Even though they naturally play a vital role in managing soil erosion and fertility, many small-scale farmers are hesitant to cultivate cover crops, which are grown in between traditional farming seasons, due to the heavy time and money investments required to farm them, opting instead to leave their farmlands fallow during such periods.
Meaning - Many small scale farmers, are hesitant to cultivate cover crops, which are xxxxx, because of the heavy time and money investments required to farm them(the crops). The farmers instead opt to leave the farmlands fallow. Cover crops play a vital role in managing soil erosion and fertility.
We need to show contrast here between "cover crops playing a vital role in xxxx" & "farmers not cultivating cover crops"
A. Even though
they naturally play a vital role in managing soil erosion and fertility,
many small-scale farmers are hesitant to cultivate
cover crops, which are grown in between traditional farming seasons,
due to the heavy time and money investments required to farm them - Misplaced modifier & Pronoun error. "Due to" is incorrectly modifying "Cover crops" - Incorrect
B.
Although cover crops, which are grown in between traditional farming seasons, naturally
play a vital role in managing soil erosion and fertility,
many small-scale farmers are hesitant to cultivate these crops
because of the heavy time and money investments required to farm them - Correct. Although X, Y...where X & Y are clauses
C. Even though they naturally play a vital role in managing soil erosion and fertility, cover crops, which are grown in between traditional farming seasons, are
hesitantly cultivated by many small-scale farmers because of the heavy time and money investments required to farm them - Passive voice, B is better.
D. Although
they naturally play a vital role in managing soil erosion and fertility,
many small-scale farmers are hesitant to cultivate cover crops,
crops that are grown in between traditional farming seasons because of the heavy time and money investments required to farm them - Same error as A, also meaning error - Incorrect
E. Even though
cover crops grow in between traditional farming seasons, naturally
playing a vital role in managing soil erosion and fertility,
many small-scale farmers are hesitant to cultivate these crops because they require heavy time and money investments - Ambiguous meaning, as the modifier "playing" is ambiguosly modifying both "cover crops" & "farmers" - Incorrect
Answer B.
