LR Question 1 Explanation

QUESTION TEXT: Braille is a method of producing text by means of…

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.

2. The argument will be stronger if everyone who can read Braille can use the new system.
3. CORRECT. If this isn’t true then it’s hard to see how people could read the “Braille” on the new electronic screens.
4. It’s not clear what this refers to. It doesn’t seem to have anything to do with Braille or computer screens.
5. That’s nice. But the conclusion is about whether people can understand the computer screens, now.
