I'd probably say A or C. It's probably not going to be B.
Answer: between the last one and first one but my best guess is A
Explanation: Hope this helps!
There should be a comma between the words 'Wisconsin' and 'whose'
because since there is a peiod, the senences read
georgia o'kefe was an american painter from wisconson, meaning: georga o'keef, american, from wisconson
second one
whose detailed close-ups of flowers brought her world renown
this is a clause, the two sentances should be joined with a comma because theh though continues
the sentances should read:
"Georgia O'Keefe was an American painter from Wisconsin, whose detailed close-ups of flowers brought her world renown."
Every action has a cost. That’s as true for driving a car as it is for growing food and delivering it to your dinner plate. What we eat matters. The food choices we make every day have a big effect on the environment. The good news is that even small changes in what we buy and eat can add up to real environmental benefits, including fewer toxic chemicals, reduced global warming emissions, and the preservation of our ocean resources. Eating
"green” can also mean eating
fresher, healthier foods while
reducing your grocery bill and
supporting farmers. Choose local food options whenever possible
and avoid purchasing food imported by airplane.
But keep in mind that the type of food and how
it was produced may be of greater environmental
significance.
