Question

instead of growing the same crop year after year, he practiced crop rotation to improve soil quality.
which word from a glossary entry best describes crop rotation as used in the sentence?
a. traditional: following long-standing customs
b. experimental: tested to see if it works
c. sustainable: designed to protect resources over time
d. seasonal: occurring during certain times of the year
p# 3

Explanation:

Crop rotation in the sentence is used to preserve soil quality over time by avoiding repeated planting of the same crop, which aligns with the definition of "sustainable" as practices that protect resources long-term. The other options do not fit: it is not described as traditional (long-standing custom), experimental (tested to see if it works), or seasonal (tied to specific times of year).

Answer:

C. sustainable: Designed to protect resources over time
