QUESTION TEXT: Braille is a method of producing text…
QUESTION TYPE: Necessary Assumption
CONCLUSION: Anyone who reads Braille can learn to use this computer system.
REASONING: The device will use the same symbols as Braille.
ANALYSIS: This sounds like a good argument. But touching dots on a computer screen might be very different from touching dots on a page. Maybe people won’t be able to understand the computer dots.
___________
- The argument is only about whether Braille could be used. It doesn’t matter whether other systems could also be used.
- The argument will be stronger if everyone who can read Braille can use the new system.
- CORRECT. If this isn’t true then it’s hard to see how people could read the “Braille” on the new electronic screens.
- It’s not clear what this refers to. It doesn’t seem to have anything to do with Braille or computer screens.
- That’s nice. But the conclusion is about whether people can understand the computer screens, now.
