根据下面短文回答下列问题。 Kathy and Polly were
friends but they liked playing tricks (花招，戏弄) on each other. One day Kathy met
Polly in the street. She said, "Hi, Polly. It’s good to see you."
"How can you see me when I’m not here" Polly asked.
"What do you mean, you’re not here" Kathy asked. "Of course you’re
here." "No, I’m not," Polly said, "and I’ll bet (打赌) you ten
dollars that I can prove (证明) I’m not here." "OK," said Kathy.
"Ten dollars. Now prove you’re not here." "Am I in Hong Kong
(香港)" Polly asked. "No," said Kathy. "Am I in
Paris (巴黎)" "No," said Kathy. "If I’m not in
Hong Kong and I’m not in Paris," Polly said, "then I must be somewhere else.
Right" "Right," said Kathy. "You must be somewhere
else." "If I’m somewhere else I can’t be here. Ten dollars,
please." "That’s very clever, Polly, but I can’t give you
the money." "Why not" "How can I give you ten
dollars if you’re not here" What did Polly say she could do
A. Prove she wasn’t there.
B. Give Kathy ten dollars.
C. Go to Hong Kong or Paris.
