请教两题，迷惑

LSAT TEST 4——SECTION 1 ：18题（B），为什么不选D？19题（C）为什么不选B？

谢谢解答

18.D， Practicing veterinarians have a professional obligation to strive to prevent the unnecessary death of an animal except in cases of severely ill or injured animals whose prospects for recovery are dim.  扩大推理范围，提干无法推出狗死是unnecessary death of an animal。

这种题目在gmat中应该不会考。

19.B的结论是：trees growing in the Pazyryk Valley have annual rings that are quite distinct from trees growing in nearby valleys. 根本和判断age无关的说。

那再请问19题？想不通

谢谢18题的解答

谢谢ATONGMU 的解答和意见，由于我是从本站下载的ELSAT，不知道什么原因，无法将原题复制到这里，如果要TYPE，那太长了，请谅解，不过我会尽力。

不好意思，对于这两题，我还是不明白。其实这两个答案都是乱选的，因为我实在觉得选不出来。

18）的正确答案B的疑问：从题干哪里看出“杀死动物是毫无理由的，除非这能立即帮助拯救其他动物的生命或保护人类的健康？？？”

19）的正确答案C疑问：只是说HAS AMONG ITS RINGS A SEQUENCE OF TWELVE ANNUAL RINGS REPRESENTING。。。。，并不是说所有RINGS，那如果剩下的一部分RINGS无法识别，那原来对年龄的推断不是就不精确吗？  想不通！这就是我迷惑的地方。

希望能再稍加指点，很感激。
