3. how does tom robinson conduct himself on the witness stand? (1 point)

a. he is arrogant and moody.
b. he is nervous and shy.
c. he rarely speaks at all.

The people of Maycomb expect Tom to act very differently on the witness stand.  Tom is calm and gentle.  His is not at all the agitated and violent man they expected to see.

so I guess nervous and shy

c is the answer because first she would blush to make the reader wonder why which they find out in the next line.
