Which component is the two-wheeler maker's sag of two or three years when the economy slows?

Question 26

MediumOriginal question

A two-wheeler maker studies its monthly sales from 2010 to 2025. It notes four features: sales jump every October and November in the festival season; over the fifteen years they climb steadily as incomes rise; they sag for two or three years at a stretch when the wider economy slows, then recover; and they collapsed in April 2020 when a nationwide lockdown shut its showrooms.
