HOTS: If someone ignored the idea “Always write units”, what mistake could they make while solving a question from Measurement of Time and Motion?
Answer
They would use the wrong term or the reverse relation. Remember: Always write units. Always check the NCERT definition before jumping to a formula or a long explanation.
Explanation
HOTS items ask you to predict an error. That is still chapter revision — not a claim that this exact wording will appear in the board exam.
