Question

If a line has seven feet, a poem is written in _____.

trimeter
tetrameter
pentameter
heptameter

Answer 1

Tri means 3rd,
Tetra means 4th,
pent- means 5th,
hex- means 6th,
hept- means 7th,
octa- means 8th,
non- means 9th,
dec- means 10th.

It says The line is 7 feet, so it'll be heptameter.

Answer 2

"Tri" means three, "tetra" means four, "penta" means five, and "hepta" means seven, so heptameter is the best answer. :)

(This also means that poems written with three feet per line would be trimeter, with five feet per line would be pentameter, etc.)
