这不是直接观察现实生活生态的例子,但它需要的知识相对的约会,所以我想我会来这里。[![图片拼图][1]][1][1]:https://i.stack.imgur.com/Uwifr.jpg这就是被告知:“虫子”(曲线)隧道通过一块材料,曾经是矩形。(C, D, F, J, H) -faintly-circled字母代表“裂缝”(不连续等缺点,我猜)(A, B, E, G, I) - D是“破”B(很难说图片)——尽管有十个字母,只有8人肯定可以放置。但是我们必须把字母顺序,说两个字母我们不能确定,并显示所有可能的其他字母可能被放置的地方。这是我迄今为止:首先我看着裂缝。E裂纹穿过一条裂缝。B裂纹穿过一条裂缝。我裂纹穿过裂缝。B G裂纹裂纹穿过。 I crack goes through G crack. G crack goes through A crack. Using principle of cross-cutting relationships, order from oldest to newest here is A, G, I, ((E,B) or (B,E)) Then I looked at the worms to the earthquakes. A --> F goes through A, but J is broken by A. B --> breaks C, H, F, J, and D E --> C goes through E, but J, D, F, and H are older. G --> C goes through G, but D is broken by G I --> F goes through I, but H is broken by I. Since B breaks all of the "worms" but E only breaks through four of the five "worms," we can place the cracks as, from oldest to youngest A, G, I, E, B Then I started to place the "worms" between the cracks using principle of cross-cutting relationships. I got in the end (oldest to youngest): J, A, G, I, F, E, C, B - D and H cannot be placed for certain. That's all I have for now and it seems a bit off to me, but I can't place where? Am I doing this right?
