Question

turned to see his neighbor professor horgan, who taught math at the city college nearby and often rode the same bus as jayson.

smiling gratefully at her, jayson started over, but he was able to remember only two more digits after the 6 and then he faltered again.

\try creating a mnemonic,\ professor horgan suggested, but jayson only gave her a puzzled look, so she offered an explanation. \it is a memory trick, like using roygbiv to remember the colors of the rainbow. you know: red, orange, yellow, and so on.\

how might a mnemonic help jayson?

it might help him get accepted into a nearby college.
it might help him remember more digits of pi.
it might help him understand the professors words.
it might help him communicate his confusion better.

Explanation:

The text states Jayson is struggling to remember digits (implied to be of pi, as he recalled digits after 6) and the professor suggests a mnemonic, a memory trick, to help with recall. The other options are unrelated to the context of his memory struggle.

Answer:

B. It might help him remember more digits of pi.
