问题 Choose the correct letter, A, B, C or D.
Write the correct letter in boxes on your answer sheet. [br] 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。
