Question

read passage 1: \how trees get the dirt\ by elizabeth preston and then answer questions 1 - 9.

1. find this sentence from passage 1.

\the pea plants with isolated roots may as well have been sitting at home with no internet connection—they didn’t get the message...\ (paragraph 7)
the word \isolated\ comes from the latin root meaning \island.\ based on this information, what is the meaning of the word isolated as it is used in paragraph 7?
a. buried
b. attached
c. separated
d. entertained

Explanation:

root "island" implies something separated or alone. In the sentence, plants with isolated roots didn't get the message (like being disconnected), so "separated" matches. "Buried" (A) refers to covering, "attached" (B) is the opposite of separated, and "intertwined" (D) means connected, so they don't fit.

Answer:

C. separated
