1. The worm habitats differ considerably in size, location,
                                         ^^

did ten years ago.

疑問: 這題真的不懂了  我寫was

            ^^^^

推 cloud7556:#1. in表示哪些地方不同；from表示與某物不同
→ cloud7556:different from something in some ways
→ priv:#2 did 代替suffer所以不是was
→ priv:#3 如果like改用which are like應該可以
→ priv:alike的句型要用A and B are alike.
