The question posed is: Macroeconomic models indicate very different determinants of economic growth in the short run and long run. Is this true?

Critically assess this statement.

We are working with a macroeconomics book from Carlin & Soskice called: Macroeconomics: Institutions, Instability, and the Financial System

I just don't know how to approach the question. Are there any points I should consider and take into account?

Thank you. I know this is not a straight-forward question, but just an approach really help.
