Hmmm. #1 is pretty easy.
#2 is VERY easy.
Let’s work on #3.
Underline “contrast”. (You should know from doing a million VENN diagrams that contrast shows how things are DIFFERENT.)
Cross out “a” – Nothing in the selection about the dogs being in danger.
Cross out “d” – Farmers and ranchers are kind of the same thing.
I don’t think it’s “b”. Environmentalists want to protect the earth. They are into recycling and reducing pollution, etc.
Underline in text:
(in “Author’s Note” section under picture)
“protects predators such as wolves”, “protect herds from predators”
The words you underline are ALMOST exactly the same as the correct answer, and you do have to underline in two different places: THINK & SEARCH.
