Based on the context and the answer, generate a question. 

Context: Mom , who has been our ward 's activity chairperson for the last while , dreamed up a pretty good activity last year - a pinewood derby . Now if you are familiar with Cub Scouts , you know this is usually something that is done by 7 - 10 year old boys ( and in the background , their fathers ) . However , Mom 's genius idea was to have families in the ward make a car and then race them . Last year my family just sat on the sidelines but for this year 's iteration of the activity we were ready .

Answer:

Their family build a car together and entered it in the wards race .



What did the family likely do this year that made the author say " they were ready " ?
