I believe it is horrid, but I can't be sure...
The correct answer is A, "in two hours". It is the adverbial phrase of duration. B cannot be correct as it is an adjectival phrase, C is a sentence, or at least a fragment of a sentence, D is an object.
This question is incomplete. Here's the complete question.
Read: An Editorial: It's time for a nation to return the favor.
What is the “favor” in the editorial’s title?
Answer:
Since the entire country benefited from the economic activities of New Orleans, which could be considered a favor, it´s time for the nation to return that favor by protecting New Orleans of flooding and any possible new hurricane.
Explanation:
This editorial aims to convince the citizens of New Orleans to request Congress for help because they deserve it. Not only because they are part of the country, but also because the nation´s prosperity was boosted by the development of New Orleans. Furthermore, it was the weak levee system built by the federal government that caused the flooding after Hurricane Katrina.
Javan Rhino:
Engage local communities to develop long-term solutions to poaching, disease spread, and limited park space for rhinos. Maintain and build upon the current monitoring system established in 2013. Maintain at least 120 camera traps, and provide ongoing monitoring and analysis support.
Mahakam Dolphin:
In order to mitigate the conflicts with coal barges and the problems associated with swamp conversion for the oil palm industry, the local organization Yayasan Konservasi RASI (Rare Aquatic Species of Indonesia) is working to secure the last remaining core areas. RASI has proposed establishing a protected area and they already have 100% community agreement, as this protection will not only help the dolphins but it will also benefit local fish resources as well.
That's all I can help with, sorry. I hope this information helps!
