read this passage from “the city without us” by alan weisman:

the weeds are followed by the city’s most prolific exotic species, the chinese ailanthus tree. even with 8 million people around, ailanthus-otherwise innocently known as the tree-of-heaven-are implacable invaders capable of rooting in tiny chinks in subway tunnels. unnoticed until their spreading leaf canopies start poking from sidewalk grates. with no one to yank their seedlings, within five years powerful ailanthus roots are heaving up sidewalks and wreaking havoc in sewers-which are already stressed by all the plastic bags and old newspaper mush that no one is clearing away.

what does weisman’s word choice most clearly suggest about his feelings on the chinese ailanthus tree?

a. he respects the chinese ailanthus trees for their ability to survive under the harsh conditions of the city.
b. he fears chinese ailanthus trees because of their threat to new yorkers’ quality of life.
c. he uses the term “tree-of-heaven” to praise the chinese ailanthus trees for the beauty and exoticism they bring to new york.
d. he uses the phrase “implacable invaders” to reveal his disdain for the chinese ailanthus trees because of their destructiveness.
