问题 Choose the correct letter, A, B, C or D.
Write the correct letter in boxes on your answer sheet.
According to the passage, it is determined that an elephant needs to communicate over long distances for its survival
选项 A、when a threatening predator appears.
B、when young elephants meet humans.
C、when older members of the herd want to flee from the group.
D、when a male elephant is in estrus.
答案A
解析 根据原文，大象在什么情况下，为了生存需要进行远距离的交流? 我们知道大象远距离交流一般是出于两个目的，要么是为了找配偶，便于繁殖，要么是为了警告捕食者的来袭。四个选项中A选项符合第2个目的。注意D选项“雄性大象在发情期时”为干扰项，文中提到了大象在找配偶时，所以不管是雄性还是雌性大象都会这么交流。因此，本题的答案为A。
