- Why is Tom Robinson unable to use his left arm? -
B) It got caught in a cotton gin.
(B) is correct because Reverend Sykes tells the children (Scout, Jem, and Dill) that Tom got his hand caught in a cotton gin when he was a child.
~Hope I helped!~
B because this is the only one where the possessive s is in the right place
C. podium because a podium is an OBJECT and NOT an adjective. ;-)
I hope I helped! =D
Lowell uses a simile in the second and third line: “The world beats dead / Like a slackened drum.”
