题目： The passage suggests that which of the following
is a prediction concerning meteor streams that can be derived from both the
conventional theories mentioned in line 18 and the new computer-derived theory?
问从“conventional theories”和"new computer -derived theory"中可以看出什么。
文章中明确指出：“Coventional theories, however, predicted that
the distribution of particles would be increaingly dense toward the center of a
meteor stream.” 而"new computer -derived theory" 证明：“computer-model stream broadened with time”
这个和解释冲突啊，OG的解释说“conventional theories“ 也是说这个orbit会变宽，而不是变窄。 难道我又粗心了？？？ |
