The previous sentence states some fruits don't respond well to 1-MCP so this is and example of that.
This came from an SAT question:
Take Bartlett pears, for instance, unless they are treated with exactly the right amount of 1-MCP at exactly the right time, they will remain hard and green until they rot, and consumers who experience this will be unlikely to purchase them again.
A) No change B) pears, for instance: C) pears for instance, D) pears. For instance,
I went through with elimination.
"A" doesn't work because the comma set means that the sentence should still make sense without the words inside the comma set.
"B" doesn't work because the clause before the colon should be independent and make sense by itself which I think it doesn't because of the comma behind "pears"
"D" doesn't work because "Take Bartlett pears." is not an independent clause.
So I chose C but B is the answer. Could someone explain why B is right and C is wrong?
