Option 1 -> While the opening is engaging, the specific command to breathe is directed at the reader's state of mind regarding their struggle rather than a mechanical hook to "make people read on."
Option 2 -> The passage addresses a common struggle with learning, but "pain" is too strong a term for a cognitive challenge; the intent is to address frustration rather than to "ease people's pain."
Option 3 -> This is the CORRECT statement. By telling the reader to "breathe" and adding "you're not alone," the writer aims to soothe the reader's frustration and "put people's anxiety at rest" before explaining the science of the difficulty.
Option 4 -> While the tone is conversational, the instruction to breathe is a supportive gesture of empathy regarding the difficulty of the task, not a device used to "introduce humour."
