Because the argument focuses on cost and why seawater is cheaper/better, find an answer that strengthens that. What makes the reason "seawater is cheaper?" look better? E does. E is saying "wow, pumping water for irrigation water is SO expensive", and that makes cheap seawater agriculture look great.

I got C right and then chose A during blind review. I see why C is right, but couldn't A technically be right? Even though it's not in the timeline, doesn't it strengthen the argument even more because it's giving evidence from 2 decades ago to support the issues in the past 5 years.

my first difficulty 5 question that I got right!

Any tips on timing? I rushed and picked E first time around, and then during blind review, I took my time and then realized C was the correct answer immediately.

I'm interested!
