(Horton the Elephant, who is surely among the most lovable of all Dr seuss’s creations and) represents kindness, trustworthiness, and perspective – all wrapped up in a comical and even absurd package.

Why is the above mentioned wrong or worse as opposed to: (Surely among the the most popular of all Dr seuss’s creations, Horton the Elephant).

Is it because “who” should only be used for people?

Thanks!

The diagram includes a parabola with the point (6, 1).
“The figure above shows the graph of the quadratic function f(x)=a(x-4)^2+b, where a and b are constants. Which of the following number lines represents the set of all values that satisfy the inequality f(x)=a(x-4)^2+b <= 1?"

The answer was between 2 and 6 inclusive, but not sure how to get to it? (May 2013 SAT)

Thanks!
