Answer:
1. emission
4. poverty
Explanation:
1. I think we need a noun or V-ing here, but my choice is emission, behind a preposition.
4. Live in poverty - If I'm not wrong, it is a collocation
What’s the question?? I am confused!!
Based on the definition of appositive, this is a noun or noun phrase that is used to rename the another noun beside it. Basing on the given sentence above, I believe that it does not have an appositive. The nouns are Joe and Tulips, but no other noun that renames either of the two.
Hope this helps bro.
