Hi there,
I am referring to the explanation for the video question (Tropical bats play an ...). In this question since we have semicolons my question is as follows-
I thought that semicolon can be used ONLY if both the clauses before and after the semicolon are independent. Here "pollinating banana, breadfruit, and mango trees" doesnt stand out as an independent clause so how can it support the semicolon?

Howdy! You are almost corrected! Often semicolons are used in the way that you say—connecting independent clauses. But we can also use semicolons in lists, specifically when the items in the list contain commas. That happens to be the case here. :)

For more info on this use of the semicolon you can look here. See point (2) Supercommas

I hope that helps! :)

Cheers!

Mike, For OG Sentence Correction #29, I agree that answer "E" looks the best, but I have a question regarding the use of the "which". Given that "which" is supposed to touch what it is referring to, I was worried about picking this answer since "which is touching "Susan Huntington Dickinson" and not "letters". Is this permissible because the entire noun is "letters to Susan Huntington Dickinson"?

Hi Jacob! Happy to help! :)

(Quick clarification for anyone reading this comment: this question refers to a different question; not the one in the video above)

This is a great question and I am glad that you are thinking about modification. It something that can easily be overlooked.

So, Yes! We want our modifiers to touch the noun that they modify. But, as with a lot of English, there is an exception. If you have an intervening prepositional phrase that is essential, the touch rule does not apply. This is the case with SC #29. We have the essential prepositional phrase "to Susan Huntington," so our modifier does not have to touch "letters." The phrase still properly modifies "letters" even though it doesn't touch the noun.

I hope that this helps. :)
