12 multiple choice 1 point
although its name literally means thousand feet, the __ with the most feet only has seven hundred fifty feet.
millipede
megapede
centipede
kilopede

Explanation:

1. One thousand thousands is $1000\times1000 = 1000000$, which is a million. There are no such terms as millithousand, thousand - million, or kilothousand in standard number naming.
2. The word "millipede" comes from Latin roots where "milli -" means thousand and "pede" means foot. Despite its name suggesting a thousand feet, the millipede with the most feet has only seven hundred fifty feet. There are no common terms like megapede, centipede (which has a different etymology and much fewer legs in general), or kilopede.

Answer:

1. D. million
2. A. millipede
