An SI unit
Our answer book holds 48 answers to “An SI unit”, from the first thing anyone would say to names almost nobody would think of. Most people go straight for Metre, Second or Kilogram, so those barely lift the rocket. It is a fairly short list: only 5 answers sit in the two rarest tiers, so reaching one takes real knowledge.
The odd entry you read about once tends to score far better than the classroom example. You will find it in stage 32, “Charged Up”, of the Science mission. The first stages of every mission are free, and later stages come with the full mission.
