Final answer:
Capsule size 5 has the smallest capacity among the given options. As the number of the capsule size increases, the capacity decreases, which places size 5 as the smallest.
Step-by-step explanation:
The size of a capsule is indicated by a number, and when it comes to capsule sizes, the higher the number, the smaller the capacity of the capsule. Therefore, you are looking for the capsule with the highest number in your options to determine which capsule size has the smallest capacity. In the list provided:
- Size 5
- Size 4
- Size 1
- Size 0
- Size 000
Size 5 is the capsule size that has the smallest capacity among the options listed. The sizes increase from 5 to 000, with 000 being much larger than size 5. So in a scenario where you are a traveler in an 'inner' space capsule the size of a vitamin pill, a capsule size 5 would represent the smallest internal volume.
