An SI prefix
Our answer book holds 24 answers to “An SI prefix”, from the first thing anyone would say to names almost nobody would think of. The answers that come to mind first are Kilo, Mega and Milli. They count, but they keep you close to the ground. It is a fairly short list: only 4 answers sit in the two rarest tiers, so reaching one takes real knowledge.
Science questions often have a fixed list behind them, so working through it in your head can turn up answers others skip. You will find it in stage 46, “Shrink Ray”, of the Science mission. The first stages of every mission are free, and later stages come with the full mission.
