Question

Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That’s every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”

Answer 1

【小題1】D
【小題1】C
【小題1】B
【小題1】A
【小題1】A

解析【小題1】根據(jù)Last month she explained to one of her classes about sound,可知選D
【小題1】根據(jù)and she decided to test them to see how successful she had been in her explanation.及下文描述，可知她想知道她的學生是否理解了她的課程，故選C
【小題1】根據(jù)Tom at once answered, “Your brother. Because electricity travels faster than sound waves.”可知選B
【小題1】根據(jù)“Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”可知選A
【小題1】僅僅按照物理學原理湯姆的答案是對的，但是考慮實際情況凱特的答案是正確的，故選A
