### Subject: SAT

How should the word in parentheses be edited in order to make the following sentence make the most sense? Rwandan conservationist Edwin Sabuhoro is taking a new approach to wildlife poaching prevention: luring poachers away from crime by (trained) them to become farmers.

Instead of using trained, it would make more sense to say 'training' because it follows the parallel structure of other verbs in the sentence like 'poaching' and 'luring'

### Subject: Geometry

If two angles of a triangle are 37 degrees and 63 degrees, is the triangle acute, obtuse or right?

Because all three angles of a triangle always add up to 180, we can solve for the third angle to determine what kind of triangle we're dealing with. 180 - 37 - 63 = 80 degrees. The 37, 63 and 80 degree angles are all acute angles and so therefore the triangle is acute.

### Subject: Calculus

What is the integral of 3/x^4 with respect to x?

In order to find the integral of 3/x^4, we can make use of the power rule by rewriting the equation as 3x^-4. The power rule states that the integral of x^n is (1/(n+1))*x^(n+1), so in this case we would have (1/(-4+1))*x^(-4+1), which simplifies to (-1/3)x^-3, which can be rewritten as -1/(3x^3)
