14. What is the fraction of housing in the assets of a typical US household? (1) 10%, (2) 30 %, (3) 50%, (4) 75%. Syntax: if your answer is (1) 10%, enter 1, not (1), and not 10%. Comment: you never need to remember the exact numbers (numbers change, estimates vary, you can always look up), but it is useful to know the approximate magnitudes for qualitative understanding (e.g. 10% and 50% in this question imply very different qualitative characteristics of the housing market) and for back of the envelope calculations w/o looking up every single number.
