This happens in conversations, where people are unsure if I have basic ability to read. I read fairly regularly throughout my life, and believe I’m able to. Is there a way to test & demonstrate whether I’m actually capable of reading, or if I’m e.g. reading without realizing that I’m not actually comprehending it?
Technically, one can listen to text and use dictation, so a person not knowing a single letter could perfectly understand and send texts on a smartphone or a computer.
But honestly, how does one get into a situation where they need to prove they can read? I think OP is in second grade and wants to cheat the test.
