████████ ████████ ██████ ████ ████ ██ █ ████ █████████ ███████████ ██████ ███████ ████ ███████ ███████
Unsupported. That doesn’t imply people don’t want to switch from qwerty merely because they don’t like change. They might like change, but weigh the costs and benefits of a particular change.
d
The emotional cost ██████████ ████ ██████ ██ █ ██████ ████ █████████ █████████ █████████ ███████████████
Unsupported. The stimulus cites to frustration as one of the costs of switching to Dvorak. That doesn’t imply that the emotional cost of switching by itself outweighs the benefits of faster typing. It’s also not clear that faster typing is a financial consideration.
e
The fact that █ ████████ ██ ███████ ██ ████ ███ ███ ██ █ ███████ ██████ ██ ██████ ██ █ ████ █████████ ██████ ████ ██ ████████████
Strongly supported. Qwerty is the standard. The fact it’s standard increases the costs of switching, because it takes more time and money to switch every keyboard, and people need to learn Dvorak. These costs are an important reason keeping qwerty is more practical.
