A Spinning chair

Elly, Abby, Hayley found a shell-like plastic chair which can be spun round and round. Uncle HL Wat worked as the spinner. Every time when one of the girls sat inside, the orange curtain/blind was lowered and Uncle spun them as if they were on a Merry-go-round.

Hayley was the first to spin. We laughed several times when she walked out from the capsule chair on the lawn with unsteady steps. Probably she was a little dizzy after such spinning motions.

Doctor Sung suggested a method to reduce or minimize the dizzy effect. When one spins the chair in one direction, say clockwise, he should spin it in the the opposite direction, that is anti-clockwise, before he stops.

Abby was the next to try, then followed by Elly. At one time when Abby was sitting inside, Hayley and Elly attempted to spin the chair, but it was really difficult for them to do so.

Once Elly sat inside the chair and I acted as the spinner. What did she say to me inside when I was spinning the chair? Guess what she shouted to me. Below are the options.

A. Slower, slower!
B. Be Gentle!
C. Raise me up!
D. Faster, faster!
E. Stop, stop!
