Answers Choices
○Algae are classified as symbiotic because they produce energy through the process of photosynthesis.
○The first successful plants on Hawaii were probably lichens, which consist of algae and fungi living in a symbiotic relationship.
○Lichens helped create favorable conditions for the growth of spore-producing plants such as ferns and mosses.
○Seed-bearing plants evolved much later than spore-producing plants, but both types of plants had evolved well before the formation of the Hawaiian Islands.


○Unlike spores, seeds must move to new habitats in order to have a strong chance of survival and growth.
○Seed-bearing plants arrived and spread quickly in Hawaii, thanks to characteristics that increased their seeds’ ability to survive and to move to different areas.

D选项说的是种子植物和孢子植物都是在夏威夷岛形成之前就有了啊。
这个不正是文中所说的吗？

你这个句子理解就错了，后半句说的是“两种植物在夏威夷岛形成之前就已经进化好了”，如果按照生物知识加上地理知识的话，种子植物孢子植物的确是在几亿年前久进化好了，但是请问文章有说夏威夷岛成型时间吗？还有文章原句也根本没有时间进行对比，这不是细节题的问题，而是根本就没有提及到， 我看了网上好多解释都是说细节题，这是误导，本身选项就未在文中提及，只有文勇新黄金阅读答案（拍照的那种）上说的是时间对比有问题

赞同楼上。 楼主，当时我做这个题的时候，我直接看到Seed-bearing plants evolved much later than spore-producing plants, but both types of plants had evolved well before the formation of the Hawaiian Islands. much later than我就删了。  只要文章没有提及的。 就直接忽略。
