标题: OG阅读第85题不懂啊！！！

为什么The passage suggests that which of the following is a prediction concerning meteor streams that can be derived form both the conventional theories mentioned in line 18 and the new computer-derived theory?答案为什么是D: Meteor showers caused by older meteor streams should be , on average, longer in duration than those caused by very young meteor streams. OG的解释是说传统理论认为meteor streams随着时间推移涨大，但是line18不是说increasingly dense toward the center吗？我不懂啊！！！
