   Braille is the only symbol system that can be readily adapted for use with the

   This is the famous style of trap answer on Nec Assump (and Must Be True) where they take the only thing mentioned and act like it's therefore the only thing. Braille was the only symbol system mentioned that can be adapted to the thermal screen, but that doesn't mean it's the only system than can be adapted.

   Only people who currently use braille as their sole medium for reading text will have the capacity to adapt to the

   Just like (A), this tries to turn the only thing mentioned into the only thing. The only people we mentioned using the thermal screen are people who currently use raised-dot braille, but that doesn't mean the author was assuming they're the only people who will use the thermal screen.

   People with the tactile ability to discriminate symbols in braille have an ability to discriminate similar patterns on

   Why this is right

   This is just affirming that people who know the raised dot system will similarly be able to handle the thermal screen system. If we negated it, it would badly weaken the argument. The people in the conclusion, who have the tactile ability to read braille letters with raised dots, would not be able to sense the same patterns on a flat heated surface. That would basically ruin the conclusion.

   Skill tested: Necessary Assumption · how this choice captures the argument's function is the move to repeat next time.

   Some symbol systems encode a piece of text by using dots that replicate the shape of

   It doesn't matter whether any symbol system replicate the shape of the letters of the alphabet. Maybe the Braile equivalent of "R" is a bunch of dots in the shape of an R, but maybe it's just a bunch of dots like this: :: It doesn't matter whether it's in the shape of an R or not. A braille reader would recognize that "::" means R. The only question is whether a braille reader would recognize the heated thermal screen equivalent of "::" as R.

   Out of Scope: initial training1% picked this

   Eventually it will be possible to train people to read braille by first training them in the use

   The argument is only about whether people who currently read the raised dots can also read the thermal screen. The author didn't need to assume anything about how we will train braille readers in the future.
