The answer is D. Sometimes you just need to read the sentence and trust your judgment. Only D, “As part of the …,” sounded right. Then I figured out the problem with the sentence so I could explain it. You need a preposition to begin the clause that explains the “part” each nation took in their “steps.”
Let’s see what the ACT folks are hiding on us this Easter morning!

The answer is B. They are “hiding” a question that we’ve seen before and it is an easy one at that. There are a couple of quick ways to do this question. First, you know that all those parentheses mean to multiply the x‘s times one another and that the shorthand way to express that math is to use an exponent. We have 4 x’s; so, we use the exponent 4.
Second, if you aren’t sure about the math, you could “change the abstract to the concrete” or “convert the algebra to arithmetic.” Substitute an easy actual number for the x. “1” is pretty easy! 1 times 1 four times is 1. Now plug 1 into the answers and see which one of them is equal to 1. The only one that works is B. We are all done.
Hope you have a great day whether you are celebrating Easter or not. Keep your sugar consumption under control!
