试题详情
题目：
Recent observations suggest that small, earthlike worlds form a very low percentage of the planets orbiting stars in the galaxy other than the sun. Of over two hundred planets that astronomers have detected around other stars, almost all are hundreds of times larger and heavier than the earth and orbit stars much smaller than the sun.
Which of the following, if true, would most weaken the above justification of the claim that earthlike worlds form a low percentage of the total number of planets?
选项:
A、There are millions of planets orbiting stars around which astronomers have not attempted to detect planets.
B、The best current astronomical theories predict that almost all planets around other stars are probably hundreds of times larger than the earth.
C、A planet orbiting a star similar to the sun would be more likely to be earthlike in size than would a planet orbiting a much smaller star.
D、The smaller a planet is relative to the star it orbits, the more difficult it is for astronomers to detect.
E、The observations would have detected any small, earthlike worlds orbiting the stars around which larger planets have been detected.
答案:
D

请问唐瑭老师，这个题是不是只看题干就可以了，不用回看原文？另外老师可以解释一下选项的有关无关吗

这道题做题时，原文读一遍感觉很晕，读选项感觉也是，只能蒙了下一题。回来review再读的时候（需要花多时间）能读懂明白为什么选D。但请问老师这类型比较难读的科技类逻辑题，考场有什么解题技巧吗？谢谢！
