A message contains sarcasm but the receiver interprets it as a normal statement. Which reason is possible?

Correct answer: Failure to understand tone and context

Sarcasm often depends on tone, shared knowledge, facial expression, or surrounding context rather than the literal words alone. In a text message these cues may be weak or absent, so the receiver may decode the sentence literally. Colour, the receiver’s name, or message length does not explain the misunderstanding by itself.
