Hi Student Helper,
In chapter 12 of Manhattan SC 6 edition, I got two examples about the usage of infinitives.
1) The building WAS DEMOLISHED to avoid falling down accidentally. [Incorrect]
2) The building WAS DEMOLISHED to keep it from falling do accidentally. [Correct]
Here I understand it makes no sense that a building cannot avoid something, but I don't understand why a building can keep something intentionally, so that sentence 2) is correct.
Thank you.
Anna
